Press Release: ZEISS Industrial Metrology Signs PADT as an Authorized Distributor of its COMET® Series of Blue Light 3D Optical Scanners

Scanning is one of the fastest growing parts of PADT’s business, and with the announcement of a new agreement to distribute for ZEISS Industrial Metrology, we are growing even faster.  Blue Light 3D Optical Scanners are amazing devices that allow users to create accurate surface maps of almost any geometry.  We have been using this technology in-house for our scanner services for some time, now we wanted to also make them available to our customers.

You may remember when PADT announced that we had partnered with Steinbichler to provide 3D optical scanners.  Well, we are not dumping Steinbichler.  Their technology was acquired by ZEISS Industrial Metrology.  We have been waiting for the acquisition to finish up and for the Steinbichler team to be fully integrated before we signed up to represent these fantastic devices again.  That happened and we are back selling them in Arizona, Colorado, New Mexico, and Utah.

What we like about these optical devices are the incredibly accurate lenses, from ZEISS, and the large and accurate CCD chips.  This combination gives fantastic quality.  In addition, we can swap out different lenses for specific applications and the software that comes with the system is outstanding.  After beating our device to death last year on services work, we feel very comfortable recommending it to all of our customers.

Here is a video on the primary product we are selling, the ZEISS L3D 2:

And that is also the advantage of buying your optical scanning solution from PADT. We use this stuff every day on a variety of applications. So we understand our needs, and we know how to get the most out of the hardware and software. So when you are making your decision on what to buy, and when you need support once you have made your investment, you know PADT is the best option to help you out.

Press Release:

ZEISS Industrial Metrology Signs PADT as an Authorized Distributor of its COMET® Series of Blue Light 3D Optical Scanners

PADT Customers Seeking to Bring Precise Inspection Services or Reverse Engineering In-house Now Have World-class Equipment at Their Fingertips

TEMPE, Ariz., February 27, 2018 Phoenix Analysis and Design Technologies (PADT), the Southwest’s largest provider of simulation, product development, and 3D Printing services and products, today announced it has signed an agreement with ZEISS Industrial Metrology to become an authorized distributor of the COMET Series ®  product line of Blue Light Optical Scanners. ZEISS Industrial Metrology is a business group of ZEISS and is a worldwide leading supplier of optical and contact measuring technology.

“When we made the strategic decision to add scanning devices to our distribution portfolio, we evaluated all of the leading structured light 3D optical scanning systems,” said Rey Chu, co-owner and principal, PADT. “The ZEISS COMET clearly emerged as our preferred choice. Not only did it serve as a workhorse, results were more efficient and accurate and we could scan a wider variety of objects. The ZEISS COMET is the obvious choice for our customers who want to bring inspection or reverse engineering services in-house.”

Scanners in the COMET Series utilize the latest blue light technology to capture 3D data accurately and fast. The system operates by projecting patterned light, also called structured light, onto an object and the camera captures the image. The Colin3D software processes the image and creates a 3D “point cloud” with millions of points. The software further processes point cloud data for downstream applications – reverse engineering, inspection and rapid prototyping to name a few. The portable COMET series has two models – COMET 6 and COMET LƎD 2.

“PADT was selected as an authorized distributor of our COMET Series because of its depth and breadth of knowledge of engineering services and 3D scanning technology,” said John Grzybowski, business sales manager at ZEISS Industrial Metrology. “They serve as an excellent partner and a valued ambassador of the ZEISS brand.”

What we Learned at the Geomagic Conference about Design X and Control X

On September 11th and 12th Mario Vargas (Hardware Manager for PADT Inc.) and I (James Barker, Application Engineer for PADT Inc.) attended Convergence 2017 in Los Angeles, CA.  This event is held by 3D Systems and is the America’s Software Partner Meeting.  Many strategic partners were in attendance from all across the USA, Canada, and Latin America.  We were able to learn about some new enhancements to Geomagic that will help you with Inspection or Reverse Engineering BIG time!  The first day of meetings we heard from Vyomesh Joshi (CEO of 3D Systems referred to as VJ).  He mentioned that 3D Systems has committed 17% to R&D and after going to this event it is apparent!  VJ briefly talked about each of their software options.  The 1st being Control X and how Polyworks currently has the edge for inspection software but after this next software release, he and other 3D Systems employees seemed confident that they could surpass Polyworks.  The 2nd software he talked about was Freeform which allows users to freely design parts by using a haptic device.  This software would be great for creating custom shapes on a whim.  If you haven’t tried a haptic device, you need to!  It will blow your mind as a designer with the freedom you get by using the haptic device and this Freeform Software.  The 3rd software he talked about was Cimatron which aids in the design of mold and die design.  Of the top 10 largest USA mold makers, 7 of them use Cimatron Software.  The 4th software is something new that will be released later this month.  I would love to tell you more about it but can’t….  sorry!

A little about why Mario and I attended this convention, PADT Inc. offers 3D Scanning as both a service and also as hardware or software you can buy.  We use both Geomagic Design X and Geomagic Control X and have experts that are scanning parts for customers for either inspection results or for reverse engineering purposes at our Tempe, AZ office.  The scanner that we use is a CMM quality scanner from Zeiss.  This scanner is capable of scanning 5 million points per scan!  We also offer 3D Systems Capture and Capture Mini scanners which are great tools for reverse engineering.  Each time they scan a part they are capturing about 1 million points per scan.  I am located in the Salt Lake City, Utah office and have a Capture Mini scanner that anyone wanting to see and demo, can come look at and evaluate at our office.  Same holds true for the Capture scanner and Zeiss scanner in our Tempe, AZ Headquarters.  Since we offer these services, we love knowing what new tools are available with these product releases.

Jumping back to the conference, on September 12th, there were breakout sessions.  We chose to go to the Geomagic Design X session to see what enhancements have been made.  This software is the preferred software in all of the industry for reverse engineering parts.  There were many different vendors/partners in the room we were at.  There was even a rep from Faro who prefers to sell Geomagic Design X software with each Faro Arm that he sells because this software is so powerful.  The neat thing about this software is all of the improvements that have been made to it.  If you are accustomed to designing parts with Solidworks, Solidedge, NX, Catia, Pro-E or any of the other CAD software, you will be able to use this software with ease.  Every command that you execute within Design X is editable just like the major CAD software.  You have the ability to create sketches on planes or to make life even easier, there are wizards that automatically create sketches and perform a command like an extrusion or revolve that is editable after completing the wizard.  After you have finished reverse engineering your parts within Design X, you can live transfer your new CAD data over to the above-mentioned CAD software.  Once you have imported this data into NX or Solidworks, you can again edit any of the sketches that were created within Design X but now in your software of choice!  I would love to show you how powerful this software is.  There is a reason why it is the preferred reverse engineering software in the industry.

Geomagic Control X session was next.  It also happened to be the last session of the day.  To be honest, I have only used Design X so I was looking forward to learning more about this software.  From all the demo’s that I have seen in the past from this software, it appeared really hard to use.  That is all changing with this new software release and is the reason why VJ is confident that it will compete and could exceed Polyworks as the preferred software for inspection.  The biggest thing that stuck out to me was the ability to set up a workflow for scanned data for inspection so that you can create your inspection reports.  The idea is that if you have a part that needs to be inspected for quality, you 3D scan the part and then import the CAD file.  By overlaying the scanned data over the CAD data you can show the deviation within the 2 parts and you are able to have different views in a 3D PDF to share with others the actual quality of the part.  As you are assigning your GD&T to this first inspection file, you are creating the first steps of the workflow.  There are many options for the workflow that you can create and 3D Systems has made it easy to create the workflow.  I feel that the power of this software is when you can open up the results of the first inspection report and do a split screen on your monitor to show the 100th or 1,000th part side by side and see how that part deviates from the first.

I had a great time in California at this event even though all of our time was spent at the hotel.  The streets looked nice from the window on the 11th floor.  Maybe next time we will venture out!  If anyone from 3D Systems is reading this, let’s go out to eat next time instead of eating at the hotel for breakfast, lunch, and dinner!  Although the view from the dining room was nice!

If you have any questions about 3D scanning whether it is for Inspection or for Reverse Engineering, let us know at PADT Inc.  We look forward to helping you.

Getting to Know PADT: Part Scanning and Reverse Engineering

This is the first installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

Product innovation doesn’t always start with a blank sheet. Many times our customers need to begin with an accurate representation of their existing products, or a piece that theirs interfaces with, or even a competitive solutions.  That is why we offer scanning and reverse engineering services that take real world parts and convert them into an accurate and useful CAD model.

What is Part Scanning

Part scanning is a process where we use machines to measure geometry.  Before scanning someone would use rulers, calipers, and other measuring devices dating from the industrial revolution to get critical dimensions off of a part and painstakingly document what they find. That got better with Coordinate Measuring Machines (CMM) where you could accurately measure key locations on the geometry. The problem with this approach was that it only gave you data where you measured.  Fine for simple parts like a flange with bolt holes.  But not good when you have crazy free-form surfaces or many features. Another approach was to section the parts and project a shadow onto a piece of paper and trace it.  If you needed more measurements, cost went way up.

To solve this problem, people found a way to measure lots of points easily: scan the part with some sort of optical sensor and measure points on the part as you go.  Early scanning systems used lasers, measuring the beam that bounced back.  This worked well, especially for very large objects.  But was tricky on some surfaces and produced a lot of noise in the data. So researches figured out that they could project patterns of light and dark onto an object and measure how the edges of that pattern bent and warped.   This is called Structured Light Scanning, and Wikipedia has a good article giving more details on how it works. We use the “blue light” version of this process here at PADT for our optical scanning services.

The other process we use is Cross Sectional Scanning. As the name implies it scans the cross section of parts, and it does it by actually shaving off material one layer at a time and then taking a picture of the 2D cross section that is revealed.  Although you consume the part in the process, it is a very accurate and fairly affordable way to measure complex internal geometry.

What you get from both scanning approaches is what we call a point cloud.  What is a point cloud? A file with millions of points defined as an X, Y, and Z position in space that represent locations that sit on the surfaces of the object.  You can measure critical dimensions, compare different geometries, and use it as a basis to create a computer model.  The key thing to note is that PADT uses precise scanners and leading software, combined with the experience of our operators to produce an accurate and usable point cloud.

Creating Accurate Models from Scan Data – Reverse Engineering

For most projects, getting the point cloud is just the first step. In order for our customers to redesign, update, simulate, or interface with the part we scanned, they need an accurate computer model.  Instead of millions of points, the computer model contains a more concise mathematical representation of the surface defined by the points. The simplest thing we can do is simply fit triangles through those points.  This is refered to as a faceted model because it is made up of triangular facets.  This data is used for 3D Printing, rendering, and for design in some cases.  Most often we deliver an STL file for this type of model. If a more accurate representation is needed, our engineers can convert those facets into an actual Computer Aided Design (CAD) model.  It can be just a dumb solid, or we can even make key features parametric.  The geometry can be handed over in many different formats, including IGES, Paraolids, STEP, SolidWorks, SolidEdge, NX, or CREO.

How Part Scanning with PADT Different

To be blunt, the reason why we added scanning to our capabilities was that we had always outsourced this service for our customers.  We found plenty of people with scanners, but they just scanned a part, ran the software, and provided OK data for our customers.  The problem was they were not experts in the technology behind scanning, they lacked a theoretical understanding of math behind 3D computer geometry modeling, and they were not experts in product development.  It turned out that scanning the geometry was the easy part, what our customers needed was someone who knew how to scan it right and produce useful information.  Information they didn’t have to spend time cleaning and massaging. Our engineers combine all of these skills along with a firm understanding of quality requirements, GD&T, and most of the major CAD systems.  In addition, PADT is ITAR compliant and can deal with your confidential geometry and data requirements.  The fact that PADT is a recognized expert in Additive Manufacturing is often useful as well.  We could not find a service provider that had all of the things our customers required, so we decided to do it ourselves.

Leveraging PADT’s Part Scanning and Reverse Engineering Services

Getting parts scanned by PADT is actually fairly easy.  Step one is to contact PADT and talk to our engineers so they can produce a quote.  Ideally it is best for you to bring the part or parts in to our Tempe office. If that is not feasible we will need some basic pictures of your part and key dimensions like maximum length, width, and height. They will then talk with you to understand what you actually want to accomplish by scanning.  Armed with this information they will provide a quote for scanning and any geometry creation or other activities you need completed including cost, schedule, and a list of deliverables.

In  most cases, you will ship us or drop off the part or parts, and our team will go to work.  If needed, we can also come to where the parts are located and scan them there.  The deliverables vary from job to job, and are negotiated as part of the quoting process.  In general we will provide you with an STL or CAD file with the level of accuracy and detail that you ask for. If needed, we can also provide you with the point cloud  itself.  We can also complete inspection reports and provide comparisons between datasets.

Part Scanning – An Update

3d-optical-scanner-1Did you know that PADT does scanning of parts?  No? You are not alone. We recently ran into several customers who were sending their scanning out of state and didn’t know that they could have it done by PADT, someone who is already a trusted partner. So we thought it would be a good time to do an update on our Scanning services and provide some additional background on what it is.

Part Scanning 101

The idea behind part scanning is that you want to take a part in the real world, and get an accurate model in a computer. To do this you somehow measure the part with a computer, getting a three dimensional representation of the parts surface.  Today, there are six basic ways to do this:


Physical Measurement (CMM)
Measure points on the part relative to some reference. This is great for measure simple geometry where you can reconstruct it by knowing key dimensions.
scanning-laser-scanningLaser Scanning
This process shines a laser on an object and measures the distance to the object. It does this thousands of times to build up a point array of the surface


scanning-structured-lightStructured Light Scanning
This process puts down a series of parallel lines, or a grid of lines, and measures how far they distort from a flat pattern. With this information it can create a massive amount of points on the objects surface.

scanning-cssCross Sectional Scanning
If you need to see inside, light based scanning does not work. In cross sectional scanning you machine away thin slices of an object and take an accurate picture of each layer as you go. This can then be turned in to an accurate representation of both the inside and outside of the object.
scanning-ct-scannerVolumetric Scanning
Another way around the fact that light can not penetrate an object is to use various types of radiation, like X-Rays, that go inside an object. Although new for industrial applications this method is growing for complex parts with internal geometry.
scanning-photometric-scanningPhotometric Scanning
If accuracy is not critical, then software can take pictures taken from dozens of views and reconstruct a 3D shape.  This is used most often for art and entertainment, but is not precise enough for engineering yet.

PADT offers Structured Light and Cross Sectional Scanning

scanning-point-cloud-surfaceAll of these methods create points in space.  The more sophisticated the software, the more automatic the process of assembling the points to define the surfaces of the full object. These points are sometimes called a “point cloud.”

The Point cloud can them be turned in to a faceted representation of the object.  For many people, this is all they need. This faceted representation can be rendered on a computer screen or 3D Printed.  It can also be used with inspection software to determine the accuracy of the part relative to its original specification as well as variations across multiple copies of the same geometry.

scanning-CAD-modelIf users need more, like a full CAD model, that can be created from the point cloud using specialized software.  PADT uses Geomagic DesignX.  This tool not only creates usable geometry, but it can export in the customer’s native CAD format.

To do accurate part scanning you need:

  1. A precision scanning device
  2. Software to take the measured data and create an accurate point cloud. This includes repair and cleanup tools.
  3. Software to convert the point cloud into a usable 3D CAD model
  4. or, Software to conduct accurate inspection on the measured geometry.

All of these tools require some training and practice to use efficiently.  It is fairly easy to get ball park computer models using consumer level tools. But to get accurate, engineering quality results the right tools and processes must be applied.

Why does Part Scanning Take so Long and Cost So Much?

When people ask for their first part scanning quote, they can often be surprised by the cost. The scanning process doesn’t look that hard. And to be honest, the amount of time you actually spend scanning most parts is pretty short.  The time is spent on the preparation, scanning hard-to-reach areas, the clean up, and then converting the data in to usable formats.

scanning-doing-the-workIf we are working with a light based scanner, we have to prepare the parts so that they reflect the light properly. Sometimes we have to cover the part with a find powder, sometimes we may even have to paint it.  What we need is for the reflection and color of the part to not interfere with the scanning.

If we are using cross sectional scanning, the part needs to be cast inside a rigid material, so the part we are scanning does not distort as we remove layers.  In addition, if the part is not a solid light or dark color, it may need to be died to provide contrast for the camera.

Both processes also require some study to determine the orientation of the part relative to the scanner and how the scanning process will take place. Once all this is worked out, the scanning often goes very fast. If there are nasty little parts that are hard to get to or that confuse the device, the engineer may have to modify things, do some special localized scanning, or even make castings that are then scanned.  As is usual with technical processes, a very small portion of the surface being scanned may take up the vast majority of the scanning time.

Once the scanning is done, the real hard work begins. Although software is much better than it was in the past, the resulting point cloud needs to be massaged and cleaned. Stray data is removed, and points from different scans need to be positioned and combined.  Then everything must be checked. If a CAD solid model is needed, then the engineer must spend considerable time dealing with complex features and transition areas. As with the scanning, the bulk of the time spent creating a CAD model is spent on a relatively small percentage of the geometry.

All of this adds up.  Plus, to be honest, things rarely go as planned and unexpected issues arise that need to be dealt with.

Part Scanning Services at PADT

scanning-geomagic-1Now we get to the important part of this post: hiring PADT to do your scanning.  We added this capability to support our 3D Printing customers that wanted copies of physical parts.  But as we looked at it, we found that we also had customers who needed inspection and reverse engineering of legacy parts. We studied the problem for some time and found the right tools and people to make it happen.

Our primary scanner is a Zeiss Comet L3D 5M STructured light scanner.  It used to be called a Steinbichler, till Zeiss bought them in 2015.  Although it is portable and easy to manipulate, the Comet L3D 5M is highly accurate.  It allows us to scan everything from small medical devices to the front end of acar, and to know that the resulting geometry will be accurate and usable. This is the best option for inspection and reverse engineering of high-precision parts.

scanning-padt-partsWe also have a Geomagic Capture scanner. Although less accurate it is more portable and simpler to operate. It is ideal or taking to a customer and getting geometry for reverse engineering or part copying.

If parts have internal features, and are made of plastic, we use our Cross Sectional Scanners. These high precision devices do a fantastic job and are really the best way to capture inside surfaces. Our customers love it to see how injection molded parts are coming out on well used molds.

If anything else is needed, our experts can outsource to a niche supplier.

Want to do it Yourself?

If you need to do your own scanning, no worries. PADT also sells all the tools we use inhouse to customers that need the capability internally.

Press Release: Fast, Intuitive, and Precise 3D Scanning Solution from Steinbichler Added to PADT’s Portfolio

steinbichler-PADT-multiproduct-1Yes. Another press release from PADT announcing a new partner.  The truth is we have the advantage of having worked with some great companies in 2014 and we are now fortunate enough to be able to add several of the great products we use in-house to our product offering. It all kind of happened at once.  Don't worry, we are almost done… only one or two more surprises out there.

At the beginning of the year we mentioned that we were offering full professional optical scanning. That service was based on using a Steinbichler blue light scanner. And as is usually with a tool we really like, we quickly negotiated an agreement with that company to represent their products. They offer the COMET line of blue light scanners and the T-SCAN line of laser scanners. There is of course a nice software package, called colin3D, that serves as a way to interact with the devices and get the data into a useful form. Both technologies offer high-precision at a reasonable price, something that not only PADT, but many of our customers were looking for.  

Please find the official press release below or as a PDF file.  You can also learn more about the products on our website here. We hope to schedule some webinars on this tool, and publish some blog articles, in the coming months. But the best way to try out this technology is to have us scan a part for you.

geoCUBE: Computers for Scanning

PADT just released a line of computer workstations  specifically designed for use with a variety of optical scanners: geoCUBE Scanning Workstations.

Scanning technology has come a long way.  It is relatively easy to scan a real physical part with a variety of different scanning technologies and capture the geometry for use in inspection, design, reverse engineering, or to directly replicate a part with 3D Printing.  The problem is that a good scanner produces a huge  number of data points and a standard office computer, laptop, or even most CAD workstations bog down and perhaps even crash when you try to view or manipulate that much data.  

geocube-hardware-picsWhen we ran into that exact problem here at PADT when we were doing scanning services for customers.  On a nice CAD workstation it was taking almost a whole day to clean up and process a full scan or a large part.  Our manufacturing team asked if they could power one of the CUBE Simulation Computers we use for CFD.  If you know CFD people you know they said “No, but can I also run on your box if you are not using it?”  So they went to our IT staff, the people who design CUBE systems and asked for a custom built machine for scanning.

The result was a breakthrough.  That 20 hour job was finishing in about two hours and we were able to spin the points and the resulting triangle file around on the screen in real time. We liked it so much we decided to come up with four systems spanning the needs of scanning users, and offer them along with the scanner we sell, or to anyone that might need one.

Below is a screen shot of the table showing the four systems, from a basic small box that you can use to drive your scanner, to the power system that we use.  You can download the brochure here, or visit the web page here

Scanning Helps Pediatric Heart Surgeon Make Implant Choices

heart-assist-deviceThe week we had the opportunity to help a surgeon make better decisions for their pediatric heart patient.  Dr Stephen Paphal from the Phoenix Children’s Heart Center had a young patient that needed a ventricular assist device. He could implant a device that they knew would fit in the patient, but they also had an alternative, larger device that performs better. The question they needed to answer was: will the larger device fit in the patient?

This surgeon’s team has previously done work using mechanical engineering technology to help them make better decisions, you may have read about their use of 3D Printing to evaluate different treatment options.  They often work with computer models of patients and devices n collaboration with spinal surgeon Dr. Sandro LaRocca in New Jersey, so they had almost all the tools they needed to help this patient.

For this case, they had a computer model of the smaller assist device, and a computer model of the patient’s heart area that they extracted from a CAT scan. Using those two models and visualization software they were able to insert the device model into the body model to verify that the smaller device would fit.

The issue they faced was that they had no computer model for the larger device.  Creating a model the traditional way would take to long. So they called PADT and asked if we could scan the actual object and give them a computer model that they could use.

Just in Time Scanning

One of PADT’s engineer, Johnathon Wright, took the device to our Geomagic Capture blue light scanner to extract a surface model from the real part.  In this image you can see the device being scanned:

heart-assist-scan-on-tableBecause the device is reflective, we covered it with a white powder to get a better scan. That is all the preparation needed.  The part was placed on a very sophisticated rotational displacement device (a $10 Lazy Susan from WalMart) and the scanner is turned on.  The  little reflective dots you can see on the Lazy Susan are used by the scanning software to determine the position of the objects relative to the scanner.

In this image you can see what the part looks like to the scanner:heart-assist-blue-light-scan-1A rectangular pattern of blue light is projected on to the part being scanned, and the included software measures the distortion in the grid to calculate the shape of the object. As you rotate the object (or the scanner) more data is gathered and an accurate point cloud of the external surface is created.

Here is what the point cloud looks like when the scan is completed:

In about an hour, Johnathon was able to go from “can you do this” to a water-tight solid that the Doctor could use with his computer model of the patient to see if this larger, better part fit in the patient’s chest.

Here is what the whole setup looks like:

heart-assist-scan-2

Johnathon used Geomagic’s scanning tools running on a PADT CUBE computer that is specifically optimized for scanning to make the process faster and more accurate. In the past, a task like this would have required an expensive and temperamental laser scanner, a dedicated lab, and probably four to eight hours of engineering time to clean up the resulting scan data. As you can see, the device sits on a desktop and requires very little infrastructure or special equipment.

Disruptive Technology

Any day we can help a physician strive for a better surgical outcome is a good day. Beyond that this is also a great example of how three important aspects of the technology enabled us to deliver useful information quickly, making desktop scanning a disruptive technology.

The first key technology is the blue-light scanning itself.  A form of structure-light 3D scanning, this approach uses a blue light because it contrasts the object better. The breakthrough with this technology is that it does not require expensive lasers or complex optics.  Faster computing allows for the complex algorithms used to be quickly and accurately applied.  The approach does not require any special equipment beyond the scanner itself. This results in an affordable device that is easily deployed and operated.  How easy, the 3D motion capture device on the Microsoft Xbox Kinect is a structure-light 3D scanner – using infrared light instead of blue.

Modern software used to convert the scan data into useful information is the second technology deployed for this solution.  In the past the process of calculating the points on a scanned surface, cleaning up spurious data, and converting it to a form that could be easily used was tedious and difficult.  The Geomagic software suite has a modern, intuitive user interface that sits on top of very sophisticated tools that automate many of the steps that used to take us hours to carry out.

The final key technology that makes desktop scanning so disruptive is one that we take for grated today: standards. We were able to produce an STL file from the scan data and the Doctor’s team was able to read that directly in to their visualization software. It is a simple thing, but without standard file formats, transferring so much data would also involve translators which introduce errors and time.

Engineering Better Outcomes

Here at PADT we truly enjoy applying technology developed in the Aerospace or electronics space to other industries, especially medical applications.  This is another great example of how useful engineering tools can be, improving someones life directly.

A 3D Mouse Testimonial

The following is from an email that I received from Johnathon Wright.  I think he likes his brand new 3DConnexion Space Pilot Pro.

top-panel-deviceRecently PADT became a certified reseller for 3Dconnexion. Shortly following the agreement a sleek and elegant SpacePilot PRO landed on my desk. Immediately the ergonomic design, LCD display, and blue LED under the space ball appealed to the techie inside of me. As a new 3D mouse user I was a little skeptical about the effectiveness of this little machine, yet it quickly has gained my trust as an invaluable tool to any Designer or Engineer. On a daily basis it allows me to seamlessly transition from CAD to 3D printing software and then to Geomagic Scanning software, allowing dynamic control of my models, screen views, hotkeys and shortcuts.

Outside of its consistency as an exceptional 3D modeling aid, the SpacePilot PRO also has a configurable home screen that allows quick navigation of email, calendar or tasks. This ensures that I can keep in touch with my team without having to ever leave my engineering programs, which is invaluable to my production on a daily basis. Whether you are a first time user who is looking to tryout a 3D Mouse for the first time or an experienced 3D mouse user who is looking to upgrade, you need to check out the SpacePilot Pro. I can’t imagine returning to producing CAD models or manipulating scan data without one. Combine the SpacePilot PRO cross-compatibility with its programmability and ease of use and you have a quality computer tool that applies to a wide range of users who are looking at new ways to increase productivity.
