Geomagic Design X: The Impact of Regions when Reverse Engineering

EmailFacebookLinkedInTwitterShare

As discussed in my previous blog, Geomagic Design X gives engineers a very powerful tool for reverse engineering.  One of the reasons mentioned was the segmentation of the mesh into regions.  This allows users to start sketches off of the planar regions.  Also, primitives, both solids and surfaces, can be created by selecting regions.  Surfaces can also be fit to regions to create more organic shapes. The first step is that the mesh needs to be segmented using the Auto […]

Verifying Concentricity with 3D scanning

EmailFacebookLinkedInTwitterShare

Concentricity is considered one of the most difficult GD&T measurements to acquire due to the need to create many center points along a cylindrical feature, yet its a critical measurement in many industries. In the automotive industry, concentricity is used in applications from transmission gears which need to be coaxial to avoid wear, all the way to airbag pneumatics to prevent loss of pressure. But what makes concentricity so difficult to do? Well, we can use the example of verifying […]

Customer Story: Avance Design

Step into Avance Design in Indianapolis, IN on any given day, and the whole team’s firing on all cylinders. Just speaking with Business Development Manager Bill Fletcher briefly, the array of projects their team is working on at the moment is incredibly diverse: they’re 3D printing 90 fixtures, designing the CAD model of a snow shovel, creating CAD data from a 3D scanned part for a machine part where the original data was no longer on file with the manufacturer, […]

3D Scanning: Using a Work In Progress (WIP) Model with a Roland CNC

EmailFacebookLinkedInTwitterShare

Creaform 3D Scanners can be used for many more things beyond quality control/inspection of parts or reverse engineering existing parts. With more uses comes less downtime on your Creaform scanner resulting in a better return on investment. One of the less prominent areas you can use your scanner for is to make a ‘Work In Progress’ (WIP) model for use with CNC machining. Sometimes when machining you will have a part that is part way machined from the stock but not […]

Benefits of Using Geomagic Design X in Reverse Engineering

EmailFacebookLinkedInTwitterShare

VXmodel is a great tool for reverse engineering (RE). It has a direct transfer to SOLIDWORKS, SolidEdge, and Inventor. The process, as shown here, is a simple one. Create entities in VXmodel, transfer them to CAD, and then use them to guide the RE process. However, like Tim Taylor, I sometimes like “More power!” That extra power comes with Geomagic Design X. Unlike VXmodel, Design X comes with it’s own CAD backbone. This means that the entire RE process is […]

From Scan to SOLIDWORKS in a Few Simple Steps

EmailFacebookLinkedInTwitterShare

One of the great benefits of 3D scanning is the ability to quickly turn a physical model into a digital model for CAD design.  There are 2 main methods for achieving a CAD model using 3D scanning: Method 1. Extract information from the scanned data in parametric form to rebuild in CAD software. Method 2. Extract a non-uniform rational basis spline (NURBS) Surface from the scanned data. Both methods result in a usable CAD model, method 1 requires the user to […]

Creaform Scanning with HandySCAN 700

EmailFacebookLinkedInTwitterShare

How fast can you scan a part? Some of the most common questions asked during a Trade Show Creaform Product demo fall along this thread: “How fast is the scanner?” “What does a 1min scan look like?” “Can you get good data in under a minute?”  “What if I only care about this one section of the part, will that speed up the process?” In order to better understand their needs, I ask about their current measurement methodology. I also […]

Creaform 3D scanner tracking, MetraSCAN

EmailFacebookLinkedInTwitterShare

Creaform has three main 3D scanners for collecting surface data information. There is the Go!SCAN, the HandySCAN, and the MetraSCAN. All three of these have different ways in which they figure out where they are in 3D space relative to the geometry being scanned. Previously, we looked at the Go!SCAN and HandySCAN so this time we will take a dive into the MetraSCAN. The MetraSCAN is the largest of the Creaform scanners, both in size of the scanner itself and […]

Accurately Reverse Engineering an Assembly

EmailFacebookLinkedInTwitterShare

Reverse engineering an assembly accurately at the part level and determining how the parts fit together can be challenging. I ran into a simple example of this while recreating a tissues holder for our office. A coworker of mine has an Easter Island head tissue holder that has been broken. In this case, the head had come unglued from the base and would not stay upright without falling off.  Luckily it could stay together when laying down.  We’ll go over […]

New Feature of Vxelements 6.3

EmailFacebookLinkedInTwitterShare

New to CREAFORM’s Vxelements 6.3 is the ability to perform an automatic pre-alignment between your scan and CAD model for inspection. One of the most powerful things about inspection software is the ability to perform fitting calculations and with this new functionality, extracting critical feature information is that much easier.   Prior to release 6.3, CREAFORM used a point-pair method for creating best-fit alignment. Essentially the user would pick a minimum of 3 points that are in the same location […]
