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 […]

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 […]

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 […]

SOLIDWORKS 2019 What’s New – Creating Geometry-based Boundary Conditions in SOLIDWORKS Plastics – #SW2019

EmailFacebookLinkedInTwitterShare

One of the essential steps in SOLIDWORKS Plastics is to setup the Boundary Conditions for the simulation. This includes creating the injection locations, the control valve locations, and setting the mold wall temperatures. In the past, these were somewhat limited. When placed down they are not placed exactly where you click, instead they snap to the nearest node in the mesh. This is especially an issue with coarse meshes. To be set precisely, injection and control valve locations needed to […]

Getting Sharper Edges from Creaform Scans using VXmodel

EmailFacebookLinkedInTwitterShare

Sometimes when reverse engineering, a fully functional CAD model designed with a full feature is not needed. With the Creaform VXmodel software, a “dumb” solid body can be made from a watertight mesh using the “Auto surface” command. However, sharp corners become rounded due to resolution. By increasing the resolution this can be fixed to a certain extent, but it will never become that sharp edge of the scanned model. Also, flat faces will be mostly flat, but not perfect. […]

3D Scanning – Mesh Alignment and Merge for Parts that Require Multiple Scans

EmailFacebookLinkedInTwitterShare

When 3D scanning, sometimes it is necessary to use multiple scans to capture the entirety of an object. When still in Creaform’s VXscan, scans can be merged so that the complete object is in the single scan. However, if the meshes are brought into Creaform’s VXelements from another source, the meshes cannot be merged in the normal way. In this case they can still be merged, but some steps have to be taken first. Both scans will need to be aligned exactly […]

What I learned at AMUG 2018!

EmailFacebookLinkedInTwitterShare

Recently we were able to participate and attend the annual Additive Manufacturing User Group(AMUG) Conference. This was my first year attending and I had a blast! The booths were fun to explore with many different printers and complimentary solutions. In our booth we had a Stratasys F170 the first day and a Desktop Metal Studio printer the rest of the week. As complimentary solutions, we also had a Roland MDX-50 benchtop CNC milling machine, and a variety of Creaform 3D scanners. There […]

Importance of 3D Scanners in Reverse Engineering

EmailFacebookLinkedInTwitterShare

In my role as Reverse Engineering Specialist with CATI, I have seen many methods used in reverse engineering. I have used quite a few of them also. In this blog, we are going to look at the various techniques to gain a better understanding of why 3D Scanners are so helpful in this area and how other techniques can be used. The first method I ever used is the “Sketch Picture” method. This is used when you don’t actually have […]

Deep Dive into Reverse Engineering a 3D Scanned Propeller

EmailFacebookLinkedInTwitterShare

One of the main uses of 3D Scanners is reverse engineering, and this may seem like a daunting task. Today, we will be taking a look at this process and how we can accomplish this using VXmodel and SOLIDWORKS. For our example, we’ll be reverse engineering a propeller. Once we have our 3D scanned propeller, we need to properly align it so that the origin and planes correspond with our CAD system to avoid extra steps later on in the […]

Scanning the Tallest Man in the World

Scanning the Tallest Man in the World The Guinness Book World record for tallest man in the world was a man named Robert Wadlow from Alton Illinois who stood at 8 ft 11.1 in tall.  Since he died in 1940, I obviously did not get to scan him.  But courtesy of the Collections of the St Louis Science Center, St Louis, Missouri; I was able to scan one of his shoes.  For this scan I used the Creaform GoScan 20.
