Accurately Reverse Engineering an Assembly

EmailFacebookGoogle+LinkedInTwitterShare

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

EmailFacebookGoogle+LinkedInTwitterShare

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 […]

Tips and Tricks for VX Model: Patching Holes

EmailFacebookGoogle+LinkedInTwitterShare

Anyone familiar with 3D scanning knows that small holes in your scan are inevitable. Whether they are screw holes, pinholes, countersunk, or counterbore, you just can’t always capture the entirety of a small hole. Now, this begs the questions: “Do you just ignore them, or do you fix them?”. This depends entirely on what your scan is being used for. If you’re scanning to extract a surface from a mold design, then maybe you can just ignore those screw holes […]

Creaform has three main portable 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 relevant to the geometry being scanned. Last time we looked at the Go!SCAN so this time we will take a dive into the HandySCAN. The HandySCAN differs quite a bit from how the Go!SCAN works. Where the Go!SCAN uses a white […]

  On-Demand Personalization is on the Rise In today’s modern age, the new size is custom. With giant strides in technology like 3D printing and 3D scanning, what used to be cost-prohibitive customization is now possible. With the movement of e-commerce by consumers, it also brought about the ability to do away with off-the-shelf, one-size fits all purchasing. Consumers are looking not only at aesthetics and beauty in products but also quality, comfort and unique fit. This movement can be […]

Scan to CAD Comparison in VXModel to Double Check Reverse Engineered Models

EmailFacebookGoogle+LinkedInTwitterShare

So you’ve spent some effort to go through the 3D scanning and reverse engineering process in VXModel to get yourself to a fully parametric CAD model. How can you check to make sure your model is accurate to the scan, or the design intent assumptions you made did not throw geometry too far out of spec? Here we will be looking at a quick and easy way to get an answer at a glance. Lets first take a look at […]

Creaform has three main portable 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. Lets take a look a the different methods each scanner uses to help identify which scanner could work better for your application. Keep in mind that this is just one aspect to choosing which scanner […]

Getting Sharper Edges from Creaform Scans using VXmodel

EmailFacebookGoogle+LinkedInTwitterShare

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. […]

Automating Inspection Reports with CREAFORM and PolyWorks

EmailFacebookGoogle+LinkedInTwitterShare

    Batch inspections in metrology When we have to measure large batches of parts with precision and speed, it’s imperative to find every advantage to improve our repeatability and minimize cycle time. Traditional CMM (coordinated measuring machine) measuring systems and the associated software are usually too slow to meet the very short cycles required for batch inspection. Moreover, they create a bottle neck in the operation workflow with every part flowing through one QC operator. When this happens, a […]

Creaform is constantly working to improve upon their products for greater speed, accuracy, and ease of use. Part of that never ending goal is software improvements within Creaform’s VXElements software packages. A service pack update for VXElements 6.2 has just been released, correcting a few bugs found since 6.2’s release earlier this year in May. See below for a list of those specific fixes. BUG FIXES VXElements: Fixed a bug where probing a single point would trigger a Multishot acquisition […]
