Detecting and Correcting Non-Manifold Geometry

Detecting and Correcting Non-Manifold Geometry

The MagicHeal Add-On for TransMagic now includes a powerful set of tools that help you with detecting and correcting non-manifold geometry. This is important because failing to detect non-manifold geometry can lead to problems downstream, when you are trying to use that geometry in a CAD system (such as SOLIDWORKS or Solid Edge) that does not support non-manifold geometry. What does Non-Manifold mean? Manifold is a geometric topology term that means: To allow disjoint lumps to exist in a single logical body. Non-Manifold then means: All disjoint lumps must be their own logical body. See a more detailed description of non-manifold geometry in this article. Two...

Missing CAD Data

Missing CAD Data

‘Missing CAD Data’ summarizes the many reasons you may not be able to find your CAD data. If you need more information on any of these areas, see the links and embedded videos at the end of each section. Empty Assemblies – CAD assemblies typically need parts in order to have any real CAD content. If your customer sends you a folder full of assembly files, and no part files, you probably have an empty assembly on your hands. Contact your customer and ask for the missing parts. Missing PMI – Sometimes there is no PMI (Product Manufacturing Information), sometimes the user just forgot to attach it, and sometimes it just needs to be turned...
Brep vs Visrep Models

Brep vs Visrep Models

What are the advantages of Brep vs Visrep models, and how do you tell them apart? Brep Models Brep refers to Boundary Representation. As the name suggests, the boundary between solid and non-solid geometry is in view here, the solid geometry being a collection of interconnected surfaces. This is a mathematically precise representation of geometry. Depending on the format and the CAD software you have in your possession, the features and underlying sketches may be editable, or the shapes may be editable – but generally speaking, if you don’t have the CAD system used to create the file, you cannot edit the features or sketches unless you run a...
CAD Format Analysis

CAD Format Analysis

What CAD format, and what version, did that colleague just give you? Most of the time it’s clear what format it is, and most of the time the version doesn’t matter, BUT – sometimes it does. This is a repost from a few years back. It has turned out to be one of our most referenced resources, so here it is again! The following CAD Format Analysis cheat-sheet will allow you to open up CAD files in a text editor like Notepad or Notepad ++ to find out what format they truly are, and in some cases, which version. I’ve seen cases from some of our customers where CAD files had, for whatever reason, been given the wrong extensions; once we learn...
Do Your Translations Look Like This?

Do Your Translations Look Like This?

Do your translations look like this? If so, you’ve got problems! This is the actual result of a translation by a software solution we will not name here – but you can imagine how dismayed the user was when they saw this output! The user contacted us and we set them up with a copy of TransMagic to solve their problem right away. Mis-translations can take many forms, from missing geometry (usually the most complex, organic geometry is missing, and prismatic geometry is retained), to missing details and PMI, to geometry that is there, however unusable; the screenshot above is simply the most outlandish and entertaining case of unusable geometry...
