CATIA Tutorials

CATIA Tutorials

Many web-based and video-based tutorials are of such poor quality (slow or missing pages, bad or unintelligible audio, incredibly slow pacing and over-reliance on slides) that they are unusable. Since a lot of our customers are CATIA users, we wanted to help clarify where the best CATIA tutorials are. If you know of good quality free or pro CATIA tutorial resources that are not listed here, please let us know via social@TransMagic.com and we will add them to this list. Free CATIA Tutorials Online CATIA V5k Tutorials – This free web-based tutorial resource has a lot of value and depth, being divided into categories of Part Design, Assembly Design,...
Which Geometric Modeling Kernel?

Which Geometric Modeling Kernel?

Since Geometric Modeling Kernels are a more precise format than STEP, and will often provide a superior translation, this listing will help you find which geometric modeling kernel powers the CAD application you need to communicate with. If you don’t have the ability to write the native CAD format, write to the geometric modeling kernel which powers the CAD application; geometric modeling kernels are more precisely written than neutral CAD formats, and give you the best chance of getting the cleanest, most accurate CAD geometry. For further information on when to use which CAD format (native, kernel or neutral), please see the CAD Format Ladder article....
Flatten Assembly and Convert to Assembly

Flatten Assembly and Convert to Assembly

Some of the tools in TransMagic can be lifesavers when you need them, and they often can work together like a Swiss army knife; two such tools are Flatten Assembly and Convert to Assembly. It is important to note that usually our customers either use one or the other of these tools to solve disparate problems. An application came up recently that allows us to use both of these tools together – here’s the workflow to go from an unusable, multibody DWG to a valid assembly file: DWG File Structure Before FlatteningFiles generated in AutoCAD Modelspace were imported into SOLIDWORKS, but the parts in the assembly weren’t showing up. When the DWG...
Split Body and Trim Body

Split Body and Trim Body

Split Body and Trim Body are features built into TransMagic Expert, which allow you to set a split-trim body, and use that body to affect a second body by spliting the body, or trimming the body. In the overview image at right, you can see an example of each; in the first example, a sphere is being used as a split body to generate edges where that that model intersects the larger cell phone case. In the second example, a cube is being used as a trim body to trim away that exact mass from the larger cell phone case.   Split Body Let’s say you want to capture the edges of a sphere (or any model) as it intersects a mobile phone case. Figure 1 shows an...
Bounding Box Calculations

Bounding Box Calculations

This article will describe how you can get an accurate minimal material estimate for your part using the Bounding Box tool. A Bounding Box is a ‘box’ that tightly encompasses your part geometry, giving you height, width and length values for the part. These dimensional values can be in any units you desire (this will be address later in the article). A typical application would be to estimate the minimum size of aluminum block you’d need to machine the part, or to estimate packaging needed for a given part. In addition to the ‘box’ shape, there is also a ‘bounding cylinder’ and a ‘bounding sphere’ which are...
