How to Open a JT File

How to Open a JT File

JT is an unusual CAD file format which regularly causes some confusion amongst CAD users. This article will overview the JT format, explain what makes this format so unique, and show how to open a JT file. The JT Format JT is a CAD file format provided by Siemens PLM Software. JT stands for Jupiter Tessellation, which points to the fact that JT files are tessellated, or polygonal – also known as Viz-Rep, for ‘Visual Representation’; but what’s interesting about JT files is that they can also contain precise, CAD Brep geometry. So to be clear, JT files can contain both polygonal and CAD geometry. But, but in our experience, JT files only contain CAD Brep...
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...
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 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 Non-Manifold Tools Show...

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 on. Data 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...
