The main variation in sheet metal modeling techniques is when to let the 3-D CAD system know that the part is to be treated as sheet metal. With the 3-D CAD tool that I use most often, I have three ...

Anything that happens in real time is easier to conceptualise. This can be well illustrated by 3D games where users find simulation adventurous. It is the thrill of real-time effects that makes these ...

Below is the landing page. Computer Aided Design (CAD) tools can be categorized in a variety of different ways. At a high-level you can separate tools based on how they represent geometry, such as ...

Editor's Note: If you would like to see a video of the 3-D CAD model, click here. If you would like to download the 3-D CAD files, click here. The hair clippers shown in Figures 1a and 1b are of an ...

Geant4 offers constructive solid geometry (CSG) for modeling detector geometries, but representing intricate computer-aided design (CAD) structures can be cumbersome. This article presents a novel ...

Recent engineering software uses much more than Nurbs. Here is a guide to the best approach Most engineers are familiar with geometric modelers with their solids and surfaces and Nurbs-based curves.

Solid modeling is great for visualizing ideas but it's often misapplied in finite-element analysis. One of the latest methods of slashing development time is to use the 3D models that CAD users create ...
