Title Generating Coils in BRL-CAD.
Publication Date Apr 2012
Media Count 26p
Personal Author C. Yapp
Abstract Springs, shock absorbers, and other parts found in many modern mechanical systems can be described geometrically using a cylindrical coil. BRL- CAD is able to produce coils using the Constructive Solid Geometry (CSG) pipe primitive, but manually inserting enough pipe control points needed to create specific individual coils is a time-consuming process. The coil procedural tool automates most of this process by procedurally generating pipe primitives to describe coil shapes defined by high-level dimensional specifications.
