Extracting STEP Geometry and Topology from a Solid Modeler: Parasolid-to-STEP,

Abstract

Parasolid is a commercial solid modeling software system It uses a manifold boundary representation. STEP is an emerging international Standard for the Exchange of Product Model Data. Included in STEP are proposed standards for Topology and Geometry (which provide the definitions of data types required for building boundary representations) and for physical files representing products. Parasolid-to-STEP is a software system written in the C programming language for translating a Parasolid format boundary representation file giving the shape of an object into a STEP format file describing the same shape. The system elementary curves (lines, circle, ellipse) and surfaces (plane, a sphere, cylinder, cone, torus).
