Introduction To Model Interrogation

Contents

Parasolid models can be used across the manufacturing process as definitive 3D representations, therefore Parasolid provides a comprehensive suite of functions that enable applications to query information about a given model. This volume explains how to use these functions to enquire about the topological and geometric information of a model and calculate the various mass properties of a model, such as area, volume, length, center of gravity and moment of inertia. It also explains how to detect clashing entities and how to test the validity of a body.

This volume contains the following chapters:

• Chapter 26, “Enquiry And Output Functions” describes the enquiry and output functions used in Parasolid
• Chapter 27, “Mass Properties” describes how to calculate the mass properties of an entity
• Chapter 28, “Calculating Minimum And Maximum Distance” describes how to calculate the distance between entities
• Chapter 29, “Clash Detection Of Bodies” describes how to detect clashes between bodies
• Chapter 30, “Checking” describes how to test the validity of a body.
