This chapter includes all the commands used to obtain information from 3D objects, namely,
ID to get point coordinates and
MEASUREGEOM to get distances, perimeters, and other values. To check interferences,
INTERFERE is available, which also allows creating objects corresponding to the common volume, surface, or lines.
MASSPROP is the command used to obtain geometric or mass properties of solids.
In the next chapter, we will see how to obtain 2D drawings from 3D models.
