The Bottom Line

Use parametric drawing tools. Parametric drawing tools enable you to create an assembly of objects that are linked to each other based on geometric or dimensional properties. With the parametric drawing tools, you can create a drawing that automatically adjusts the size of all its components when you change a single dimension.

Master It Name two examples given in the beginning of the chapter of a mechanical assembly that can be shown using parametric drawing tools.

Connect objects with geometric constraints. You can link objects together so that they maintain a particular orientation to each other.

Master It Name at least six of the geometric constraints available in AutoCAD.

Control sizes with dimensional constraints. Dimensional constraints, in conjunction with geometric constraints, let you apply dimensions to an assembly of objects to control the size of the assembly.
