AutoCAD 2013 and AutoCAD LT 2013 Essentials

Chapter 12

Keeping In Control with Constraints

Constraints are specific restrictions applied to objects that allow for design exploration while maintaining object shape and/or size within predefined limits. In this chapter, you will create three types of constraints in the AutoCAD® program: geometric, dimensional, and user-created. Once the design has been sufficiently constrained, you will make a host of geometric and dimensional changes simply by changing a single parameter.

• Working with geometric constraints
• Applying dimensional constraints and creating user parameters
• Constraining objects simultaneously with geometry and dimensions
• Making parametric changes to constrained objects
