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® 2017 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.
In this chapter, you’ll learn to do the following:
- Work with geometric constraints
- Apply dimensional constraints
- Constrain objects simultaneously with geometry and dimensions
- Make parametric changes to constrained objects
