Working with Geometric Constraints
Geometric constraints allow you to force specific 2D objects to be coincident, collinear, concentric, parallel, perpendicular, horizontal, vertical, tangent, smooth, and symmetric; to have equal lengths; or to be fixed in world space. In the following steps, you will assign sufficient geometric constraints to ensure that a rectangle will always remain square even when it is stretched:
AutoCAD LT cannot create constraints. However, LT users can view and edit constraints that were created in AutoCAD 2012. The sample files in this chapter use generic units so they can be used by both Imperial and metric users.
