Modify Constrained Objects with Editing Commands
You can use editing commands such as MOVE, COPY, ROTATE, SCALE, and
STRETCH to modify constrained geometry. The results maintain the constraints
applied to the objects.
NOTE
The TRIM, EXTEND, BREAK, and JOIN commands in some circumstances
can remove constraints.
For information about temporarily relaxing constraints, see Overview of
Constraints (page 248).
Constrain Distances and Angles between Ob-
jects
You can control distances or angles between 2D geometric objects or points
on objects applying dimensional constraints and specifying values. You can
also constrain geometry with variables and equations.
Overview of Dimensional Constraints
NOTE This topic has been included for AutoCAD-compatibility purposes only. In
AutoCAD LT, parametric drawing technology is limited to displaying and hiding
constraints, editing constrained geometry, and changing values at the Command
prompt.
Dimensional constraints control the size and proportions of a design. They
can constrain the following:
■
Distances between objects, or between points on objects
■ Angles between objects, or between points on objects
■ Sizes of arcs and circles
For example, the following illustration includes linear, aligned, angular, and
diameter constraints.
