CONSTRAINTRELAX
Indicates whether constraints are enforced or relaxed when editing an object.
CONSTRAINTSOLVEMODE
Controls constraint behavior when applying or editing constraints.
DIMCONSTRAINTICON
Displays the lock icon next to the text for dimensional constraints.
DYNCONSTRAINTMODE
Displays hidden dimensional constraints when constrained objects are
selected.
PARAMETERCOPYMODE
Controls how constraints and referenced user parameters are handled when
constrained objects are copied between drawings, Model space and layouts,
and block definitions.
Constrain Objects Geometrically
Geometric constraints determine the relationships between 2D geometric
objects or points on objects relative to each other.
Overview of Geometric Constraints
You can specify geometric constraints between 2D objects or points on objects.
When you later edit the constrained geometry, the constraints are maintained.
Thus, using geometric constraints, you have a method of including design
requirements in your drawing.
For example, in the illustration below, the following constraints are applied
to the geometry.
■ Every endpoint is constrained to remain coincident with the endpoint of
every adjacent object—these constraints are displayed as small blue squares
■ The vertical lines are constrained to remain parallel with each other and
to remain equal to each other in length
■ The left vertical line is constrained to remain perpendicular to the
horizontal line
