Constraints
Constraints are non–view-specific elements that can function independently of dimensions. Constraint
elements appear in all views in which their references are visible; dimensions are view specific. You can
modify and delete constraints independently of dimensions or remove them when you delete dimensions.
Constraints appear as green dashed lines in project views.
You create constraints by placing dimensions and locking them or by creating equality constraints.
Applying Constraints with Dimensions
When you place permanent dimensions, you can lock those dimensions. When you lock a dimension, you
create a constraint. A constraint (dashed green line) appears when you select its references, as shown in the
following image.
Constraint from locked dimensions
Many dimensions may correspond to the same constraint. For example, if you place a dimension between
2 walls and lock it, you have created a constraint. If you place another dimension between the same 2 walls
and lock it, no additional constraint is created.
Also see
Locking Permanent Dimensions
on page 222.
Equality Constraints
An equality constraint appears as an EQ symbol near the dimension line when you select a multi-segmented
dimension. If you select one of the references for the dimension line (such as a wall), the EQ symbol appears
with a dashed green line at the middle of the references.
