An equal constraint forces two lines or polyline segments to maintain equal lengths or arcs.
In the example below, an equal constraint has been applied to the triangle on the left. The result is the block definition on the right, where the constrained lines in the triangle are equal to each other.
Manipulate an Equal Constraint
When you manipulate a block with an equal constraint applied, the constrained objects will remain equal.
In the example below, two lines in the polygon on the left have an equal constraint applied. The geometry of the polygon on the right has been changed, but the constrained lines remain equal in length.
