A perpendicular constraint forces two lines or polyline segments to maintain a 90-degree angle to each other.
Apply a Perpendicular Constraint
In the example below, a perpendicular constraint has been applied to the two lines on the left. The result is the block definition on the right, where the lines are perpendicular to each other.
Manipulate a Perpendicular Constraint
When you manipulate a block with a perpendicular constraint applied, the specified lines will always remain perpendicular to each other.
In the example below, a perpendicular constraint has been applied to one point on the octagon on the left. The geometry of the octagon on the right has been changed, but the constrained lines remain perpendicular to each other.
