Add a Symmetric Constraint |
|
A symmetric constraint forces two curves or points on an object to maintain symmetry about a selected line.
In the example below, a symmetric constraint has been applied to the two lines on the left. The result is the block definition on the right, where the lines are parallel to each other.
Manipulate a Symmetric Constraint
When you manipulate a block with a symmetric constraint applied, the constrained line’s angle, or constrained circle’s center point and radius, will remain symmetrical.
In the example below, the two outside edges of the polygon on the left have a symmetric constraint applied. The geometry of the polygon on the right has been changed, but the angles of the constrained edges remain symmetrical.
