Add a Coincidence Constraint

You can set a pipe or duct on the same line as another pipe/duct or building component by binding them together using a coincidence constraint.

1. Select Constraints > Coincidence.
2. Select a line or a point (A).
3. Select another building component: a line or a point (B). The objects will be made coincident.
