Collinear Constraint

Window | Constraints | Collinear

Moves the position of a line or arc so that its end vertex is exact in location to the vertex of the line to which it is being made coincident. The planar geometry of the moved object is maintained.

In the example below line 1 is connected to its associated lines by the Coincident constraint. Line 1 will be moved, along with its associated lines into the same linear plane as line 2.

Moving line 1 and its connected lines into the same linear plane as line 2
