Family End Point Lock

[Anonymous]

I'm getting an error creating the Revit family. In the intersection of two reference planes, I want to lock two lines from their points. Error: The Dimension would overconstrain the Sketch.

Its enough to a lock point from one line because the other line is joined.

but I can move  the non-locking line,

Move the reference planes and see if all lines follow.

How do you lock the end of a line to an intersection of two reference planes?
