Line Z @ 0
Simple Lisp Routine

Problem:

 

Users are Drawing Elevation drawings and using the plan drawings to project points from the plan to the elevation view.  The lines are being drawn at the elevation of the wall where they are being picked from and all the lines are at different elevations.


Solution:

Create a Routine to Draw "Lines" at an Elevation of 0.  You can lock on to any point and regardless of its "Z" elevation the line will be placed at 0.
