I can only get a line to pickup the perpendicular intelli sketch relationship when drawing from a line or circle to another line. I can not start a line in space and pick up a perpendicular relationship to a line already drawn. Is this the way it works?
Jason, If you start the second line connected to the first, it will place the perpendicular constraint. If you start the second line away from the first and then attach the second to the first, it will not add the perpendicular constraint. This is a known issue. You can simply place the second line and then add the perpendicular constraint separately. regards, Rick B.
