Hi,
I'm completely new to Chief. I have drawn a polyline that marks the absolute maximum outside dimensions of the house. Now I want to draw some exterior walls of which the exterior side is exactly at that line. Note that in some places the exterior wall will not be on that line. The problem I'm having is that the snap aligns to the center of the wall. The result is that half of my wall is outside the polyline. How can I achieve my goal?
