I apologize if the following is hard to visualize, but I'll do my best to explain the problem. I use AutoCAD in combination with pointclouds to make accurate drawings of building elevations (about 1/8th inch of tolerance across for the length of wall, window, etc.). I usually draw by placing a UCS on the face I'm drawing and turning on OSNAPZ and 3DOSNAP. This allows me to click the points on adjacent faces and have them projected onto my UCS making it easy to draw lots of elevations quickly. I can only do this however when an adjacent wall or face is 90 degrees relative to the face I'm trying to draw. If it is not 90 degrees, than the lines I draw cannot be accurately projected and I have to strain my eyes trying to make sure I click points exactly on the corner. I would like to project lines at angles other than 90 degrees if possible. For instance, imagine a pointcloud containing three walls in the shape of a triangle (not a right triangle). Is there a way I could accurately draw the outline of a wall by projecting lines created by clicking points from the other two walls? I feel like there should be someway to do this if I place a UCS on each walls' face and use the intersections of the XY planes, but don't know how...
