Typically when using relative coordinates to draw lines / walls / shapes etc., the system will use the last indicated point where something was drawn as the reference point to begin the next entry. I have a hand made drawing of a floor plan for our house that I would like to have drawn in CAD using the program's wall tool. The drawing has the dimensions of all the interior walls written into it. What I would like to do once the exterior walls have been drawn is reference a specific corner of a exterior or interior wall and use this as the starting point to measure from to begin another wall. i.e., the first wall is 10ft from one interior corner, snap to this point to have the reference reset to 0,0 and then enter the dimensions 10,0 to begin the next wall and then enter the dimensions of how long the wall will be. Is this possible?
