I have this rafter family that I modified from the dimensional lumber family out of revit. I added some voids in there for plumb cuts and an undercut out at the tail. I won't worry about the seat cut...
i can't get the 'undercut depth' dimension references in the right place. I want the reference line for the undercut depth to lock to the top of the plumb cut on the back end of the rafter. Notice I have a formula for the undercut depth to equal a length based off of the depth of the member itself. I cannot get the depth of the rafter itself, and the pitch and the undercut depth to all flex together. Could someone help me with this one. THanks.
