I work on auto cad and I’m looking for some help to do with lisps. I'm a heating and plumbing engineer and I’m now working on designing underfloor heating systems. Rather than having to draw each run individually I was wondering if someone has written a lisp or someone knows some other way of creating the runs. I want to be able to type in the width & length of the external wall and then type in the total length of pipe. Then run the lisp so it plots on all the runs within the room. I would like to be able to state the start and end points of the run also each run needs to be filleted at the end. I’ve attach an example of what I need the final drawing to look like.
