Here I am again with another issue...
Many years ago, when i was a young man (heck !!! 25 years ago !!!) i had made my first Lisp routine which would automate (or rather facilitate) making of a schematic section from an architectural plan.
It was a very long drawn program, which was done in stages and checked till it worked, and eventually it came out with a very rudimentary building section.
I stopped using that routine years ago (if you see the program you will understand why)
I am attaching it for whatever its worth... with the hope that someone has an updated quicker better way of making an architectural sectional drawing routine in this forum.
Its something all architects would require...
