If it was just me doing the drawing I would agree. I could whip out a set of stairs in a few minutes. The problem is we have less than proficient engineers using DCs that I have built to construct models. I was trying to come up with something that they could use with minimal user input needed.
Would appear that “LADDERS” do not necessarily follow Stair Code Rulings or Standards. Might help to think of a Portable Ladder which follow “OSHA” (Labor Safety Standards) where the height from the Bottom Rung to the Finished floor is not necessarily constant with the the Rung-To-Rung distance. Ladders are indeed offered in Angle Variations between 60-75 Degrees.
