So I found this helpful and useful video, absolutely loved it!
Only problem I've come across, is that in a new project of mine, I have a majestic staircase that curves with a semi-circular wall. The problem I keep hitting is how to curved the cad lines in cross section view to achieve the same result that our friend here achieved but curved?
This is what I came up with.
I drew the main staircase, turned off railings on right(wall) side. Used the copy/paste to duplicate the existing staircase in it's current position. Minimized it's width so it was tight to the wall. The main wainscoting back panel was created by increasing the stringer height, added a top hand rail and used the balusters to create the vertical stiles, I then duplicated this one and lowered the height a bit, replaced the top hand rail to get the pan
