Hi Jim,
I used "Find & Replace" to change all the 7" entries in the script to DTW, which is the new parameter Distance to wall. (Top entry in the parameters list in the objects settings). It has a minimum of 1 1/2" from the wall which puts the uprights directly against the wall. You'd probably never put the ladder that close and if you'd like to set the minimum at more than that it's an easy fix just let me know. I haven't done any extensive testing of it but it looks pretty straight forward and seems to work ok.(Don't delete the original just in case).
Doug
