False dormer sets are often used in the HUD/Modular housing industry to connect two building structures together at right angles or to add interest to a residence's elevation. They are referred to as "false" since they are added on top of a finished roof on site and are not truly "engineered" for any particular load. They are considered fully supported and decorative facade. The variables required to design a truss set of this type are quite extensive and productivity and response required an automated solution. These pages show the output of one such set run entirely from within AutoCad using Visual Lisp. I created this at Banks Lumber/Superior Truss. ALL the views, notes, plates, etc. are added or created AUTOMATICALLY when run: there have been NO manual edits.

In this challenge a building company makes several model homes with 4 different roof line and garage options requiring 16 different elevation sets. Their question was could I come up with a way to create their sale elevations without needing to create 16 separate drawings. Although I first considered using an exterior block as a reference for the walls, I finally decided to keep it all in one drawing file. The following was accomplished using different layers for the 4 roof and garage options and creating a paperspace layout with 16 viewports each. Each viewport then used different VPLAYER settings to create all the elevations for each garage option on a single page of a given roof line. Future plans include different siding options.
