This is a concept sketch for a MLD DuoMid bug net that has the support pole base offset 6" towards the door to provide room for a 30" wide nest, 3" from the back wall, and 3" from the pole. It is 86" long. The tub is 3" high. The net hangs 3" below the 54" peak, in a to-the-ground pitch.
This was done in Google Sketchup, which can automatically calculate the dimensional call-outs, essential for pattern layout.
Now that I've got the hang of it, using as-built dimensions and any floor configuration, a new version could be created in about 6 minutes. (Which is good, because I see a couple of errors.)
