I would like to use a dwg such as the one available here
http://www.tchweb.com/tchstore/produ...ble-Angle.html
to author structural shapes for use in the frame generator. What strategies should I employ to avoid problems with frame generator if I want to deign ata cases? As the simplest example, one of the first steps in structural shape authoring is selecting the default base point. I relize the word "default" probably means that I can change it when I generat ethe frame, but how should I make this selection? In the case of the site above, I assume I thould not use either of the "edges" but should I use the inner or outer "corner"? What additional issues do you suggest I pay particular attention to to aoid usage problems?
Many thanks in advance
Joe
