It’s not supposed to do 3D but was fine for the geometry of this dome. It looks like a repetitive geodesic structure but the designer wanted horizontal circular members at fixed heights so every level was different. Using LT to array the nodes then dimension member lengths/angles was easier than calculating them!
This is the first AutoCAD LT blog I’ve seen. It’s great the little brother has got a blog.
UPDATE 30-08-2007: Shaan found another LT blog. Apologies Kate, you’re RSS feed no 1031!
