I've had a couple requests in the last week that I finish the Complex Truss module. The last time I worked in earnest on the complex roof module was about four years ago now. At that time my attempts to come up with a successful algorithm for laying out the trusses were not successful.
I thought I might revisit the topic again today with the additional interest shown. However after giving this some thought and creating some various tests I'm still not sure how to do it. Additionally even if I did create an algorithm it would need to be able to handle some interesting cases and do a number of checks.
Case in point look at the roof below, manually framed with simplified truss place holders. I've provided the rafter framing for comparison (automatically produced by the complex rafter module). This would be your typical complex roof, lots of roof planes and no apparent good method to truss it out. My problem is the red colored truss, it is too shallow in a couple spots.
I guess what I'm saying is that even if I create an algorithm which can get one to this point, I still don't even know if it is correct or will work. I would love to gather some feedback and thoughts on how to frame this out with trusses from those who are working or have worked in the industry.
