Where can I get freeware to design timber roof trusses for residential buildings?
Working for a company that designs timber roof trusses, I am unaware of any freeware. As the design of roof trusses is complex, it may not look like it, I would strongly advise going to someone in the know. Freeware tends to lack the important part of the program, which ultimately means having to subscribe. Then there are no guarantees that it uses all the relevant criteria.
