Important: This program provides preliminary drafting and calculation assistance only. It does not perform structural engineering, load analysis, connection design, or final code approval. Always verify rafter sizes, spans, cuts, loads, connections, manufacturer requirements, local building codes, and field conditions with qualified professionals and the applicable authority.
