When should I expect a response...not in a hurry, just want to understand if you have all information necessary to complete calculations.
Expert:  StructuralEng replied 9 months ago.

I am looking at it right now.

Expert:  StructuralEng replied 9 months ago.

It's unclear from the description if you want just a ridge beam or if you want more beams parallel to the ridge, but not directly under it. Can you clarify or post a sketch?
