Thank you for such a quick response, the detail and information was very helpful and Im exited to hear this design could work. I guess the only question I have now is at what point do you get an engineer involved?
If we consider the truss, do I need to design and finalize all the frame's plans before I can get the engineer to advise on the specifics of the truss and its joinery. Or should I draw the plans with approximate sizes pertaining to the truss and its associated members, allowing them to be altered and modified according to his results.
Im aware this might be a question for the engineer , I just want to know beforehand what to expect.
Cheers
