construction drawings

[expetroman]

Hi, Can anyone tell me where to find inexpensive duct & piping layout software. I would like to create drawings for permits but do not have resources for cad programs. I am new to my own business and could use any help I get. Thank You

Might not be 100% what you're looking for, but there might be something you could use here..

Well you could draw them by hand.

Some of the subcontractors here use vectorworks it is cheaper than AutoCAD
