i have drawn a warren truss in ac9 and the truss is supposed to be 10-6 3/8 long constructed of 2x4's. i drew the truss and when i switched to 3-d it said "divide by zero at line 50 of file Warren Truss.gsm" asked me to stop or continue. then i continued and it said "library part was not converted properly(016)" again said, stop or continue. i continued. what does this mean and how can i correct it? the truss was drawn in as a solid piece with no webbing. somewhat like a solid beam.
