Autocad Section Property Calculation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Make sure the centroid of the section is 0,0 if you want the I values to be
correct. 
Run it once. See what the centroid values are and move the section centroid
to 0,0.
Recheck it. If the centroid value is now 0,0 then the I values should be
correct. It has worked great everytime I have used it.
