I've done a 3D frame in Inventor 2012 and after doing a 2D with a partlist chart I found differences between lengths. The length of the part list was the first one, the frame was modified and the partlist didnt update.
Found out that the d18 parameter was a fixed number. I managed to change it manually by changing the G_L parameter to d18 (Using PNU, image attached).
How can I set up my inventor to update the part length automatically?
