Line do not display in viewport created in paperspace and does not plot. Plot lineweights is checked in the plot manager.
Line weight is displayed in model space.
Line weights are defined "By Layer"
C3D generated profiles (left, right and bottom axis) display in model but not in Paperspace/viewport and do not plot.
I feel I have checked/set the "typical" settings both in autoCAD and C3D.
Still looking!
Thanks for your help
