I have to update some drawings right now, now these drawings were made in different times, i.e 2007/2009/2010 and such, when I try to update the materials inside the cutlist it doesn't let me do it. Who made the drawings wrote down the properties of the materials instead of link these to the actual material that the body is made of. When I try to delete it (so I can select the materials option from the dropdown menu) nothings happens. How can I solve this? Any suggestion?
Where was the information entered before? If it was in the cut list in the drawing, you should be able to re-assign the column, but if that doesn't work have you have you tried deleting the entire column and inserting another one that is linked to the Material property? Maybe that's what you tried, it's not clear (at least not to me) where or what you tried to delete.
