One of the advantages of using 2D drawings generated from a 3D model is that any changes made to the model mean that the drawing sheets are updated automatically. This is fine in theory.
My question is, how do people deal with drawing sheet revisions?
eg. I have 3D model A from which I generate views attached to sheets, with no revision. I can't update/amend 3D model A because these changes will propogate to the (non revised) sheets. This means that I have to copy Model A to create Model B which I then can update and use it's views to attached to rev. A drawings sheets.
Any thoughts/comments welcome.
