Like I said in a post way back early in this thread, I have been a draftsman with ten years using pencil, velum and cabled straight edge.
Then a drafting "machine" which had a clockable builder square on a jointed arm.
Since about 1992 it has been all 2D AutoCAD but no 3D.
Which makes me a dinosaur in the industry.
I have yet to see a 3D model drawing used by a fabricator or machinist to produce the actual parts or product.
3D modeling helps those that can not visualize what a part or assembly will look like when looking at 2D drawings.
