Enter 3D CAD!

In the beginning of 3D CAD it was the same as what I described above. The draftsman did all of the design under the scrutiny of an engineer. An engineer was always involved with the design and was always the last word with approval.

I was introduce to 3D CAD in 1982 with Computervision CADDS 4. 3D CAD was in the realm of the draftsman. Engineers did not have time to learn 3D CAD. Draftsmen continued to do the design and creating drawings. But we did not create drawings we created what I have coined AID (Associated Information Documents). Yes they looked like drawings and functioned the same. They would be checked and corrected by revising the 3D model and AID.
