While the graphics came over great the dimensions and annotation left a lot to be desired. dwg and creating the 3D models.dxf was a bit of a faux translator since it was controlled by Autodesk. Use the drawing or utilize the 2D graphics provided by the. With electronic drawings, mostly from AutoCAD, we had two options. The 1990's - 3D CAD/CAM Moves to the PC!! This went on until 1995 with the introduction of solid modeling on the PC. I even was turning 3D wireframe into net surfaced parts. I had a great business turning drawings, manual or electronic, into 3D models. They were delivering the model along with the blueprint. The model now was delivered to manufacturing as an IGES file to use as a pattern. The 3D model could now be used for more than just basis for the drawing. It was around 1988 and surfacing was introduced to CADKEY, with an add-on called Fastsurf. They were plotted on vellum treated like drawings and released as blueprints. Actually, there was no name for them at the time, the Boeing draftsmen called them the "Flat File". There were no drawing conversions in the beginning, from about 1982 to 1988, due to the selling point of 3D CAD was faster drawings. There are very few people that know more about 3D CAD than I do.
