A sample of the original blueprints.
Redrawing the blueprints in the Vellum 2D CAD program is seemingly a never ending task. Each new drawing references a specific page and assembly or GA drawings have been broken down to individual components. All bend allowances for any formed fitting has been calculated and included in the "flat pattern".
A picture is worth a thousand words. Most of the 4130 fittings have been imported into a 3D Modeling program, rotated for the best 3D view and saved here. Flat 2D blueprints are, 95% of the time, more than adequate to represent a part, but seeing it as intended, is something entirely different.
