3D Design Philosophy

We develop all of our mechanical designs using 3D CAD software. The 3D data generated with our CAD software is the master document that is used for the fabrication of individual parts. All part features are included in the 3D database. Additionally, 3D assemblies have tolerance gaps between all of the parts to guarantee consistent assembly of the product, as part tolerances vary. The 2D drawings supplied with each part are supporting documents only. They provide information not included in the 3D data, such as material callouts, hardware callouts, finish, colors, revision control, inspection dimensions, etc. The parts cannot be fabricated from the 2D drawings alone because they are not fully dimensioned and detailed.
