摘要

As fabricators, our contribution to a project's design and 3-D CAD modeling is frequently limited to minor adjustments to improve the manufacturability of the item. One of our business objectives is to transform a CAD file into a deliverable manufactured item with minimum overhead. It is worth noting that we are also experts in the various manufacturing processes we operate; we recognize excellent manufacturing drawings and know exactly what is needed on them.Here's an industry secret: Great shop drawings don't always follow international drafting standards. For example, a shop drawing might include all dimensions required for forming a part for the benefit of press brake operators but substantially lack dimensions for all other features, the thought being that the holes and other features were produced with precision CNC technology and need not be inspected by humans. The point is that your organization can produce drawings for internal use that omit details that would be required on drawings intended for external distribution.
