● Three-dimensional models (3D drawings) cannot be marked with complete processing parameters like 2D engineering drawings, such as dimensions, tolerances, processing accuracy, datum, surface roughness and welding symbols, etc.

● Not all parts need to be processed by CNC or NC machine tools, but only engineering drawings need to be produced for traditional processing on ordinary machine tools.

● Three-dimensional models (3D drawings) still have local structures that cannot be expressed clearly, such as skew grooves and concave holes in parts. These local details can be expressed in 2D engineering drawings through views from different directions.

● Usually, when sending parts to third-party manufacturers for processing and production, engineering drawings are required.
