CAD Instructions

Solid Models and wire frame drawings are an enormous benefit for manufacturing, but we usually need a bit more information to get the job done,  In addition to your IGES-3D file, Solid Designer  or Pro Engineer file we need to know the non-geometry information as well. The best  way for this is a simple 2D drawing, often called a Critical-to-Function drawing.

The drawing doesn't need any dimensions, unless you have a special  
tolerance requirement.
 

Critical to Function Should Include
	Customer Part Number and Revision
	CAD File names
	An isometric view of the part
	Material Type
	Plating, Masking, Paint notes
	Special tolerances
	Hardware
	Assembly Instructions
	Bill of Materials for any assembly
	Quantity
	A Critical-to-Function drawing for a simple bracket may look something like this:
