How to check CAD Drawing?
1. understand the shape, structure and position of the parts.
2. look at the reference of the parts. The line of the axis, the line of the heart, the surface, etc.
3. look at important dimensions, accuracy, roughness, geometric tolerance, etc.
4. look at the technical requirements, materials, etc.
5. look at the three view, left view, right view, top view, section view, partial detail drawing, etc. to understand the outline structure and facilitate cutting.
6. focus on the tolerance precision requirements of machining, including roughness and so on.
7. technical requirements for heat treatment, hardness requirements and so on.
It need to pay a attention the tolerances, smoothness.
