2. Check the strong rigidity of the main parts, and finally determine the shape and size of the component.

3. Determine the accuracy of the part, that is, give the technical requirements such as the dimensional tolerance and shape position tolerance of the part.

4. Check with other related components, and arrange for a review of whether the mutual relationship is proper.

5. Restore the assembly drawing of this part.
