Graduation project notes

• Drawing quantity must be sufficient: usually 3-5 A0 drawings, including assembly and part drawings
• Specifications must be complete: design calculations, specifications, task books all required
• 3D modeling: ability to use SolidWorks, UG and other 3D software is basic requirement
• Manufacturing process: design must consider manufacturing feasibility and cost

Frequently asked questions

How many drawings do mechanical graduation projects need?

Usually requires 3-5 A0 drawings, including assembly drawings, part drawings, electrical schematics. Specific requirements depend on school.

Can 3D modeling replace 2D drawings?

Many schools now accept 3D models replacing some 2D drawings, but calculations and verification in specifications cannot be omitted. Confirm with advisor in advance.

Which is easier, mechanical design or experimental topic?

Design topics have clearer workload but large calculation; experimental topics have less writing but require experiments. Choose based on your ability.
