How to Use ChatGPT as a Mechanical Design Engineer
Productivity & Automation | Practical Engineering Tips | CADDEX
Quick Summary: ChatGPT cannot output a native SolidWorks `.sldprt` or CATIA file directly. But when used as a calculation partner, macro writer, and documentation assistant, it saves hours of tedious desk work every week.
4 Practical Ways to Use ChatGPT in Design Work
1. Writing SolidWorks VBA & Python CAD Macros
Need to batch export 100 drawings to PDF or auto-rename custom configuration properties? Prompt ChatGPT: "Write a SolidWorks VBA macro that iterates through open drawing sheets and exports each to DXF with custom naming." It writes the script in seconds.
2. Quick Material Comparison
Unsure whether to use Al 6061-T6 or Al 7075 for an arm linkage under cyclic fatigue? Ask for a quick breakdown of yield strength, weldability, and raw material cost differences.
3. First-Pass Sizing Calculations
Use it to double-check formulas for beam deflection, bolt shear stress, or pneumatic cylinder bore sizing before entering parameters into CAD.
4. Engineering Change Order (ECO) Documentation
Draft clear, concise ECO and revision notes for your shop floor without wasting 30 minutes searching for words.
