Stop letting ChatGPT hallucinate your CAD constraints and C++ logic. (Here is a strict prompt framework)
I’ve seen a lot of engineering students complaining that AI is useless for complex mechatronics projects because it just invents SolidWorks features, hallucinates Proteus components, or rewrites your entire ESP32 firmware when you just need to fix a single memory leak.
The problem isn't the AI; it's the prompt. You have to lock down its scope and treat it like a Junior Engineer, not a search engine.
Next time you have a broken script or a simulation error, use this exact prompt structure to force surgical debugging:
ROLE: You are a senior debugging engineer specializing in [MATLAB/C++/etc]. CONTEXT: [Paste error message and ONLY the 50 lines around the break] TASK: Identify the root cause. CONSTRAINTS: > * You may ONLY modify the lines directly causing the error.
- Do NOT change variable names or script structure.
- Do NOT rewrite the script.
- If you don't know the exact datasheet value, say "Verify with datasheet" — do not estimate. OUTPUT: > 1. Root Cause Diagnosis.
- The Fix (Show ONLY the before/after of the specific lines).
This forces the model to actually find the logic error instead of just guessing and rewriting your file.
I ended up building an offline HTML file for myself with 50+ of these strict engineering prompts (covering SolidWorks clearance reviews, thermodynamics derivations in LaTeX, and control loop debugging). If anyone wants the interactive library tool to use for their own projects, just drop a comment or shoot me a DM and I’ll send you the file.
