EXTRACTED KNOWLEDGE / HOW-TO FROM CONVERSATION
QUESTION / CONTEXT: Context: I am building a Python + FreeCAD automation system. Goal: Drop a hand sketch image into my launcher and automatically generate a FreeCAD model. Current setup: I already have a working launcher called: freecad_ai_launcher.py This launcher currently works when I type a text description of the part. Example: "Create a 4 x 8 plate, 1/2 thick, 4 holes 1/2 diameter 1.25 from edges" The launcher then: → sends the prompt to AI → generates a FreeCAD macro → builds the CAD model automatically. So the text-to-CAD pi…
- *image → part spec JSON / structured prompt → your existing text-to-CAD pipeline
- Use a hybrid pipeline, not OCR alone:
- OpenCV preprocessing
- geometry detection
- dimension/text extraction
- local vision model interpretation
- rule-based reconciliation
- output a clean structured prompt
