The prompt
Engineering Reconstruction Specification Objective Reconstruct a parametric 3D CAD model from the supplied PDF drawing. Geometry - Model the external blower geometry faithfully to the drawing. - Use the orthographic and isometric views. - Preserve all visible proportions. - Create separate solids: - Housing - Front cover - Impeller (simplified if needed) - Shaft - Motor - Feet - Electrical box - Inlet and outlet flanges Modeling strategy 1. Build housing using revolves/extrusions. 2. Create tangential outlet. 3. Create axial inlet. 4. Add mounting feet. 5. Model motor with cooling fins. 6. Add bolt holes from drawing. 7. Estimate missing dimensions while preserving proportions. Requirements - Fully parametric. - Solid B-Rep. - Export STEP AP214 and DXF 3D. - Metric units (mm). Estimated dimensions Estimate any dimension not explicitly shown while maintaining consistency.
