Version: 1.1
Document Type: Part
Iterates through all solid bodies in the active part and uses the CATIA SPA workbench to extract physical properties for each body. Results are exported to a CSV file next to the CATPart. Mass requires a material to be applied to the body — bodies without material will show mass as N/A.
| Requirement | Value |
|---|---|
| Python | >= 3.10 |
| pycatia | >= 0.8.3 |
| wxPython | Not required |
| Open document | Part |
- Open a CATPart document containing one or more solid bodies
- Optionally apply a material to each body to enable mass output
- Run the script — the CSV is written automatically
A CSV file named <PartName>_MassProperties.csv saved next to the CATPart, containing:
| Column | Description |
|---|---|
| Body | Name of the solid body |
| Mass_kg | Mass in kilograms (requires material) |
| Volume_mm3 | Volume in mm3 |
| Area_mm2 | Surface area in mm2 |
| CoG_X / Y / Z | Centre of gravity coordinates in mm |
| Ixx–Izz | Full ×ばつ3 inertia tensor (kg·mm2) |
- Mass is read from the product Analyze interface and requires a material with density to be applied
- Volume, area, CoG, and inertia do not require material
- Only solid bodies (PartBody and additional bodies) are processed — GSD geometric sets are not measured
- For measuring curve lengths and surface areas in GSD geometric sets use Export Curve Lengths Surface Areas To CSV
