Description

Checks every solid body in the active CATPart for open (zero-volume or unresolvable) geometry using the SPA (Space Analysis) workbench. Each body is reported as OK, WARNING (zero or null volume), or ERROR (SPA measurement failed). Results are printed to the console with a summary.

Console Output

 Checking 3 solid body/bodies...

  Body                                 Status
  ------------------------------------ --------
  PartBody                             OK
  Support_Plate                        WARNING  (zero volume — may be open or empty)
  Mount_Bracket                        OK

 Summary: 2 OK  |  1 Warning  |  0 Error

Status Definitions

Status	Meaning
OK	Body has a positive, measurable volume
WARNING	SPA returned zero or null volume — body may be open, empty, or have conflicting geometry
ERROR	SPA could not measure the body — likely a regeneration error or unsupported body type

---

Notes

• Only top-level bodies in the part are checked — bodies inside geometric sets are not included
• WARNING does not necessarily mean the body is invalid; an empty body with no solids will also report WARNING
• For WARNING or ERROR bodies, use the CATIA Geometry Check tool for a detailed analysis
