Document Type: Part

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 negative volume), or ERROR (SPA measurement failed). Results are shown in a scrollable wx dialog with a summary.

Requirements

Requirement	Value
Python	>= 3.10
pycatia	>= 0.8.3
wxPython	Required
Open document	Part

---

Usage

1. Open a CATPart
2. Run the script
3. A scrollable results dialog appears showing each body's status and volume value

---

Dialog Output

The results dialog shows a table of all bodies with their volume and status, followed by a summary line. A monospace font is used for alignment. The dialog title indicates whether issues were found.

Status Definitions

Status	Meaning
OK	Body has a positive, measurable volume
WARNING	SPA returned zero or negative 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 solid 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
