Check

The Check command in Rhinoceros 3D evaluates selected objects for errors in their data structure and generates a detailed report to help diagnose potential geometry issues.

How It Works:

1. Activate the Command: Type Check in the command line or select it from the Analyze > Diagnostics menu.

2. Select Objects: Choose the objects you want to analyze.

3. Review the Report: Rhino generates a detailed report, listing any errors or irregularities in the selected objects' data structure.

Purpose: This command is used to ensure the integrity of model geometry, making it easier to identify and troubleshoot problematic objects.
