Part CheckGeometry

Introduction
The check geometry tool allows you to verify if you have a valid solid

Usage
The tool is available in the Part workbench under Part menu or with the button in the Boolean toolbar. Select a part (beware to select the whole part and not just a face to check for valid solid) then launch the tool. You will see results in the Task panel.

Active extra BOP check
If you want to enable the extra BOP checks then follow these steps : Tools menu > Edit Parameters > Preferences > Mod > Part > CheckGeometry then in the right pane double click under Value for the RunBOPCheck parameter and set to true, then click Save to disk, close and restart. See the screenshot below.

If the parameter or folder does not exist, you can create it with a right click.
