From FreeCAD Documentation
- Press the
Create body button. The new body automatically becomes active.
- Double-click the Body in the Model tree or right-click and select Toggle active body to activate or deactivate a body. If another body is already active, it will be automatically deactivated.
- If a solid shape is selected first, a BaseFeature solid object is added to the Body; the BaseFeature is linked to the original solid shape. Accepted shapes can be an imported solid, or a solid made in any other FreeCAD workbench.
- In a new document, if a sketch is created from the PartDesign workbench toolbar, a new Body will be automatically created.
