Default UI Menu: Modify/Modify 3D Objects/3D Boolean Operations/3D Add

Ribbon UI Menu:

Combines two or more 3D objects into one object. Any overlapping volume is removed. Select two objects to combine, and the second object is joined to the first object. Selection order is important, because the new object will have all the properties of the first object selected, such as layer and material.

The resulting object is one object. You can verify this by selecting the object.

The selected objects do not have to overlap. If you combine non-overlapping objects, they will still be combined into one object.

To select multiple objects hold down the shift key while selecting, then select Finish Selection from the local menu.

Note: Boolean operations can use multi-select modes to select objects as components for operations.
