You can move one or [[Image:Info_icon.png|40px]] Click here to learn more selected objects at a time among different block groups. The objects can be selected either in the project workspace, or their names can be selected from the navigation tree. Right click on the highlighted selection and select about '''Move To > Propagation >''' from the contextual menu[[Defining_Materials_in_EM. This opens up another sub-menu with a list of all the available block groups already defined in your EM.Terrano project. Select the desired block node, and all the selected objects will move to that block group. In the case of a multiple selection from the navigation tree using the keyboard's {{keyCube#Moving_Objects_among_Material_Groups |Shift}} key or {{key|Ctrl}} key, make sure that you continue to hold the keyboardMoving Objects among Material Groups]]''s {{key|Shift}} key or {{key|Ctrl}} key down while selecting the destination block group's name from the contextual menu.
{{Note|In a similar way, you can move one or more objects from an EM.Terrano block group to one of [[EM.Cube]]'s other modules, you can import external CAD models (such as STEP, IGES, STL models, etc. In this case, the sub-) only to [[menusCubeCAD]] of the '''Move To >''' item of the contextual menu will indicate all the . From [[EM.CubeCubeCAD]] modules that have valid groups for transfer of the selected objects. You , you can also then move one or more the imported objects from to [[EM.CubeIllumina]]'s other modules to a block group in EM.Terrano. }}
