=== Transferring Objects From Or To Other Modules ===
When you start You can move one or more selected objects at a new project in [[EMtime among different material groups.Cube]]'s [[Propagation Module]] and draw a solid object like a box The objects can be selected either in the project workspace without having defined any surface groups, it is assumed to or their names can be of selected from the impenetrable surface typenavigation tree. A default impenetrable surface group called Block_1 is automatically added to Right click on the Navigation Tree, which holds your newly drawn object. The default group has the material properties of "Brick" (ε<subhighlighted selection and select '''Move To >r</subFDTD > = 4''' from the contextual menu.4 and σ = 0.001 S/m.) This opens up another sub-menu with a dark brown color. You can continue drawing new objects in list of all the available material groups already defined in your [[EM.Tempo]] project workspace and adding them under this block node. Or you can define a new surface type with different properties. By defaultSelect the desired material node, and all the last surface selected objects will move to that material group . In the case of a multiple selection from the navigation tree using the keyboard's '''Shift Key''' or '''Ctrl Key''', make sure that was defined is you continue to hold the keyboard's ''Active'Shift Key''. The current active surface ' or '''Ctrl Key''' down while selecting the destination material group is always listed in bold letters in 's name from the Navigation Treecontextual menu. When you draw  In a new objectsimilar way, it is always inserted under the current active surface you can move one or more objects from an FDTD material groupto one of [[EM. Any surface group can be activated by right clicking its name in Cube]]'s other modules. In this case, the Navigation Tree and selecting sub-[[menus]] of the '''ActivateMove To >''' item of the contextual menuwill indicate all the [[EM.Cube]] modules that have valid groups for transfer of the selected objects. You can also move one or more objects from [[EM.Cube]]'s other modules to a material group in [[EM.Tempo]].  {{Note|You can import external objects only to '''[[CubeCAD]]'''. You need to move the imported objects form [[CubeCAD]] to [[EM.Tempo]] as described above.}}
You can move any object from its current surface group into any other available surface group. First select the object, then right click on its surface and select '''MoveTo > Propagation >'''. A submenu appears which lists all the available surface groups where you can transfer the selected object. You can also move objects among surface groups by selecting their names in the Navigation Tree and using the contextual menu. In a similar way, you can transfer objects from [[Propagation Module]] to [[EM.Cube]]'s other modules or vice versa. '''Keep in mind that all the external model files such as STEP, IGES, STL, etc. are first imported to [[EM.Cube]]'s [[CubeCAD]], from which you can transfer them to other modules.''' First select the object, then right click and select '''MoveTo >'''. In the submenu you will see a list of all the [[EM.Cube]] modules that have at least one available group where you can transfer your selected object. You can select multiple objects for transfer. When using the keyboard's '''Shift Key''' or '''Ctrl Key''' for multiple selection, make sure that those keys are held down, when you right click to access the contextual menu.
