=== Creating New Objects & Moving Them Around ===
[[Image:PO22(1).png|thumb|500px400px|Moving objects among different surface groups in EM.Illumina.]]
The objects that you draw in [[EM.Cube]]'s project workspace always belong to the "Active" surface group. By default, the last object group that you created remains active until you change it. The current active group is always listed in bold letters in the Navigation Tree. Any surface group can be made active by right clicking on its name in the Navigation Tree and selecting the '''Activate''' item of the contextual menu. If you start a new [[PO Module]] project and draw any object without having previously defined a surface group, a default PEC group is automatically created and added to the Navigation Tree to hold your new object.
