Is it possible/how to separate several "objects" imported from an stl file? I've imported some a model from an stl file. There are several "objects" (spatially separated), but Blender considers them as one object (due to the algorith of importing, I guess). Is there a simple way to separate those "objects" so that they become actually multiple Blender objects?
Select the object, enter edit mode with Tab key, select all with A and press P to separate, then choose whatever option suits your needs best. I am guessing you will probably want the loose parts one.
