CC3 does not have a fully-fledged 3D viewing engine. Perspectives Pro allows you to create floorplans from a fixed viewpoint which you can’t change. This view is isometric. It is not a true 3D editing package – in CAD terms it is "2½D." When you are adding solid entities such as rooms, solids, or walls, Perspectives works with 3D coordinates, hiding areas hidden from view and shading surfaces appropriately. However, once added, the entities do not have real 3D qualities – just imagine them as 2D drawings of 3D objects.
Perspectives symbols are restricted to four views – effectively we’ve had to produce 4 symbols for each object. For some symbols with infinite rotational symetry (an upright barrell) this makes no difference, for others such as beds, you are restricted to four angles when placing them. Just symbols have this particular limitation. Only a true 3D representation of every symbol would overcome this difficultly.
