Coordinate system

dot2 3D geometric system lets you define and manipulate objects in 3D space. It features a geometric system architecture that defines the X-Y plane as the ground area with the height as Z -axis. All objects can be moved or rotated along the world- or their own object axis (if the object has been rotated) as described in chapter Stage View. You can switch between the world or object axis via a toolbar button or the keyboard as shown in the following list:

Operating Elements	Symbols in 3D View		Description
World axis or Ctrl + W			Objects can be moved along the world axis.
			Objects can be rotated along the world axis.
Object axis or Ctrl +O			Objects can be moved along the object axis.
			Objects can be rotated along the object axis.
