3D space

To show in examples the methods of manipulating 3D models in 3D space using tools from the UCS toolbars or from the command line.

So far in this book, when constructing 3D model drawings, they have been constructed on the AutoCAD 2007 coordinate system which is based upon three planes: the XY Plane – the screen of the computer; the XZ Plane at right angles to the XY Plane and as if coming towards the operator of the computer; and a third plane (YZ) is lying at right angles to both the other two planes (Fig. 17.1).
