TABLE OF CONTENTS To show in examples the methods of manipulating 3D models in 3D space using tools from the UCS toolbars.
So far in this book, when constructing 3D model drawings, they have been constructed on the AutoCAD 2006 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) at right angles to both the other two planes (Fig. 17.1).
In earlier chapters in order to view 3D objects which have been constructed on these three planes or at other angles, we have used presets from the 3D Views sub-menu of the Views drop-down menu and have indicated other methods of rotating the model in 3D Space and placing the model in other viewing positions using the Vpoint Presets dialog.
| Note | The XY plane is the basic UCS plane, which in terms of the ucs is known as the *WORLD* plane. |
The UCS allows the operator to place the AutoCAD coordinate system in any position in 3D space using a variety of UCS tools (commands). Features of the UCS can be called either by entering ucs at the command line, or by selection from the Tools
