Moving the Origin

As previously stated in Lesson 9, the ORIGIN is where the X, Y, and Z-axes intersect. The Origin's (0,0,0) default location is in the lower left-hand corner of the drawing area. But you can move the Origin anywhere on the screen using the UCS command. (The default location is designated as the "World" option or WCS. When it is moved it is UCS, User Coordinate System.)

You may move the Origin many times while creating a drawing. This is not difficult and will make it much easier to draw objects in specific locations.

Refer to the examples on the next page.

1. Select one of following:

   • Ribbon = View tab / Coordinates panel /

   • Keyboard = ucs

2. Specify origin of UCS or [Face/NAmed/OBject/Previous/View/World/X/Y/Z/ZAxis]:_o

3. Specify new origin <0,0,0>: type coordinates or use the cursor to place new Origin location.
