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. 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.)

You may move the Origin many times while creating a drawing. This is not difficult and it will make it much easier to draw objects in specific locations. You will understand this better after completing 10A, 10B and 10C.

To MOVE the Origin

1. Select one of following:

   • TYPING = UCS M

   • PULLDOWNS = TOOLS / Move UCS

   • UCS II TOOLBAR =

   Command: _ucs
   Current ucs name: *World*
   Enter an option [New/Move/orthoGraphic/Prev/Restore/Save/Del/Apply/?/World]
   : _move

2. Specify new origin point or [Zdepth]<0,0,0>: type coordinate or use the cursor to place.

To RETURN the Origin to the default "World" location (the lower left corner):

1. Select one of the following:

   • TYPING = UCS W

   • PULLDOWNS = TOOLS / New UCS / World

   • UCS TOOLBAR =

DISPLAYING THE UCS ICON

The UCS icon is merely a drawing aid. You control how it is displayed. It can be visible (on) or invisible (off). It can move with the Origin or stay in the default location. You can even change it's appearance.
