For more information on all the UCS command's options, refer to AutoCAD's online help
system.
The more UCSs in your drawing, the more you need help managing them. AutoCAD of-
fers a handy dandy UCS dialog box for doing just that. Open it by clicking the dialog box
launcher (the little arrow at the right end of the panel label) on the Coordinates panel of
the View or Home tab, or simply type
UCSMAN
and press Enter. There are three tabs in
the UCS dialog box:
Named UCSs:
Lists World and other user coordinate systems. Set a UCS current
with the Set Current button, or right-click a UCS to rename or delete a named UCS.
(You can't rename or delete the World UCS.)
Orthographic UCSs:
Lists the six default orthographic coordinate systems (front
and back, left and right, top and bottom) relative to the WCS. These UCSs are auto-
matically created by AutoCAD and can't be deleted or renamed.
Settings:
Controls properties of both the UCS icon and the UCS itself.
After you define a UCS you think you might want to use again, you can save it in the UCS
dialog box. I explain how in the following steps, which you begin by creating a solid box.
1. Start a new 3D drawing selecting
acad3d.dwt
(or
acadiso3d.dwt
for the met-
ric crowd) for your template, and ensure the 3D Modeling workspace is current.
Refer to the steps in the “Entering the third dimension” section earlier in the
chapter if you need a refresher.
2. On the Modeling panel of the Home tab, click Box.
AutoCAD prompts:
Specify first corner or [Center]:
3. Type
0,0,0
and press Enter
.
AutoCAD anchors the first corner of the box at the origin of the WCS and prompts:
Specify other corner or [Cube/Length]:
4. Drag your crosshairs away from the first corner and click a point to set the
length and width of the box.
Exact distances don't matter in this example. And, hey! If you're working in metric,
you can drag and click to set a new corner too! AutoCAD prompts:
Specify height or [2Point]:
5. Drag the crosshairs upward from the second corner and click to set the height of
the box.
AutoCAD creates the 3D box and exits the command.
