on the ribbon.
Select the bottom right endpoint as the
origin; the message, “Specify point on
positive portion of Z-axis:” appears in the
command line. Also, a rubber band line
originating from the Z-axis is attached to the
pointer. Now, as you move the pointer, you
will notice that the Z-axis also moves.
Click the X option from the drop-down
shown in the above figure; the message,
“Specify rotation angle about X axis
:”appears in the command line. Also, a
rubber band line originating from the Y axis
is attached to the pointer.

specify the rotation angle. You can also
type-in the rotation angle in the dynamic
input or command line.
Similarly, you can rotate the UCS about the
Y and Z axes using the respective options
from the drop-down.
Example 6: (Creating the UCS by
specifying the Z-axis)
Using the Z-Axis Vector tool, you can create a UCS
by specifying its Z-axis.
Move the pointer and select the left
endpoint of the bottom edge as shown
below; the Z-axis will be aligned to the
bottom edge.
Example 7: (Creating UCS parallel to the
screen)
Using the View tool in the Coordinates panel, you
can create a UCS which is parallel to the screen.
