When in a draw command, you align the UCS by moving your pointer over
an edge of a face rather than having to use the UCS command. After you finish
the command, the UCS returns to its previous location and orientation.
For example, you can use the dynamic UCS to create a rectangle on an angled
face of a solid model as shown in the illustration.
In the illustration on the left, the UCS is not aligned with the angled face.
Instead of relocating the UCS, you turn on the dynamic UCS on the status
bar or by pressing Fn-F6.
When you move the pointer completely over an edge as shown in the middle
illustration, the cursor changes to show the direction of the dynamic UCS
axes. You can then create objects on the angled face easily as shown in the
illustration on the right.
NOTE To display the XYZ labels on the cursor, right-click the DUCS button and
click Display Crosshair Labels.
The X axis of the dynamic UCS is located along an edge of the face and the
positive direction of the X axis always points toward the right half of the
screen. Only the front faces of a solid are detected by the dynamic UCS.
The types of commands that can use a dynamic UCS include the following:
Simple geometry. Line, polyline, rectangle, arc, circle
Text. Text, Multiline text, table
References. Insert, xref
