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
Solids. Primitives and POLYSOLID
Editing. Rotate, mirror, align
Other. UCS, area, grip tool manipulation
TIP You can easily align the UCS with a plane on a solid model by turning on the
dynamic UCS feature and then using the UCS command to locate the origin on
that plane.
If Grid and Snap mode are turned on, they align temporarily to the dynamic
UCS. The limits of the grid display are set automatically.
You can temporarily turn off the dynamic UCS by pressing F6 or Shift+Z while
moving the pointer over a face.
NOTE The dynamic UCS is available only while a command is active.
To change the UCS dynamically
1 Start a command supported by dynamic UCS.
2 If necessary, click DUCS on the status bar to turn it on.
3 Move your pointer over the edge of a face on a solid model.
4 Complete the command.
