Controls the visibility, placement, appearance, and selectability of the UCS icon.
Note By default, the Coordinates panel is hidden in the Drafting & Annotation workspace. To display the Coordinates panel, click the View tab, then right-click and choose Show Panels, and then click Coordinates. In 3D workspaces (not available in AutoCAD LT), the Coordinates panel is on the Home tab.
Summary
The UCS icon indicates the location and orientation of the current UCS. You can manipulate the UCS icon using grips. This is controlled by the UCSSELECTMODE system variable.
Note If the location of the UCS origin is not visible in a viewport, the UCS icon is displayed in the lower-left corner of the viewport instead.
Different user coordinate system icons are displayed in paper space and model space. In model space, you can choose between 2D and 3D icon display styles (see the Properties option):
- 2D. The letter W appears in the Y portion of the icon if the UCS is coincident with the WCS (World Coordinate System). If the UCS is rotated so that the Z axis lies in a plane parallel to the viewing plane—that is, if the XY plane is edge-on to the viewer—the 2D UCS icon is replaced by a broken pencil icon.
- 3D. A square is displayed in the XY plane at the origin if the current UCS is coincident with the WCS, and you are viewing the UCS from above (the positive Z direction). The square is missing if you are viewing the UCS from below. The Z axis is solid when viewed from above the XY plane and dashed when viewed from below the XY plane.
The following examples display two 3D UCS icons viewed in model space and a UCS icon viewed in a paper space layout.
