UCSicon command in AutoCAD – Control the display of the user coordinate system icon (UCS icon)

1. The way to call UCSicon command in AutoCAD

Scroll down menu Screen menu Type command
View » Display » UCS Icon » ON… TOOLS » Ucsicon Ddvpoint

UCSicon command controls the display of the user coordinate system icon (UCS icon). Icon of USC performs the direction of UCS axis and the origin position of current UCS.

To get visualization for the direction of current UCS, you can display USC icon. You can change the dimension, position and color of icon.

The different UCS icons are displayed in paper space and model space. In both cases, plus mark (+) appears at the origin of the icon when it is located at the origin of current UCS. W character appears on Y axis of WCS icon (World Coordinate System) when you use the icon of axis system similar to AutoCAD 2000.

A square appears at the origin of icon if you view UCS from above (plus direction of Z axis). The square does not appear if you view UCS from below, from the right.

With 3D UCS icon, the icon of Z axis is bold when you view from above XY plane and is dash when you view from below XY plane.

Broken pencil icon replaces for 2D UCS icon when the view direction is in the plane which is in parallel with XY plane of UCS. Broken pencil icon shows that the edge of XY plane is almost perpendicular with your view direction. This icon warns that you did not use the pointer to enter the coordinate.

3D UCS icon does not use the broken pencil icon.
