AutoCAD allows for different preferences in the appearance and the position of the UCS icon. The position can be controlled using the button at the top-left corner of the Coordinates panel (with the little lamp icon). If you click on it you will find three different options.

As shown in the following figure, the first option will lock the UCS icon at the origin point of the drawing. The second option will always show the UCS icon at the bottom-left corner of the drawing area, and the last option is to hide the UCS icon. All of this is shown in the following figure:

In addition to controlling the position, the appearance of the UCS icon can also be adjusted using the UCS icon properties button found in the Coordinates panel. You can open the UCS icon window, which contains all the different options for controlling the UCS icon appearance, as shown in the following figure:

As shown in the following figure, the UCS icon window is divided into four sections:

At the top right, you will find a preview for the UCS icon according to the currently selected settings.

At the top left, you will find the UCS icon style section. Here, you can choose between two different UCS icon styles, as shown in the preceding figure – one is 2D and the other is a 3D icon. In addition to that, you can also control the Line width, as shown in the preceding figure, with settings ranging from 1 for the thinnest and 3 for the maximum width.

You can also control the UCS icon size in the drawing area using the slider on the UCS icon size section in the middle of the window, and finally, at the bottom you will find the UCS icon color section, where you can control the color for both the Model tab and the Layout tabs.

Now that we have seen how to control the UCS appearance, let's take a look at how to manipulate its position and orientation.
