# Rotation:Z Axis Specify

Rotation:Z Axis Specify command updates the CPlane by specifying new normal direciton, the current normal becomes the Y axis of the new CPlane.

- Define CPlane origin.
- Define Z Axis of CPlane.

## Step 1

While Specify Origin of CPlane prompt is displayed, specify a new origin of the CPlane.

## Step 2

While Specify Z-axis prompt is displayed, specify the new Z-axis(normal) of the new CPlane. The straight line from the origin specified in Step 1 to the point specified by this procedure will be Z-axis of the updated CPlane.

In the preview, the updated X, Y, and Z-axes are dynamically displayed according to the movement of the Mouse cursor.
