# 3D pen If you use a VR headset with hand controllers, you can access the 3D pen tool from your wrist controls. However, a host can disable your ability to use the 3D pen in a Session. To activate your 3D pen, complete the following steps: 1. Raise and rotate your left hand as if to look at a wrist watch. 2. Use the touch cursor attached to your right hand to select the 3D pen icon. ![3D pen icon on wrist controls](/files/CyP7kfrhLX0RbzvhhEoH) The 3D pen and tool panel appear. To draw, hold down the trigger for the controller that the 3D pen is attached to. You can then move your controller in any direction in 3D space, and the 3D pen draws a line along that path. ## Tool panel features ![3D pen tool panel](/files/zF43PXnczBe7O2LeMk5g) To make a selection on the tool panel, use the tip of the 3D pen to tap.
