# Digital Caliper

The digital caliper allows users in VR to measure objects in their virtual space. This feature is VR exclusive. To add a digital caliper to your experience, you can simply drag and drop the 'Digital Caliper' virtual object into the experience.

While the user is holding the caliper in VR, they can use the joystick to move the caliper jaw up or down. The jaw will stop moving if it is touching something. The holder can switch between 'Millimeters' and 'Inches' by pressing the trigger button while holding the caliper.
