You can use a Vicon Active Wand to set up your volume coordinate system quickly and easily (see [Set the volume origin](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556426/Set+up+the+volume#Setupthevolume-SetVolumeOrigin)). However, using a larger calibration object (for example, markers embedded in the volume floor and wall) can improve calibration stability and consistency over time.

You can create and export a custom calibration object from any object as described in [Create objects](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556808) and [Export an object as a VSK](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556903/Manage+objects#ExportObjAsVSK).

When you export the VSK, save it to your calibration objects folder. The default location is: *C:\Users\Public\Documents\Vicon\CalibrationObjects* 

You can use the custom calibration object to set the origin of your volume.

For detailed information on how to create and use a custom calibration object, see [Scale calibration and set a fixed origin](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556519).
