====AR Marker Distance====

As well as setting the marker ID, you can also set the **AR Marker Distance** property.

This allows you to specify how far away (and in what direction) the actual asset is compared to the AR marker.

This is mostly designed for cases where you have several items in close proximity - this way you can place a **single** marker and not have to deal with placing several small markers on individual pieces of equipment.

If //every// asset that shares an AR marker ID has the //AR Marker Distance// property, then ARDI-AR will display a set of arrows instead of a list of assets. Each arrow will point to the **actual location of the asset**.

This means that an AR users coming up to the marker will be able to see which asset is which, then touch the item they want to find out about. 

===Property Order===

There are four parts of the AR Marker Distance property.

**Marker size**, **horizontal distance**, **vertical distance**, and **depth**.

These are normally specified in millimeters, but can actually be expressed in any measurements you like, as long as they are consistent with each-other (ie. if you are using inches, ensure //every// AR marker distance property is in inches).

Normally, positive numbers move //right//, //up// and //forwards//. Negative numbers move //left//, //down// and //backwards//.

So an asset with an AR marker distance of '25, 50, 0 0' is 50mm to the **right** of a 25mm-wide marker. 

An asset with an AR marker distance of '50, -100, -100, 0' is 100mm to the **left** and 100mm **down** from a 50mm-wide marker.
