# Layer Distance Link

This iExpression calculates the distance between two 2d or 3d layers. It can also calculate the distance only in a particular direction.

##### First Layer (Name or Index)

is the name or index of the first of the two layers whose distance should be measured

##### Second Layer (Name or Index)

is the name or index of the second of the two layers whose distance should be measured

##### Compute

Determines whether the total distance or only the distance in a specific direction should be calculated.

##### Options

##### Allow Negative Values

Allows negative distances in order to distinguish different directions (only if distance is measured in x- or y-direction).

##### Scale

Allows to scale the computed distance value.

##### Enable Clipping

Clips the computed distance value such that it always stays between the given minimal and maximal distance.

##### Min Distance

If the computed distance is smaller than this value, this value will be returned.

##### Max Distance

If the computed distance is larger than this value, this value will be returned.
