# PairMaxDistance

Finds the maximum distance between edges in a pair. PairMaxDistance searches an array of edge pairs contained within an Edge data structure for the edge pair enclosing the largest arc length and returns the distance value.

## PairMaxDistance Inputs

Parameter | Description
Edges | A reference to a spreadsheet cell containing an Edge data structure, which must consist of multiple straight-line edges. The function expects the input Edge data structure to be sorted by pairs, such that evenly-indexed edges contain the first edge of an edge pair, and oddly-indexed edges contain the second edge of an edge pair.

## PairMaxDistance Outputs

Returns | A value representing the largest edge pair distance, or #ERR if any of the input parameters are invalid.
