Introduction

The Elevations on Poly tool enables the user to create Labels diplaying surface information on polyline vertices or picked points on a polyline. Each Label is stored in a list and can be individually styled according to user requirements.

The user can create a Label Set which will contain custom Label Styles and choose polyline objects.

In the example below, the user can create a Label Set called  'Lot Boundary', create/choose a Label Style which displays a marker/level at each vertex and reference Surfaces (NS = Natural Surface),

The user can choose from Labelling single picked points along the polyline or multiple points at each vertex.

**WARNING** Please note that EXPLODING polylines that have Labels will result in the permanent deletion of the Labels. The Label items will still remain listed in the Label Listing table but cannot be retrieved.
