==Create Breakline==
The "Create Breakline" tool will create a 2d_zsh breakline from a user input polyline and DEM. The user has a number of options, such as:
* Vertice placement along line - the user can specify additional intervals at which to extract elevations, or use only the line vertices
* Elevation extraction - extract straight from DEM, or use a statistical approach by looking at surrounding elevation values
The steps are:
* Specify the input polyline from which a breakline will be created from
* Select if the user only wants to extract points at a specified chainage (ignore line vertices) - otherwise points will be extracted a defined chainage and vertices
* Specify an interval at which to insert additional elevation extraction points along line - leave blank to output at line vertices only
* Specify the underlying DEM to use to for elevation extraction
* Specify a search radius for considering neighbouring elevation values if using a statistical approach to elevation extraction - leave blank to extract elevation from immediate cell
* Specify a statistical operation (must be coupled with a search radius). Options include:
** 'MAX'
** 'MIN'
** 'MEAN'
