# PO\_AlignInElevation

Align geometries (generic geometries or Pollination geometries) to elevation reference lines. Non-planar faces will be triangulated.

## Options

* **Threshold**

  A distance tolerance for how far away from each grid line that a vertex should be affected and snapped to. Default 10x of document tolerance.
* **Angle Tolerance**

  A degree number from 0 to 360 to filter each input geometry edges that have a angle difference from the grids. Input -1 to disable checking the angle tolerance. Default to the current document angle tolerance.
