Reduces vertices
Use the Reduces vertices function to simplify a polyline removing not significant vertexes, for example along an alignment.
Click Edit.
Click Reduce vertices.
Select the polyline.
Select the vertices reduction mode:
2D distance: vertices are removed if the 2D distance from point to alignment is smaller than entered value.
3D distance: vertices are removed if the 3D distance from point to alignment is smaller than entered value.
Confirm the selection.
