Add Intersection Points

This command adds points into lines or polylines where there are intersections. This can be useful for other commands such as Auto-Annotate. For example in the drawing shown, Add Intersection Points adds points to the boundary polyline where the lot lines intersect. Then Auto Annotate for the boundary polyline will label the boundary distance along each lot. This routine does not add intersection points on arcs.

This command can also be helpful for surface modeling with breakline polylines. At crossings, breakline polylines must have the same elevations for surface modeling. This command has an option to average the elevations of the polyline vertices at the crossing when the elevation difference is smaller than the specified tolerance.
