Feature Line Analysis - Change in grade

[Anonymous]

Would there be a way to to automate the analysis of feature lines or 3D polylines to place a block on all nodes where the change from incoming slope to the outgoing slope exceeds a specified value?

Yes.

For Feature Lines you'd use the methods found in this link:

For 3D Polylines I'd look at this post:

The code I posted in this forum post years ago may help:
