I'm trying to use vertical regression to make a best fit vertical alignment that is close to the existing grade from a surveyed DTM. When I go to add vertical regression point, I have 3 options.
1) Horizontal regression points - If I use this, I get a point not found error as I didn't do a horizontal regression. We were provided a horizontal baseline just not vert.
2) Points - this allows you to pick cogo points one by one but I have 100's of points. There doesn't seem to be a way to pick multiples.
3) Alignments - this allows you to select your horizontal alignment and it will place a regression point at the cardinals in the horizontal but that is not refined enough as it's placing my points 100's of feet from each other.
If there was just a way to use more of the cogo points it would be fine.
Anyone know how to do this?
