LinkSlopesBetweenPoints

Sometimes you want to do stuff in Civil 3D that isn’t readily apparent how to accomplish. One case where I’ve seen often is where you know where your daylight line is going to be, but don’t know where your HP should be located at. The image below is one such instance. I know where I want to daylight at, the TOP of Existing Slope Feature Line, and I know I want to have it slope towards my ditch at 2% and then down to the left flow path at 2:1.

In order to get this to work I’ll want to use the LinkSlopeBetweenPoints, a marked point, and a LinkWidthAndSlope.

Make sure to add the MarkedPoint Before the LinkSlopeBetweenPoints.

Here are the values used. Make sure to use the same Marked Point value, in my case BottomLeft.

The set the LinkWidthAndSlope to the top of existing breakline for the elevation and horizontal target. You might need to play with the slopes since I didn’t check it for this post.
