Create finished grade profile based on high/low point station and elevation

[Anonymous]

Is there a method or separate software to create a finished grade profile based on high and low point stations and elevations? Adjusting the PVI's so that I match known high/low point stations and elevations is a chore.

Create a text file with the stations and elevations, then create profile from file.

Thanks for the quick reply. First, I never created a profile based on an external file. Very nice. However, in my case, that technique is used for known PVI elevations. I need to know of a method to modify the PVI's at vertical curves based on known high and low point elevations. Currently, once I set the PVI at a vertical curve, I get an high/low point station and elevation. Next, I manually (painstakingly) adjust the PVI to shift the high/low point to match my design high/low point station and elevation. I'm wondering if there is a way to input the station and elevation at the high/low points of the vertical curve as opposed to the PVI of the vertical curve.

I've never tried this, but there is an option to create vertical curves with a Passthrough point.  If you set that at your known location then you can move PVI points and adjust tangents etc. without moving that fixed passthrough location.

James,

did you ever figure this out. Having the same problem as you.
