Pgl constant elevation error

Your image didn't post, however, usually when you establish a Point Control linking a point to an alignment/profile and it doesn't conform it's due to the following:

The wrong point was selected to control.
The correct point is selected, but configured to the incorrect Horizontal/Vertical Alignment.
There's already an established control for the point that can not be overridden, usually due to station ranges configured on other point controls.
Point control is configured incorrectly due to needing both horizontal and vertical control and only 1 or the other is configured.

There could be more issues to note. Please send me your data set for review. I can probably locate the issue and let you know how to correct the issue.

Thank you,

I sent you the file via FDOT e-mail.

The profile that was controlling the left and right roadways was built off the centerline stationing in legacy GEOPAK and then imported to the design file with the alignment and stationing of the left and right PGL chains. Thus causing a slight difference in the elevations.

The rub is, you have to model it like you designed it. If you want both PGL's to follow the same profile, don't use PGL chains for anything other than horizontal control. Set the vertical point controls to the centerline alignment and profile.
