losing superelevation data when editing an alignment.

[adsylva]

I have an alignment I need to edit that has a reverse curve.  The first curve was made with the "Floating Curve (from entity, radius, through point)"  and the second with "Free Curve Fillet (between two entities, radius)"

When I delete one or both curves i lose all the superelevation data beyond the editing location due to the temporary spit in the alignment.  The superelevation data is all manual.  This is a trail and the super is based on drainage not curves.

Any ideas on how to edit the alignment with a temporary split and not lose the superelevation data?  I have not found a way yet to remove the reverse curves and not have a temporary gap.

Thanks,

Andrew

An interesting problem.  I think I have a solution but it's kind of kludgy.  What I did was to first make sure that all of the manual superelevation stations were associated with the first curve in the alignment, upstream of the floating and free curve. 

I then edited the alignment and added a dummy tangent between the two existing lines.  When I delete the floating and free curves in the middle of the alignment the software uses the dummy line instead.

Can you export the superelevation data to a file before you edit the curve, then edit the curve, then import the superelevation data back?

Now I'm back on this problem.  Yesterday I decided to write a c# program to export and import superelevation data to a txt file.   I remove all critical stations except for beginning and end.  Then I add them back as manual stations in the nearest superelevation curve and finally adjust the supers for the begining and end accordingly.  Works like a charm so far.
