auto corridor feature line issue

[Anonymous]

C3d 2017 sp1.1

In an attempt to keep my minimum front draining lots at a minimum of 2.5% i created a "Min A" corridor that I extract auto corridor feature line from and add to my Overlot surface.  I am extracting the rear lot line feature line.  However, if I make a revision to the profiles I lose the auto corridor feature line and have to re-extract them and add them back to the surface (they seem to maintain if no revisions are made to the profile).  Is this the way they are intented to work or am I doning something wrong?  Thank you

Not sure if there is a bug at work here. I would first make sure that the feature lines tab of the corridor's properties dialog has the FLines you need checked/turned on and configured with the styles you need (check you code set too). If this was set up correct I would then use Recover on the base and source files, save and close. Then on the sheeet file. If this didn't solve the issue I would open a support case.
