How to modify a vertical complex geometry

Hi all,

I'm working on ORD 2019 update 1.

We have created a lot of horizontal and vertical complex alignment for a project.

Many corridor have been created based on these alignments.

Now the design criteria have changed and we need to modify those complex vertical.

We tried to drop the complex vertical( with drawing command), but then the rules get messed up.

We want basically to remove tangent and curves and add new ones in the complex without creating a new complex. Just want to modify the one we've already created.

So far we haven't find a simple way to do that. (it was so simple in SS2). Even with the table editor we can't delete existing tangent in the profile (or modify the lenght for that matter).

Don't want to start from scratch, we have to many manhours in this project already!

Any suggestion.
