Civil 3D 2014 intersection corridor surfaces. Multiple baselines, boundaries, angled edges and Trimble Link

Two roads end in agle side by side to a third road.
I put them all in one corridor. I used three different baselines.

Trimble Link works only with corridor surfaces. So i had to create surfaces.
I tried both Feature Lines and Links.
In both cases surface was created only for the first baseline.
To create surface for the second one i had to uncheck the first baseline and so on.

Well, i did it this way.
I kept checked only the desired one. I created the surface. No matter Feature or Links the only way to get a correct boundary was to use the Interactive method.
I then tried to create a surface for another baseline keeping only this one checked. Everything went fine. I tried to revert to the previous one and everything got a mesh. I had to recreate the surface from scratch. Even worse the so painfull to create boundary.

So finally although the best way to create Cross Sections at intersections is to use a single Corridor with multiple baselines you cannot create multiple surfaces for Trimble Link and keep them correct.
You have to make seperate corridors.
Afterwards you have to create surfaces to use them in other corridor cross sections.

Finally i tried to create corridor surfaces using interactive boundaries. Ok, i did it. I exported the surface using Trimble Link. I loaded the DC file to Trimble GeoOffice. The angled part was wrong! In one case while importing the DC file i got a warning message. So angled corridor surface finish is possible. But it is useless for Trimble Link.

The whole idea i had was to create a total eg asfalt corridor surface and export it to Trimble. Bummer.
