Roundabout section view problem

[hkam111]

Hello everyone 

I have to create 4 roundabouts in a project and i am trying to use the vehicle tracking tool that civil 3d provides 

In the alignment it works fine and i have also created custom parts and added them to the subassambles that it has created 

now i want to create section views with some crucial points that are important but all the sections that i create are  not correct 

some examples 

the road is not evenly connected 

all the slopes should have been at 2% but they are not 

Its the first time using this feature in civil 3d and i want to know if its reliable 

i have attached the drawing id anyone wants to check it out

This looks like a fun project. What you have going here is very complex. Just took a quick look at one of the roads by Roundabout1 and it looks like there are three alignments very close to each other, all used in the Corridor with their own Regions.  I'm pretty sure they are not playing well together with that many baselines so close to each other relying on their own proposed profiles to interact.  Ideally you would want just one alignment on C/L and build your assembly off that.
