Hi, I'm using the Vehicle Tracking wizard to produce a roundabout geometric design (which generates the roundabout crowns to the Stockdale method). I have followed the numerous tutorials for this which include the generation of the corridor and then surface for the roundabout. The roundabout geometry is created from the previously designed horizontal alignments and vertical profiles. The issue I am continually experiencing in exaggerated undulation in the surface & subsequent crown profiles as they are draped over the generated surface. I have no idea why or how these are being generated this way. I have searched online and emailed various Autodesk webcast presenters asking for guidance to no avail. If anyone on here could offer any guidance it would be greatly appreciated. I have attached a PDF showing the results of my corridor & surface which illustrate the effect i am describing.

Problem: We developed a proposed surface and generated contours from a 3D Corridor. The spot elevation labels were added along the corridor in each sheet file. When some of the spot elevations were changed, and some minor profile adjustments were made to the base line, the elevations on all the sheets changed. Many of these elevations no longer make sense (i.e. it now displays "???" or "-0.08" instead of "12.58"). What happened and how to fix?? Help!
I have built a corridor and corridor surface but I have a bowtie area (see attached pic) in the green circle. Can anyone give me a step by step on how to fix this? I tried removing the daylights in that area, but it still doesnt look right. I'm not so familiar with grading tools/groups so any help in that department would be appreciated. pics.docx
Mark_CV3D posted a topic in Civil 3D & LDDHello. My problem occurs when i have this railway assembly and want to create a surface from its bottom, (called "Datum" in english?). I have given the link at the bottom of the subbase the Code "Terrass" but it doesnt even show up when im in "corridor surfaces"-->add data--Specify code. None of the codes of the subbase shows up. What is wrong here? Im using civil 3d 2013
