I have a main road corridor and a small access road corridor that intersects the main road. I don't want the intersection to have curb returns because I just want the access road to act as a driveway enterance (main road curb will run straight through and just get depressed at the access road enterance). However, I want the daylighting for the main corridor and the access road corridor to match up at this intersection and I'm not sure how to do this.
Solved! Go to Solution.
The zero contour on a Volume Tin surface is the intersection of those two surfaces. Create the vol tin between the two cor srf's and extract the zero contour. Use the zero contour to create outer boundaries for each surface and they sould meet up nicely.
There aren't a whole lot of good solutions if you want to create a corner in your corridor daylighting. One method I've seen is to omit the corridor daylights in this section, then extract the teaturelines from the two road edges and use them to build a grading object at the corner.

Sorry but I have been quite busy this week. I agree with Steve that there is no good way to clean these areas up and I use a bunch of different methods similar to the gradings Steve recommends. In a best case scenario I will simply omit one of the daylight links, extract the one that remains as a feature line, and let the other corridor target the fline in that area. I may also omit both daylight links in the conflicting region and just make a small surface from a few feature lines extracted from the corridor.
Searching you tube for intersection tutorials will show you a number of ways to create, manage and clean up these areas.
One technique that can be used in these scenarios is to work with merged surfaces as targets. So for this case you could first create a surface from the driveway corridor which has the radii and daylighting. Then create an intermediate surface by pasting the EG then the driveway. Use that intermediate surface as the target for the main road and it should blend the daylighting perfectly.
P.S. If the main road has ditches you might want to reverse the order of merging. Paste the main road into the intermediate surface and use that as a target for the driveway. Then the driveway will daylight to the main road ditches.
At the end of the day, this is still just an intersection. Just use appropriate assemblies for the curb return baselines.
Like one with no curb and just a support shoulder and a daylight subassembly.
