I have been using inroads for a year and now just found out about using the multi-center curve command. I am modeling an urban t-intersection with sidewalks and c&g. In the intersection I am dropping a different template in that does not include the side walk and c&g. How is the best way to combine the minor and major road surfaces (ie where in the rad return do we allow one template to take over the other? This may be a function of intersection drainage. Any tips on modeling intersections using this method(multi-center curve command) would be gretly appreciated. I am going back and forth trying different things. I am using Inroads V8 XM.
Thanks

Hi,
There have been several posts over this issue recently. I suggest you do some research here.
However there are a few tips I can figure out right now:
1. Run RD for each corridor
2. use MCC comand for curb returns - it gives you nice horizontals and verticals alg which you can edit! For vertical take elevation from corridors you got in the first step.
3. In RD use piont controls with alg created with MCC. use these curb returns alg as a secondary alignments
4. In a simple T-intetersection is is enough to use point controls just for a sideroad.
5. For skewed intersections, you will have to combine point controls for sideroad and mainroad as well. Remember that for point controls you can use alg, features and corridor points.

Thanks for the advice and fast reply!!
For skewed intersections, anybody can kindly explain how to use the point controls to model it? I have got the curb returns using MCC, and also the main road and side road corridor.
In the image above, the edge of pavement (cyan arrow) is the origin of my template - the template defines only half the road width. The feature representing the 'centreline' of the template has a point control to make it follow the feature 'Edge of pavement_L' of the main road (outlined by the red line) and then a point control to follow the side road alignment (outline by yellow line).
In total, I created 4 corridors (main raod, side road, 2 fillet curves) and then combined them into one surface as seen above.

Thanks Mark, It works great!
