INTERSECTION PROBLEM.

Please if some one can help us regarding attached file

Create alignments / feature lines representing back of footway etc then target with corridor model.

You can specify this when you create an intersection I think. Sorry I dont use the intersection command as it will not do what I need it to. I find it simpler to design using laignments the old way.

alimouds77, First off, welcome to the C3D discussion groups. It might help to clarify the result we are looking for. Is it necessary for the intersection to be a part of the corridor, or is a C3D surface the final outcome. If a proposed surface is all that is required than we can build the front of the sidewalk with the flow line at the radius. Secondly we can build the back of walk with a simply feature line connecting the back of walk with the row line. It other words while using the intersection routine don't specify sidewalk. Let it create a normal intersection as if there was no sidewalk. Then add the feature line to the surface as a break line to define the back of walk. again welcome to the DG and please come back often with questions and comments.

"Secondly we can build the back of walk with a simply feature line connecting the back of walk with the row line"

This will not be dynamically responsive to elevation changes of the intersection.

I would horizontally Target the 2D polyline linework of your sidewalks with the PCR Assemblies, or design and implement a correct PCR assembly for your conditions.
