I am designing a sidewalk along a certain section of road in my town. Along this 800 LF of roadway, there are some sections that have curb and gutter and sidewalk and some that have neither. The roadway doesn't have a specific width; it varies from about 23.5 feet to 25 feet, edge of pavement to edge of pavement. I'm learning C3D 2010 by trial and error and lots of tutorials, but I haven't been able to find a tutorial that says how to model a sidewalk using the existing edge of pavement, only the centerline of the road. When I build my assemblies, will I need to do one for every section where the pavement width is different? Is there a better, easier way? One would think if you could build a corridor of the existing roadway, you could add on all sorts of stuff at the shoulders.
Thanks,
Pam
If all you are doing is the SW, think of the EOP as your roadway centerline, create an alignment for it >> eg & fg profiles, build your typical assembly. Create any control lines behind the curb you may want to finesse your design with. Create the corridor. Hope that helps

As you will find out, there are many ways to do the same task.
We are required to use the ROW centerline a lot of the time, but have a sidewalk job like yours that meanders around horizontally & vertically. We use a generic link that has a target for the sidewalk alignment & profile and then omit the link. See the image files for how we design them.
Thanks Bruce that will come in handi

Thanks, guys. The more methods to choose from, the better.
Now, on to the next step, once I figure out what that is. Oh, that's right. Driveway aprons and conditonal subassemblies. Civil 3D is turning out to be like putting together a 1000 piece puzzle and I don't have the picture on the box for reference.

It does start off that way, but the picture will become more clear the more you work with it.

You could also use an offset assembly for the sidewalk. This would allow the sidewalk to be stationed with the main alignment but built off the sidewalk alignment.
