Easier Way?

Am I just missing something or do you always have to make a so many assemblies to model a corridor when the roadways have medians and are not symmetrical with 2 different widths of sidewalk?

I'm working on a roadway improvement project and it seems the further I go along trying to get the corridors built the more assemblies I need to build just for a couple feet of roadway so the corridor is accurate.

Is this just me or does everyone have to make so many assemblies and wrestle with the corridor builder to get this stuff to work?

Any chance we can get a Civil3D book for dummies out soon?

You can over-ride the subassembly paramaters on a per section basis using the View/Edit Corridor Sections tool. For example, you have the majority of your sidewalk 5' but in one small area, it is 6'. Simply over-ride the sidewalk width for the sections that it is 6'.

Does it remember these 'per section' overrides on future corridor regens?

That sounds good but it still leaves me creating a ton of assemblies to build the corridor sections that transition. I need ones that are pavement only, pavement with curb, shoulder, sidewalk, right in and out curb with and without curbing and sidewalks, and so on and so forth. I'm not even fussing yet about all these dang construction alignments I have to create along the places I need to transition and making sure the alignment goes in the correct direction with a profile for each one. Just seems to me this could be easier, or maybe they could explain how to do these various things more clearly or maybe I'm just not as smart as I thought I was..lol

You could create transition alignments where you need the inside and outside of sidewalk to be. You shouldn't have to create profiles for them as long as you use the urban sidewalk from the Imperial Structures tab. This sidewalk lets you set inside and outside 'boulevard' widths, which are basically the gap between back of curb and inside edge of sidewalk and outside edge of sidewalk and right of way line. The sidewalk width can be set to a specific width or you can override all of the parameters to target transition alignments.

An example. I had to design an intersection between a 60' road and a 50' road. Both roads have a 14.5' asphalt half section with a 2' curb and gutter. The 60' road has an 8.5' park strip and a 5' sidewalk. The 50' road has a 4.5' park strip and a 4' sidewalk. The curve radius at the back of curb and at the property line were different and start and end points did not line up. So, whew, this is getting long and complicated. I basically designed an alignment for both outside edge of walk and inside edge of walk. I then set my outside and inside edge of walk target alignments to override the sidewalk width.

If this is confusing I could send you some screen captures. I could post them here. I'm not sure if I can do that.

Anyway, I hope this wasn't too confusing.

Here are a couple of screen captures to look at. They should make my previous explanation more clear.
