Creating a conditional sub assembly

Hey all...

 

I am at a crossroads with this corridor that I have to create in Civil 3D 2011, with a sub assembly that logically seems very simple...the conditions for daylight can be found in "Proposed Cross Section".  In short I have 4 fill conditions and 2 cut conditions, based on height above original ground...(there are additional requirements for guardrails and retaining walls but at this point i will settle for my slope reaching original ground)

 

Please, if anyone can assist me in finding a way to achieve the objective in the Proposed Cross Section without the anomalous results shown in "Sample Cross Sections", i would be really grateful.

 

Tim.

I think I have an assembly that will work for you, and has additional options that will allow for guardrail and walls later.

I used DaylightGeneral because it has built-in options for three cut and three fill slopes.  This allows me to have one conditional test for cut and satisfy both of your cut slope conditions.  I can also use two conditional fills, one for the three high fill conditions and another for the two lower ones.

What is your ditch foreslope requirement? Does it have to change with depth?

Yes,

 

the foreslope changes depending on the depth of cut at a at the foreslope.  However, a minimum 1m deep ditch, must be maintained.

I was wondering about that because your sketch wasn't clear on the ditch foreslope requirement.

 

This assembly arrangement keeps the ditch foreslope constant at 6:1.
