AutoCAD Civil 3D :: Creating A Ditch / Channel
May 11, 2012I'm trying to create a ditch / channel with a 4 foot wide base and 4:1 side slopes. I was going to create one using a feature line and inserting it to my design surface as a break line. Is there an easier way or better process I can use to create this?

Aug 21, 2012In highway construction, I usually check for lowest ditch elevation and see how the existing drainage flows. Typically one would create or specify in CL profile creation with a 15m offset right and left which would then generate existing CL and 15m offset profiles in profile view. However, the 15m offset profile might not represent the lowest point in the ditch as the lowest elevation offset distance varies along the highway.
My question: Is there a way in civil 3D profile creation where it can automatically trace the lowest elevation in the ditch and plot it in profile view?
AutoCAD Civil 3D :: Hydrographs - Calculation Of Basin Slope
Feb 22, 2012In hydrographs, SCS method, the basin slope is needed for the the calculation of the time of concentration. What is the method for the calculation for the basin slope ? If we have a 3D surface is there a tool in autocad to calculate that automatically?

Jul 24, 2013I had created a corridor using the attached assembly with conditional cut/fill and SlopeToSurface SA, the cut condition provides a ditch SA at cut only. Then had the Ditch Bottom Profile to follow a ditch profile that I created, and flows toward the increasing chainage. The horizontal offset and elevation of the ditch runs perfectly fine as desired, except between Sta. 0+465 (cut section) and Sta. 0+470 (fill section), where the ditch ties back to the edge of shoulder instead of going toward the outside (as shown in the blue lines).
My question is, do I need to make a transition between the cut and fill sections? If so how much effect and details is needed as I have a few other locations with the same issue.
AutoCAD Civil 3D :: Sump / Baffle Box In Drainage Ditch
Sep 6, 2013I'm trying to add a sump/baffle box to a drainage ditch. I'm taking this project over from someone else. They had created a surface. However, I'm confused about how the surface they made was created, but I have used it to give me a reference to were the sump is located on the profile view. (circled in blue). Currently that surface has wall that are 1.5' high with a bottom at -1.5'. I have drawn in the sump on the profile view (highlighted in yellow).
I have tried to start over by using breaklines. I have already created a standard breakline on the N and W side at 0. However, on the east side, how to create a breakline and keep the drainage basin grading to the exisitng drainage basin grade.
I have attached screen shots of the plan and profile view.

AutoCAD Civil 3D :: Subassembly Composer - Ditch Depth In Fill Condition
Feb 2, 2013I am trying to create a custom subassembly using SAC 2012 that will place a 1' deep ditch at the bottom of the slope in a fill condition. The trouble I am having is how to hold a consant 1' depth on the backslope and vary the foreslope since the daylight offset and elevation is variable depending on the slope of the existing ground. I need the attachment point to be the edge of the shoulder so it seems like a loop that varies the foreslope length would be required but loops are not allowed. I will also have the option to target a profile but I also need the ability to hold a constant ditch depth.
How to model this condition.
AutoCAD Civil 3D :: Create Side Ditch As Part Of Assembly But With Different Profile
Apr 10, 2012I am trying to create an assembly with a U channel (side ditch) that's top will follow the sidewalk it is next to but I need the profile of the U channel to be different than that of the roadway. Is there a way to create a custom subassembly part that will do this? Can I create a different allignment/profile for the bottom of the U channel that can then link to the other assembly?
The only other think I can think of is to use a dynamic block to add the U channel to my cross sections, but that will take a lot of time to do.
AutoCAD Civil 3D :: Ditch Subassembly In Corridor - Using Realistic Mode To View
Oct 18, 2013I'm using the Ditch subassembly in my corridor and am running into a problem when using realistic mode to view.
I've applied a render material to L3, L2 and L4 which is fine but when I assign a material to L1-L5 (i.e Top) it overdraws (or otherwise fails to display) the previously assigned materials for L2, L3 and L4.
If I set the Links L1-L5 (i.e. Top) to no display then L2, L3 and L4 display as expected but when IMX'd to Infraworks the existing terrain shows through at Links L1 and L5.
Is it possible to stop this from happening and have a seperate material for L1 and L5 whilst retaining L2,L3 & L5 materials?

AutoCAD Civil 3D :: Subassembly Composer - Variable Ditch Bottom With Slope And Delta Y
Oct 22, 2012I'm trying to build the ditch portion of my Subassembly backwards from an offset target "DitchOffset". The elevation of this point should be derived from a point that is using Slope and Delta Y from point "P12" (see attached). Must be at least 1m from the bottom of SubBase with a 5:1 slope.
The Ditch Bottom will be variable width. I'd like to be able to select my offset alignment for my ditch bottom. Have a link from this point extend at a slope to the Target Surface to complete the foreslope.
I can't quite picture how to complete the links from the DitchOffset point. This may be complicated but the diagram identify what I'm trying to do.

Apr 26, 2012Why I can't mirror the Daylight Inside ROW Subassembly? For some reason I can only place it on the right side of my assembly and in the subassembly properties there is no option to flip it to the left. In the Modify Subassembly section when it's selected the mirror option is greyed out.
What I am trying to accomplish seems simple enough:
I have a utility easement in a drainage ditch that is 30' wide with a sewer line designed down the center, we need a very simple 10' access road on the uphill side of sewer line with 4:1 Cut/Fill slopes on either side when possible, however when the 4:1 won't catch within the easement I need it to daylight within.
At first glance the Daylight Inside ROW seems to be the appropriate subassembly for this instance but I can't get it on the left side of my road.Is there a way to set up this parameter with a different subassembly because I can get other subassemblies on the either side just fine, for example, the Cut Slope Layout Mode subaasembly works but when I build my corridor with it the slopes tie outside of the easement in several locations.

AutoCAD Civil 3D :: Daylight With Variable Slope
Nov 6, 2012I wonder is it possible to have a daylight (or other function) that can give a different slope for datum and for the top. This would be useful for if you have different rules (e.g. because of geotech) with regard to temporary and permanent batter slopes.

Jun 14, 2012Is it possible to make a bench right before the daylight line meets the top surface (Original Ground)?
The Road prism is a tylical shape that has a u-shaped ditch on one side. The daylight line from the outside edge of the ditch follows a series of comlicated benches at set elevations and then terminates at OG with no trouble but I'm trying to get an additional bench to be generated before OG (see attached + yellow lines).
how to add this extera bench?
AutoCAD Civil 3D :: Daylight To Surface Max Slope?
Apr 18, 2012I'm modeling a simple corridor (12' lane 2%, 6' shoulder 6%, 4:1 to match EG). I used the "LinkSlopeToSurface" subassembly for the 4:1 to match the EG. Unfortunately our EG isn't always wide enough for the 4:1 slope to match it somewhere.
Is there an assembly that would use 4:1 as a standard daylight slope, but where necessary adjust the slope, max. 3.5:1, to match EG surface?
AutoCAD Civil 3D :: Transition Between Daylight Regions
Sep 12, 2013I am working on a project where some of the corridors require different daylight slopes. I need to transition between a region with 2:1 slope to a 10:1 slope. My local civ3d support said something about using grading tools to achive that.
What I understood was that my assemblies should not have any daylight sub-assembly and that i should grade the corridor and than add a transition zone between the different gradings. Did I understand correctly?

Feb 20, 2013I have been asked to put a feature (a diversion berm) at the daylight line of a roadway where cut conditions exist off the proposed shoulder. Because of the length of the project, it would be useful if this could be done automatically as part of the corridor, rather than creating a feature line from the daylight line and grading it separately.
Is there a way to continue an assembly past the initial daylight line and make it conditional to cut situations?
