AutoCAD Civil 3D :: Finding Drain Pipe Daylight Locations
Aug 21, 2013
I need to rough in a drainage pipe network that connects several structures around a site. The pipe inverts need to be 6.5' below the finished floor of each unit and must maintain a minimum 2% slope. The network needs an outfall at some undetermined point on the site. The pipes must follow some existing roads, so they are not interconnected directly to each structure.
How can I go about determining the potential outfall locations?
I've attached an image of a storm drain invert label for a storm drain profile. As you can see, the middle manhole has all three inflow pipes labeled. Is there a way to only label the inverts of the two pipes shown in the profile view?
Pipe network storm pipes: Fairly new to Civil3D and trying to set up parts list for the storm sewer pipe and would like the plan view to appear as it does currently. We use a polyline for centerline of pipe, similar to dashed linetype but line and space are the same, width set to pipe width.
I created pipe network for my storm drain project. I have located all the structures (manhole) to all angle point of my alignment as required. Also I "insert" manhole every 400' per local code requirements using the command "network layout tools; structures only. My problem is I couldn't find the tools how to trim the pipe that pass through the manhole. Please see attached pdf file.
One of the things I seem to struggle with is being able to depict a single pipe when it needs to be shown in one profile as a crossing pipe, and another profile where you you show a lenghwise slice through the pipe. I end up tracing the pipe with eliptical objects where I'm cutting across the pipe and setting up more for the lengthwise/sideview of the pipe. Is there a way to have two different styles for the same pipe, one for a cross cut and one for a lengthwise slice?
I have a corridor with conditional assembly for all 200 sections. One conditions which stretches 200 feet I can not get the daylight link to show in the sections.
Why 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.

I 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.
Is 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).
I'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?
I 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?
I have a list of offset distance from centerline on both sildes (left and right). I want to use this to create a polyline that represents the daylight. these offsets are taken from an old hardcopy drawings of cross-sections. is there any way to draw this polyline that follows the alignment?
I need to daylight to an offset, to create a clear zone/fall zone, but it must have a maximum slope of 6:1. If no daylight is found at the offset and maximum slope, then grade at the maximum slope to the offset then daylight to the target suface at a steeper slope.
I am trying to create in my sub assembly a daylight with a variable slope to a graded ditch then it back slopes to natural ground. (image attached). How can I do this in Civil 3d 2012?
I got this problem during creation of corridor surface boundaries. I would like to create a corridor datum surface using the daylight feature lines, automatically from the corridor surfaces-boundaries dialog box, but the daylight does not appear in the list.
I 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?
What is the best method of forcing a fill daylight using an assembly? Though I've played with several links, I'm not managing to get the results I desire.
Original intent was for daylight to have 4:1 slope and keep within the R/W. This causes some areas to hold water as shown circled in the image. I know I should be able to give it parameters or targets to avoid this.
Have a question regarding multiple daylight subassemblies, don't know if it is possible. So I have an assembly with a trench SA in cut condition and a project to surface in fill condition, I built the corridor with this assembly and most of things look fine. However, there is a short stretch (in cut condition) of the corridor that I would like to modify such that a trench is not provided. I know I can create a new assembly with my desire condition, then create a new region and drop that assembly there, but I am wondering if there any other way to achieve my goal without another assembly.
I have a corridor design and the corridor daylights very close to the pavement. I need to have rock from the EOP out beyond the daylight point to a 30' offset from the alignment. I need it to follow the EG and show a depth of 2' throughout.
I had to draw the rock shapes manually. But I'd like to figure out how to do it using the corridor if possible.
Please see the attached image. Everything beyond the daylight point was traced on top of the EG and then offset 2' to get the bottom.
I'm building up my assembly and I want to add a daylight sub-assembly in order to grade my proposed surface to the existing surface. Typically I would have a 1:3 slope up or down. I have choosen the DaylightGeneral for this and although there is quite a few parameters to play with, I'm only interested in the up/down slope but when I put anything sleeper than 1:4 it doesn't work, I get this red line and circle.
What approaches are available in civil 3D to takeoff the surface area of daylight slopes?Which do you recommend for given scenarios?
I tried compute materials but the volume report for cut and fill area is zero - so either I missed something or the compute materials for surface area does not work yet. Then, I tried the QTO manager and linked the corridor codes slope_link and daylight_fill to payitems. Slope_link has a QTO of 1,458,099M2 and daylight_fill has 913.39M2; I have more confidence in the daylight_fill takeoff.
