AutoCAD Civil 3D :: Add Daylight Subassembly In Order To Grade Surface?
Oct 1, 2013
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.

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 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?

I am trying to model a DOT project in a fashion that allows a corridor surface creation for not only the finished surface, but also the datum surface. This is a machine control project currently under construction. One of the DOT's typical sections includes a shoulder subassembly with a grade break in it. This particular assembly varies in width at the grade break. I would like to have the option for a target width alignment at the grade break.
See attached sketch.

I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.

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 was wondering if there is a way that I can take an existing grade surface and apply a designed pond surface.
Right now I have the pond as a set of 3d Polylines in the proper geometry.
I want to place the pond into this surface and cut/fill at a 3:1 from that pond to the existing surface.

When we created our fist C3D template in 2007 it was possible to make a grading criteria that targeted a surface at a fixed distance. In other words, the slope was variable. Looking at it again in 2013 it appears it's not possible to creat a criteria like that. Am I missing something? Or was that option removed? .....perhaps because it was too unstable?

Cannot get corridor surface boundary from daylight points. Is there another way so that I do not have to trace the outer limits?

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.

I'm trying to create a proposed grade surface using the grading tools. I drew the outline boundaryof the proposed surface as a closed polyline then created a feature line from it and assigned different elevations to it. When I try to select the feature line in order to create the grading, I get "THIS FEATURE OVERLAPS ITSELF AND CANNOT BE GRADED". What could be a possible reason for this?

I'm having a random issue with the daylight ties lopes not tieing to the EG surface at all stations in the Corridor Section Editor. Some stations daylight fine. In plan view the daylight lines vary left & right as expected but don't display at all in Section Editor.
Some background info:2012 Civil 3D SP1 / 64 bit / WIN7Simple corridor used1 alignmentSame fg profileSame drefd EG surface (set all targets for daylight LT/RT)Only one assembly applied to entire corridor Attached are 2 captions of the issue I'm having which each have a cut & fill occurrence as well as a caption of the entire align. & corridor. I did try deleting corridor & recreating and even recreated a simpler assembly and still have the daylight issue in same areas of corridor.

Is there a better an easier way to change the order of input/output parameters in the subassembly that i've created in SAC 2013 than the one where you have to go into a XML-file in the PKT archive file?
I've created my subassembly and I want to control the order of parameters to have a flow similar to the actual workflow.

I can import my SA fine, but the problem is that the top of it needs to be cut off 1 m above the existing ground (which is already a surface in civil 3d). How do I setup the target surface so that when I import the SA into my drawing, I can link it to that surface and have it cut off 1 m above the surface?

I've to make a tunnel on my project. I get some subassembly on web but all the tunnel subassemblies have the target point on Width or Offset Target and Slop or Elevation Target. I don't know whats happens but only my region that owns the tunnel subassembly isn't recognizing on corridor, and isn't drawing on my sections too.

I have created a new assembly that uses a HMA dike rather than your typical curb but my surface always begins at the top of the HMA pavement rather than the top of the curb subassembly. See Picture. Where's the setting to fix this (is it a daylight setting) or it is a bigger problem in that I didn't create the subassembly or assembly correct to begin with?

I'm trying to create flexible model of a penstock with different ground surface elevation scenario.
In case if both top points of trench below or above EG, there will be cut/fill case to EG.
how to connect P1'/P2' and AX1/AX2 via EG? Basic link wouldn't work because it will be just a straight line.

When I use ImportSubassembly API to import my subassembly created by Autodesk Subassembly Composer into my civil project, it reports error-"eFilerError".
the code like this:
atcFile = @"D:9f92eaa4ef514ac982518852e1169932.atc";
itemId = "ab660722-c69d-4ade-b373-0e9f99c94e55";
SubassemblyCollection subassemblyCollection = cDoc.SubassemblyCollection;
ObjectId subassemblyId = subassemblyCollection.ImportSubassembly("TestSubassembly", atcFile, itemId, this.doc.Editor.GetPoint("Select import subAssembly location").Value);
However, it is OK if to import subassembly provided by Cilvil 3D.

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).
how to add this extera bench?

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 want to create a grade (without object grade) using a corridor. This is my assembly:
This only contains the sub assembly "DaylightBench" in the side right.
I have the alignment and profile. I have created the corridor.
red line= alignment
green line= feature line (code Intersecction) converted to polyline.
pink surface= surface (code TOP).
I have added a boundary for surface of type "add from polygon" and I have selected the closed polyline(green line).
However, the boundary seems doesn´t work.

I have a profile set up with a surface an alignment and a Water Main. I would like to place grade breaks (Using Profile labels) every 100' along the surface however the increment field isn't available for grade breaks. Weeding doesn't work because it needs to be exactly every 100' I was thinking of creating an expression for it however I still haven't reached that level of expertise.

I noticed a post a few years ago mentioning this function wasn't available then. Is it still not available? Is there a routine? A lisp? An expression that I can make to put a slope arrow inside every tin in my surface with a % grade?

Why do profile grade markers always reset in section views? This has to have been a wish list item. lsp or software to populate these? I heard in 2014 they still disappear.

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?
file can be .txt or .csv
