AutoCAD Civil 3D :: Transition Between Daylight Regions
Sep 12, 2013
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?

My road corridor regions can't be stretched using the region grips when 'geometry locking' is on, grip stretch works when i change the locking option to 'station locking', but it used to work fine also with geometry locking on.. It has happened somehow to all my files, so it seems to be caused by some application setting, the corridor regions can be stretched from grips fine on other pc's. (C3d 2013)

I am working on some car parks and am using corridors. There are some area's that consist of seperate regions to tie up corner areas and junctions etc.
I am using link codes to create hatch and would like to use non-solid hatch. But the hatch does not appear to line up properly between regions, as shown on the attached image.

As seen in the attachments, I am trying to crop an image. When I do, a black portion of the old photo still remains. This is for some pamphlets and having this black region around the photo looks odd. How to get rid of these black regions around a photo after cropping?

I have 5 intersections in a drawing and i try to update all the intersections regions one after the other with "Update Regions and Rebuild Corridor". The problem is that sending up to date some intersections send other intersections (previously updated) out of date. So i cannot have all my intersections updated. The only way i found to correct this is to "Update regions automatically". but this way i cannot make changes to regions manually.

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).
how to add this extera bench?

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 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

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 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?

I like to create a daylight assembly with following criterias
Fill/cut Condition
1. Target to surface 2.5% slope
2. If the surface is not met within 19 m from centreline, then till 19 m 2.5% slope and 33% slope afterwards till it hit the surface.

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.

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

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 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 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.

I've created a corridor with a Cul-de-sac. The problem is that the daylight lines targeted to the existing ground intersect at turn segments:
which results in defects of corridor surface:
I wonder if there's a way to overcome this.

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 have a fairly simple corridor, however, I had to modify the alignment, rebuild the corridor and resample cross-sections. Now my right daylight slope won't show up. It shows up in the section viewer, but not the cross-section. I had this problem once before and fixed it, but now I can't remember how I did...I have all targets, sections sampled match corridor sampling etc.

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.
