AutoCAD Civil 3D :: Daylight Slope Doesn't Show Up In Cross Sections

Nov 29, 2012

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.

AutoCAD Civil 3D :: Cut And Fill Slope Lines Won't Show Up In Cross-sections?

May 1, 2012

I have created a road for a pit mine (which is unlike roads I have designed in the past). The road switched back towards itself and I need to daylight the cut slopes to show the limits of the mine/road cut. However, my cut/fill lines are not showing up in my cross-sections, but the plan view is showing the limits of excavation.

I assume this is because my limits are intersecting, from each of the roads, the upper and the lower. How can I get around this, or why are my cross-section lines not showing?

AutoCAD Civil 3D :: Transition Between Subassemblies - Show Up In Cross Sections

Jun 25, 2012

Along my corridor I have different assemblies I used.  My sidewalk is curb side in some locations and in different locations there is a boulevard between the curb and sidewalk. I want to transition between these different  assemblies and I want that transition to show up in the cross sections I cut. Isn't there a way to tell Civil 3D to transition from one assembly to the next one as you could in Eagle Point?

AutoCAD Civil 3D :: Show Site Boundary On Multiple Cross Sections

Mar 19, 2012

I've got a series of cross sections that show an existing and proposed scenario and I need to show the location of the site boundary on the (multiple) sections.

I tried making a feature line from the site boundary but all the feature lines get projected - how can I just get the site boundary to be shown?

AutoCAD Civil 3D :: Cross Sections - Show Coordinates Of Main Parts

Oct 19, 2012

In a particular road project i need to show for all the cross sections, the coordinates (x,y) of the main points ( for example: daylight, etw and crown). I know that i can obtain it from reports->corridor  but as far as i know, i must edit in excel and paste each PK info next to the correspondant cross section.

Is there a way more automatic raher than copy paste the report list?

AutoCAD Civil 3D :: Daylight With Variable Slope

Nov 6, 2012

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.

AutoCAD Civil 3D :: Daylight To Surface Max Slope?

Apr 18, 2012

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?

AutoCAD Civil 3D :: Daylight To Offset With Maximum Slope?

Nov 7, 2012

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.

AutoCAD Civil 3D :: Test The Height Of Fill Slope Relative To Daylight Catch Point?

Sep 23, 2013

This seems like something that should be really easy but for the life of me I can't figure it out. I even started looking at using the Subassembly composer to create a custom SA but that seems like a ton of work so something that would seem to be a common problem.

I need to provide a v-ditch with 2:1 side slopes at the toe of a 2:1 fill slope. The flow line of the ditch should be 2 ft below the daylight point of the roadway pavement section.  

My problem is that the conditional subassembly seems to evaluate the height of fill directly beneath the attachment point of the conditional SA (pavement section daylight point in my case – “Daylight_Sub” Point code).  Instead I need it to evaluate the difference in elevation between the catch point of a 2:1 daylight fill slope and the conditional SA attachment point (Daylight_sub). If that difference is less than 2 feet, I need to provide the ditch, otherwise I can just use the daylight slope for the ditch foreslope and the existing surface for the backslope.

how to do this? Maybeits as easy as using a predefined daylight subassembly that I'm overlooking?

Here’s my current assembly attempt: 

And the resulting behavior. It is solving the 2nd fill condition when I would like it to solve the 1st fill condition:

AutoCAD Civil 3D :: Corridors / Sections & Slope Staking Reports

May 2, 2012

It’s been drilled into me that we should keep Civil 3D Objects as separate as we can in the design process, thus minimizing data loss in case of corruption (or other some such disaster).  So, our current workflow for our transportation projects is as follows:

Receive LandXML files of points, surface and existing CL alignment from surveyor.

Create a separate dwg for points which is then xref attached into our base model
Create dwg for EG surface, create dref
Create base model (existing conditions)
Create Roadway dwg, import LandXML of existing CL
Create design CL, dref
Create design profile, dref
Create Corridor dwg

We are now being asked to produce slope staking reports, which require a “live” corridor and a SLG.  Our current workflow doesn’t have both of these in the same drawing and since you can’t dref a corridor or a SLG, I'm forced to duplicate the SLG in the corridor dwg. Obviously copy/paste the SLG isn't an option either.  I tried that, then exploding them down to polylines and creating a new SLG from the polylines, select them all, yeah, random creation.

Is the intended workflow to have the design corridor, SLG and all the section views in one drawing?

I am adding on to an existing roadway. I want to match my exist.cross slope of the road way which will vary.

When I select to use the parameter reference LinkoffsetandSlope I get a slope, but it is in the wrong direction.The linkoffsetandslope is getting the grade from the existing CL of roadway and the existing edge of pavement.

AutoCAD Civil 3D :: Transitioning Between Assemblies Of Varying Cross Slope

Apr 5, 2011

how to create the transition portion of a corridor design where my road cross slope has to uniformly go from 3% to the right to 3% to the left.  I have the two regions set up, but I cannot get that "middle" or "connecting" region where the cross slope is "rotating" around my road profile center line to create this "+3% to -3%" transition.

I have been searching the internet and this forum, but cannot find a good explanation.  There is info out there about setting vertical offsets, but not sure how to do this so the cross slope is uniform all the way through this region (i.e., making sure that if the slope is 1.234% on the  right side, I will get 1.234% on the left side, etc.)

AutoCAD Civil 3D :: Cut / Fill From Cross Sections

Feb 25, 2013

I am working on a project for a park in which they are looking for a new access road and a parking lot.  I created the road and sections for it, now im looking to get material cut/fill from the sections.  I am having a tough time getting them to work.  The only thing I can get to work is if i created a volume surface comparing my eg to my fg surface.  That will give me a cut and fill material amount for my new road

What i am trying to get is the volume report for each sections, so i can get the cut/fill for each section.  I have followed the tutorials and tried everything, but nothing seems to work.  I created a surface from my corridor, and for some reason when i go to edit my materials, i cant add my proposed surface from my corridor to make the comparison from, and i think thats my problem.  Everytime i go to create my volume report, i get all 0's.

I am trying to set up portrait cross sections. I can get my views to create a grid and such that look correct, however when putting them on sheets, it rotate the border, but also the modelspace. Are there certain settings in the sheet creation or the dwt file I need to review to do portrait sections?

AutoCAD Civil 3D :: Xrefed Cross Sections

Feb 29, 2012

I have created a drawing called xsec. I xrefed the corridor drawing into it and data shortcut the alignments in as well. I created sample lines and cut my cross sections in the drawing. Everything at this point looks fine.

The problem happens when I create a new drawing and xref the xsec into it. In this new drawing only the right side of my cross sections is showing up. I want to use this drawing for my sheet set rather than have a bunch of tabs in the xsec drawing.

AutoCAD Civil 3D :: Adjust Superelevation / Cross Slope Transition On Intersection

Dec 19, 2013

In attached file the normal cross slope of secondary road(AB)  is 2% Right to left (Right higher). and for primary road cross slope is 2% Left to Right (Left higher). I produced this junction using intersection wizard and cross slope of secondary road only starts changing from start of curb return to match the long slope of primary road. Is this possible to increase this transition lentgh on secondary road to create smooth contours.

AutoCAD Civil 3D :: More Sampled Cross Sections Into Existing Ones?

Oct 10, 2012

I sampled my sections at 25 feet intervals, created my section view group and them plotted my cross section sheets. All look fine.My problem is that I need to include Station 21+17.40 and some other similar stations (in-between the 25 feet intervals) into my cross section sheets without deleting the existing Sample Line Group and Section View Group. Is there a way I can sample my desired additional sections and add them to the existing Sample Line Group and Section View Group and re-plotted my cross sections?

AutoCAD Civil 3D :: Cross Sections With A Surface Mask

Feb 4, 2013

We want to show two surfaces, an existing ground and a proposed ground, on a cross section. When the proposed ground meets up with existing ground, it would be nice for the line to end. With just existing ground continuing on. The surface is data referenced, and I would like to not break either of them. I thought adding a surface mask would cause the proposed surface to stop at the mask, but that doesn't appear to be the case.

AutoCAD Civil 3D :: Corridor Not Displaying On Cross Sections

Feb 28, 2013

I have a corridor with 2 intersections. It is more or less like a main road with an off-ramp and an on-ramp, both on the same side, with a big triangle shape island in between them. It involves an existing road widening and a connection with another existing road. Since it is a real scenario, the intersections aren't perfect 90 degrees nor the offsets are constant.

Create Western intersection and change offset and curb return targets to design aligments.Create Eastern intersection and change offset and curb return targets to design alignments.Model the corridor as per design requirements.Due to design constraints, I ended up removing both intersections. I didn't delete all the offset and curb return alignments although they're not targeted on any region. Deleting this alignments seems to make C3D crash. the actual intersection definition hasn't been removed, as I read on other threads. I kept on getting a couple of error messages on Panorama Event Viewer every time I rebuild the corridor.

So, the problem comes when I try to output the cross sections from this nice looking corridor. They all look fine until they reach the intersection area. From the intersection onwards, the corridor is not displayed on any cross section. Even way passed the western intersection.

Why the corridor doesn't display on the cross sections passed the deleted intersections?I have a bad feeling that removing the intersection wasn't a good idea in the first place but it's too late now.
