Would be interested in a strategy for a varying depth overlay, i.e. where the overlay assembly follows a centerline design profile rather than a pavement depth up from existing grade. Then the trick would be for the software to calculate the asphalt volume between the new top surface and the existing roadway surface.
View 8 RepliesI have a case with the Subassembly Composer where I have 3 varying depths. InsideLane, OutsideLane, and Shoulder. My Base shape below these 3 shapes will not setup properly. I understand why, it's because the varying depths will create a potential step up or down situation depending on the depth of the top 3 shapes. This prevents the definition of the Base Shape.
For the sake of quantities I'd like to create a Base Shape. I could create Base1 Base2 Base3 (one below Inside Lane, Outside Lane, and Shoulder). I would prefer not to for clarity purposes.
How could one approach this? I'm thinking that I need some conditional components to clean this up. I'm not a pro writing expressions. I basically need to define the links that define the varying depths between the top 3 depths. I need to create another point and link if the depths vary, and that link needs to be included within the shape definition for Base.
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.)
I need a sub assembly for a lane that you can specify varying cross fall. i.e it starts at -2.5% and ends at +2.5%.
View 3 Replies View RelatedSo I need an sub assembly similar to the SuperLayerVaryingWidth, but combined with BasicLane Transition sub. If the SuperLayerVaryingWidth sub would follow an ETW profile to set slope, then I would be set. Any tips on how to create this? I'm pretty rusty at building custom subs.
View 2 Replies View RelatedWe have just started using Civil 3D. I need to be able to create an assembly that will place a sidewalk at varying offsets (it is too random to make seperate assemblies). I have tried making an alignment of the back of the walk and attempted to use targets in the corridor to achieve this .
I will attempt to attach the DWG that I am working on. The Main alignment is PR-1 as is the corridor and the alignment that i need the back of the walk to follow is PR-1 BWR.
I have two surface ( OG surface and Gravel LIFT ), i need to have a table that Show me Depths range between those two surface with a color range, in a table and also to be able to see it in the the top surface.
Basically, In every Spot of the surface, need to represent a Depth range between the OG and the gravel surface by a specific Color.
For a surface: I would like to a boundary above a inlet point that is 3" deep.
I would like something like catchment area but the ability to specify a depth distance. Or specify a depth in the water shed analysis in the surface properties.
The only way I know to do what I want is user defined contours for each elevation. Is there a better way to do get a specific shed area for a depth?
I have a road that I am engineering and have set up my subassemblies using the daylight standard. But i would like to force a cut section until the fill gets to 2'. so that when i have 2" of fill it will still cut my ditches.

View 2 Replies View RelatedI'm currently setting up a band set and want to include a band "pipe invert depth" i.e. basically trench depth.
There are properites in the band label style composer for "pipe invert level" and for "cover" and for "pipe diameter" but not pipe invert depth.Is there a way to display the pipe invert depth relative to the reference (design) surface/alignment?
A secondary question to this is can you use basic arithmetic in the band label style composer? eg pipe cover + pipe diameter?
I was wondering if it was possible in c3d to label points in the fashion often used for nautical charts in which each sounding (elevation) point is labeled with the integer component of the number followed by the decimal as a subscript. For instance 7.3 metres depth would look like: 73
Also I've seen charts with depths as fathoms and feet so 64 feet depth would be 104.
I want to make a subassembly in SAC 2013 to change the slope after require depth,see attached example.

I know in Revit you can set the deep of view from the section line not sure if you can do anything like this in Civil3d.
Is there a way to find location/locations in profile view along profile with certain coverage/depth?
View 4 Replies View RelatedAny hydraflow calculates depth of flow and spread at sump inlets? Does it assume that the entire flow is coming from one direction (similar to an on-grade inlet)? Or does it make an assumption about how much flow is coming into both ends of the inlet?
View 4 Replies View RelatedI was recently trying to find the normal depth in a natural channel to use as an outfall water surface elevation in SSA. I double checked the normal depth calculations using the Express Add-On in Civil 3D. I found that while the normal depths correlated closely for channels with a single roughness coefficient, they varied considerably if a composite roughness coefficient was used for the left and right overbanks. This leads me to believe that composite roughnesses are being calculated incorrectly in SSA. I would like to use SSA for floodplain analysis, but am unwilling to do so until I have confidence in the calculations.

View 1 Replies View RelatedI 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.
I created a volume surface between the as-built and design surfaces, now I would like to show the points that display the cut/fill depths between these two surfaces. I tried modifying the surface property of that volume surface but doesn't seem to offer what I want.

Simple program that will adjust invert elevations of a pipe based on the cover depth.
I have a existing uitility maps that only label the the cover depths. I have to show these utility crossings in my profile views. I have different rules set up for various depths when laying out my crossing pipes in plan, but I need the ability to to edit the various cover depths more quickly. I am using Civil 3d 2012 only.
I am having a problem with an overlay and widening C3D 2012 project. The sub assembly I have chosen is processing with the corridor datum surface cutting into the existing road surface, as would happen with a “milling” section (which I don’t want), I need it to overlay onto the existing surface only, with a nominal minimum thickness of 4” . I think this sub assembly is drawing the datum surface from the datum point of the widening on one side to the datum point of the widening on the other side, not sampling the "bottom" of the overlay surface.
See attached screen shot. Also attached are screen shots for some of the sub assembly and corridor parameters for my current settings. I am using the “overlaywidenmatchslope1” and “basicsideslopecutditch” subassemblies.
I have tried changing the sample point offsets and the insert point offsets without fixing this problem. I have not added any additional alignments for saw-cutting yet as I am trying to keep it simple until I get the assembly to process correctly with a fixed width.
I looked at trying the “overlaywidenmatchslope2” subassembly, but it is for non-crowned roads and would not work for this project. Are some of my parameters wrong? Is there another subassembly that I should be using?
I have a project where I am removing existing asphalt pavement and overlaying new pavement. I am changing the existing profile and cross-slope to tie-in to the existing profile and cross-slope. know of a mill and overlay subassembly that will allow you to tie the edge to a profile or feature line?
View 9 Replies View RelatedI am trying to overlay a large area,I have a design profile grade that I must use. I need the new edge of the overlay pavement to be 2" above the existing as long as the pavement cross slope is between 1% to 1.5% . If the slope goes above or below the min or max I need it to take the min or max. If I use the overlaymillandlevel2 I am unable to get it to use the overlay thickness since i am using a profile.

I need to create a carriageway overlay corridor on and existing carriageway that has a curved surface and not a typical crossfall. I've tried the LaneParabolic assembly but it doesn't give me the control I need to target an alignment and profile.
View 8 Replies View RelatedI am overlaying and widening an existing road, however the assembly is not behaving as I would like it too. Here is the cross section below, the widening, overlay and day lighting portions appear correct, how the Datum surface is off.
DATUM SURFACE - The datum surface is not following the existing ground in between the two road widening pavement portions. You can see the datum surface as a red line connecting the two paved widening below the existing crown of the road. I would expect the datum surface to follow bottom links of the overlay as well up through the crown, but this is not the case.
EARTHWORKS CUT/FILL SURFACE - The earthworks surface shows that the area between the existing crown and the unexpected datum link is being calculated cut/fill (cut presumably) which it shouldn't be.
ASSEMBLY BEING USED: Perhaps I am misusing the subassemblies, or link codes need to be modified.
I'm looking to make an assembly to follow the crown of the existing roadway which is to be milled and overlayed. In addition to being milled and overlayed there will be a curb bumpout which will be full depth pavement. The roadway does not hold a constant crown at 2%, it varies which is why I would like it to mimic the existing roadway cross slope. What would be the best way to go about making an assembly to model this. I have attached an image so that you may get an idea of the situation. I have a curb gutter line which I would like the assembly to target in both width and elevation. The single slanted hatch is mill and overlay and the double slanted hatch is full depth pavement (widening).

I'm very new to Civil 3D.I've been given original topography in a .dwg file and a .csv file of the same topography after some dirt work.My problem is when I import the .csv file the points don't overlay the original topography.

I am in the process of transitioning from land desktop to Civil 3D. I design roads in steep terrain and sometimes need to have my catch (daylight) slopes change. So my question is, how do I change a daylight slope at a specified depth? For example, from the shoulder of the road I want a 3:1 fill slope to a depth of 10 feet than change to a 2:1 slope until it catches the existing surface. Can this be built into a subassembly such that if the fill is less than 10 feet it will daylight correctly at a 3:1 and if the depth is greater than 10 feet then it carries the 3:1 for 10 vertical feet and then changes to the 2:1 until it daylights?
