AutoCAD Civil 3D :: Corridor Generate Widening On The Curves
May 27, 2013
Althout I have created the widening on my aliment and used a designer critery on my corridor, I can't achieve that the corridor use the widenig on the curves.
I need that the corridor generate the widening on the curves, I can't stake the corridor without widening.
Please see attached.

I do a lot of visualization work I need a corridor top surface split by material FAST. before I used Corridor Solids but I don't have the extension in 2013. So I export to CivilView, so far so good, then attempt to roundtrip the mesh back in Civil3D and that is where things fall apart.
Export to DWG is not split by material
Export to 3DS results in a blank screen
Export to FBX comes in missing large chunks of mesh out of scale and in the wrong location

I have a corridor drawing with my corridor and have sample lines ever 25 feet. I would like to generate my sections in a seperate drawing. Is this possible?
(I am trying to keep different pieces to my project in different drawings.)

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?

Is it possible to make the widening get the exact offset to the spiral / clothoid. All I get is a linear line as shown in the picture.

I have created a widening then created an 11-foot offset from the widening for some reason I cannot create a 22-foot offset or an d11-foot from the first offset. I can go as high as 22.5 but no more. There are no curves in the alignment only linear tapers. why I cant get to 22-feet?

I've used the OverlayWidenMatchSlope1 subassembly to widen a new travel lane using the existing carriageway crossfall then I try to create another lane using the same assemble following the same slope but the insert point always starts on the existing ground rather the new levels from the first new widening lane.

I 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.

Having issue with the intersection tool for a road widening with turn lane with new roadway intersection. Not repaving entire existing roadway, sawcutting 2' into lane then paving new turn lane. Do most people use intersection tool for road widening, or is it strictly used for new roadways.

I'm working on a windfarm access road (5m wide with widening at bends to 8m) and I need to identify the areas of widening.
I've got the centreline alignment and created the 2.5m offsets to each side. I have also created widening on the insides of the bends using the widening tools and used a linear taper at entry and exit. I now need to hatch up the portions where the road has been widened to demonstrate compliance with the specification and the only easy way I can see is to export to autocad and use the hatch tools (not tried to hatch between alignments).
Whilst this works it isn't dynamic so if the alignment is adjusted the widening alignments are also moved but the hatching remains.

I have created a surface from a corridor. I set the boundary of the surface to the daylight of the corridor. In some areas of the corridor the surface does not triangulate see attached.

Copy a corridor successfully? I'd like to try this just a little worried about the explosion of evil this may cause to my Civil 3D session.
Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.

My corridor surface is not matching my corridor top links. see attachments. this is affecting my volumes!
The section-plan(surface red).png is showing the section editor and the plan view. the red highlighted line in section is the corridor surface and as you can see in plan view the surface is incorrect and wiggly.
The pdf is all my sections with the red linework being the corridor surface.

there has used a non-AASHTO curve widening formula to calculate automatic curve widening for an alignment? I'm trying to use our Agency curve widening formula which is a function of curve radius and central angle.
I'm not sure if it is even possible to use the central angle of the curve for calculating widening, or how one would go about using a non-AASHTO CW formula.
Attached is the curve widening formula that needs to be used. L will be a constant here.

I am building an assembly for a shoulder widening. the sholder is 5' paved plus 5' stabalized tying to existing grade at a 4:1 slope. The two shoulder sections are showing up in the cross section but the tie-down is not. I have checked the target and it is set properly to the existing ground.
See below.

I need to create an assembly where the median width varies , I already created the alignment, profile,corridor,section with the design level. Also I have created the assembly with fix width. Now in the middle of my road the median is getting bigger ,Its possible to link the median with a polyline or another alignment were it change the width ?

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).

We are using iPart - iAssembly workflow with Inv-2013 and Vault Basic 2013
My question is related to released state of iparts. Currently we are generating/ releasing
all the iparts when new member is added in order to manintain the parent child version relationship
Example : say i have a ipart 41020.ipt and i have members 41020- 001 ~ 008 . I check out the parent
from Vault and add 009 member to it.
Question :
Do I have to generate all and check those in to maintain the version relationship between the child and parent inside
Vault 2013 ?
Or
Only generating 009 will maintain version relationship inside Vault 2013

I am trying to generate my quantities by creating sections with template to do the cut and fill, however after i create the corridor and the corridor surface which should use the bottom of the curb, instead it is using the top of the curb. How can i change it so that it uses the bottom of the curb. It is a road crossection which i used from toolpalette, CIVIL3D 2012

I work in Rail Development and I am trying to create an assembly that will automatically generate a rail/tie shape and label Top of Rail Elevations, Track name and number, and offset distance. I have been copying/pasting a block onto each track in every cross section. This takes way too long! I have attached an image of what I want the assembly to look like in the cross section.
Before now, I have been typing in all of that information, when there are 9 tracks and 77 cross sections.

I am creating exhibit drawings and legal descriptions for right-of-way and easement acquisitions. I'm using parcels to create the various objects for the exhibit drawings: parcels allow me to label the acquisition, area, and lines and curves. The parcel property gives me a 'mapcheck' description that I use to generate my legal description. All good.
How are people generating this sort of information for polylines? I will have polylines from my POB to my TPOB that I need to describe. I have artificially closed these polylines to create parcels from them so I can glean the information that I need, but that feels like a work-around.

If they have addressed the issue of being able to generate feature lines as a continuous linetype, like when you turn on linetype generation in a polyline? I can't find it anywhere and I would have thought this should have been addressed by now! Real basic need for plan creation!

C3D 2014
when I created a Top surface, C3D showed me otherwise. I need a gap at an intersection. In the attached DWG the intersection corridor has been removed from view by isolate.
I used 2 seperate baselines to force the road corridor to have a gap at the intersection.
Looked OK .. except ..later .. when I created a Top surface, only the first baseline is used to create the surface, the second baseline is skipped : (
I obviously did not make a gap correctly. What is the correct way? Or.. is there no way .. must the designer create multiple seperate corridors when the road has gaps?

Im using Civil 3d 2012 and I couldn't find the function that I could offset the smooth curve alignment as shown on the attached pdf. I've looked through the offset alignments but those linear, curve-cube-reverse curve, curve-line curve doesn't work much.
