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 that will give me the volume of a new shoulder along an existing road, as show in this picture.
I can easily make an alignment along my edge of pavement, and match the existing elevations, but I need to hold the cross slope constant AND the shoulder slope constant, and have the bottom of the shoulder slope to a target 2 feet off of my ROW.
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.
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 ?
View 4 Replies View RelatedI'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 attempting to use the Superelevation tool on an interchange. I have 4, 1-lane ramps that I need to apply superelevation to. The three issues I have (so far) are:
In the Calculate Superelvation Wizard...
1. In Roadway Type, I don't know what to choose, I'm leading toward Undivided Crowned (center Baseline ) because my assembly (as of right now) is set up as an undivided crowned roadway (with the crown on the west travel lane edge). Which Roadway Type I should choose (for a 1-lane Ramp with different shoulder widths?)
2. Moving on to the the Lanes category doesn't matters. I uncheck symmetric Roadway, hoping I can choose "0" for the number of lanes on the Left, or at least put the lane width down to "0" but can't do either. I uncheck the Symmetric Roadway and it still makes everything symmetric (it acts as though it is still checked?) I only want to show a single 15' lane. (I even tried to use undivided planar, and put both lanes at 7.5'each, but then I still have shoulder issues...)
3. Move to the Shoulder Control. Why doesn't it give me the option to do different shoulder widths? On ramps it is very common (at least in Wisconsin) to have an 8ft shoulder on the right and a 4ft shoulder on the left. How can I type in 2 different shoulder widths.
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 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.
View 6 Replies View RelatedI 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'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.

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.

Im using civil 3d UKIE 64bit, having a serious problem with adding a lane widening to an offset alignment. It is a straight alignment approx 200m length, but when i enter the parameters that is asked, at the end it says no solution!
View 2 Replies View RelatedAlthout 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 need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.

I am attempting to x-ref a building model that was drawn in 2013 MEP in a Civil3D drawing that contains the site surface. When I x-ref my building model into the site drawing and attempt to align and scale the building some of my walls become broken and missing. I have a feeling this is a scaling issue because on my site my north wall should be 24' long. The wall is 24' long in MEP, but that same 24' from Civil3D is only a 2' line segment in MEP. How to remedy this? I have tried scale the building model down in MEP first and it causes all kinds of problems with the door and window objects. I tried adjusting the x-ref scale prior to adding the x-ref and it does the same thing.
View 9 Replies View RelatedI thought I created a rail sub assembly.
So I created the rail sub assembly everything looks great in sub assembly composer.
Start a new dwg data reference in the rail alignment, Note the rail alignment type is set to rail.
Create an assembly and under the Construction tab for the assembly the Assembly Type is set to Railway. Attach my custom sub assembly to this assembly.
Created a corridor and I get this error: Something wrong with current subassembly: Operation is not valid due to the current state of the object.
So I delete my sub assembly attach the Civil 3D Rail Single sub assembly. Re run corridor and everything works fine.
So I promote the alignment change type to centerline. Delete the Rail Single sub assembly put my rail sub assembly back. Rerun the corridor and everything works.
So then I undo everything up to the point of promoting the alignment.
Opened the base file changed the alignment type to centerline.
When I tried to synchronize the references I ended up a broken reference with the following error. Invalid reference. Synchronization failed
Not good we already have plan sheets cut.
where in sub assembly composer were do I define the sub assembly to be for Rail?
I've got a tool palette that I use which has about 5 or so tabs with about 10 to 50 standard blocks, tables, etc in each tab that is organized by text headers and dividers. It's such a productivity booster I exported the palette to a place on our server that everyone can import them from. My problem is that when they import the tool palettes, the icon images dont come in. We're left with manually updating all the images which is a problem when certain people "don't like change" and don't want to take the time to deal with the technical problems. Maybe I'm missing something, but shouldnt the images come in when you import the palettes?

I have created a building pad on my site and need to extract fill quantity. I set the elevations on my building and created a 5:1 grading object. to the existing ground.Autodesk Instructions are, for the actual building footprint, that I need to create a grading object at 1:1. for the area covered by the actual concrete pad. Need screen shot of the style settings of this grading criteria. because the area is flat it is impossible to determine if the floor area has been built. When I run sections and create volume reports the only fill quantity is from the grading objects that slope out from the pad. I must be overlooking a setting in the style for 1:1.

View 5 Replies View RelatedIs it possible to use a custom properties within part builder to calculate pipe sizes?
Within part builder I have created a new parametric part under the rectangular pipe chapter.
This new parametric will represent a electrical conduit ductbank that will vary in size depending on the number of conduits in the ductbank. For example a 2 x 3 ductbank would have 2 columns and 3 rows of a 3" conduit. So the width and height of the rectangualr duct bank would be calculated this configuration. I will have up to 12 rows and coluimns in a single ductbank, so I might have a 10x10, 3x12, 12x 1, etc.
I have a custom pipes catalog and within the AeccPartParamCfg.xml I have created 2 custom propertes named ROWS & COLUMNS.
My question is can this custom property be used to calculate the the height & width on the rectangular pipe within part builder? Once I draw my pipe I would like the ability to edit ROWS & COLUMNS within the Pipes Properties to change its size. is this possible? See image below.
When working with multiple building pads and configurations change rapidly. Is there a method to add a Block or Xref into a Civil3D Surface under Drawing Objects? If so, how could you do it.
I want to have a building block type 1 that I can update the block or xref then updates the surface rather than doing each one individually. The Block would have a FFE of 0.00 and then the stoops, etc would either be a 0.1 drop or so.
I have a Proposed Building Pad. Grading is 3:1 on 3 sides. Grading is 5:1 in the front of the building. How do I get Grading to fill in the area at the building corner between the 3:1 and the 5:1 grading? I thought infill would accomplish this but it seems to have no effect when I select the objects. I included a screen shot and the area at the left corner of the building.
