I'm trying to model a corridor with medians and resulting turn lanes (widening an existing street to full arterial). Any good way to model? I have been playing around with having target alignments for the edge of medians, edge of asphalt....but have not been getting the best results.
View 4 RepliesI'm facing problem in designing a intersection. Highway median intersection opposing left turn lanes.
View 4 Replies View RelatedI will be starting to design a 4 lane - 5 lane highway divided by a median. The median will be offset from the cl, stop for the intersection, then continue on the other side of the cl once past the intersection.
I will start digging into the median sub assemblies to try to figure this out.
I remember the old LLD/Civil manuals used to have a description on how to do this. I have 2008 sp2, but only the 2007 manual printed out.
I'm trying to model a tunnel network and I have come across a problem . The problem is best described with an example:
A sort of tunnel - or shaft - has to be blasted in order to make an access between the ground surface and a certain parking cavern. This access will be an escalator and the tunnel will be blasted in a 30 degree angle to the horizontal level. Normally when I design tunnel cross sections (CS) the contractor will blast the designed CS perpendicular to the designed profile.
I drew the tunnel CS with sub assembly composer and created an assembly in civil. I then made an alignment and a profile according to our design. And here is the actual dilemma: Civil draws the assemblies so that the assemblies are vertical and what I need is them to be drawn / modeled perpendicular to the designed profile. Is there a way to do this?
I will attach a .pdf and a .dwg of a surface profile along the alignment created (and tidied up) with civil 3d, in which I have tried to illustrate the problem in case my description isn't clear enough!
I am "trying" to design a intersection that contains four lane divided road. Northbound and Southbound lanes are 2% normal crown with a curbed median. I have alignments for each crown. The intersecting road is not crowned. This road is a retrofit so I am limited quite a bit so the intersection wizard is out. We're going old school with this one.

View 9 Replies View RelatedI am having trouble getting my assembly to work in my corridor. I have a Basic Lane Transition subassembly with a Link Slope to Surface subassembly attached to it. The assembly follows my centerline alignment and the lane widens as designed out to my offset alignments. The slope grading to daylight works fine until the transitional lane starts to widen, then the slope assembly stays at the same point on the lane and does not stay linked to the end of the lane.
I am also having trouble getting the subassemblies to attach to the proper points. I keep trying different OSnaps unitl one seems to work, but I am never sure the subassemblies are connected properly.
What's the best way to model an alley with a 90 degree angle (turn). Do I treat it as an intersection with a zero radius? My typ section is 15 feet width with a 4% slope down to the center of pavement. "V" bottom. Not sure how to get it to model the outside corner and also eliminate the inside overlay.

View 4 Replies View RelatedI have a proposed road with a varying curb line. There is a minimum 5 foot tree lawn between the back of curb and sidewalk. I have used a lane transition and attached it to an alignment to get the curb to follow. Also used the urban sidewalk with buffer widths.
How do I connect the back of curb to the sidewalk and keep the sidewalk in the same offset from the baseline. In the attachment, I have used a zero inside boulevard width and slide the sidewalk over from the curb line in my assembly. Will this work?
what is the benefit of using corridors rather than simply using all of the things that go into a corridor--alignments, surfaces, profiles, sections, assemblies (which I don't understand yet either)--independently?
Is it just for design visualization? Does it have any benefit for developing construction plans?
refer to some bolgs about that how we do this type of transition or accelarationlan lane / deccelaration lane?
View 1 Replies View RelatedI'm designing a single 2% cross flow blke path. I wanted to reverse the cross flow so I created two corridors, one flowing to the left and one flowing to the right along the same tangent centerline. I want to add a 50 foot warp transition in between them. I'n not sure how to do that. I thought of the intersection design but that won't work.
View 9 Replies View RelatedI have a decent understanding of how corridors work, and I am able to generate material volume tables for earthworks, I can edit my corridor and everything is all synced up as far as I can tell. Where I am having trouble is removing topsoil (with a volume generated) and then using that new 'section' to calculate cut and fill.
The project is a new road for a subdivision. Topsoil is to be stripped only within the limits of the back of curb, and anywhere the fill is greater than 300mm (a foot).
What I was trying was to use the stripping topsoil subassembly, with a foreslope of 0:1 and a width based on my corridor. I would have this subassembly on the let and right, and the attachment point would be the crown of the road. Then I would create a surface using the stripping feature lines and the stripping link to calculate the topsoil removed. Then I would use this surface as the Base to compare for my Earthworks.
The problem I was having is the Topsoil surface wouldn't follow the actual topsoil feature line in the sections, and would get some pretty wonky stuff happening with regards to the TIN lines of this surface. Flipping the TIN lines seems very difficult to do properly and efficiently.
What is the advantage of creating a seperate corridor for an intersection? Doing so requires leaving gaps in the road corridors at the intersections which creates a mess in the surface triangulation through the gap. I know we can clean it up by creating a composite surface and pasting all the pieces together but how tediious that is!
I was wanting to keep the intersections as seperate corridors because if we add them to the road corridor we end up with numerous duplicate baselines which makes editing and data management a nightmare.This whole process is a huge time consumer. I can't understand how Autodesk expects DOT's to adopt this software with this workflow.
I am trying to convert my corridors to solids and under toolspace-settings-corridor-commands there is a command called export corridor to solid but this option is not coming up in my toolspace.

I was happy to get my Data Shortcuts set up (1) for myself: to create corridors of different design scenarios in separate drawings, and (2) to share data with my project team members.
Referencing and viewing them seems to be ok.
But I haven't been able to model a Corridor along an alignment, profile, tying to surface referenced from data shortcuts. I think I did once, then had problems after removing and re-creating, maybe re-naming some Data Shortcuts. Is that a "No, no" ? I didn't mess with any of the XML files, created everything from Civil 3D. I might have to delete everything and start with a fresh Data Shortcuts folder.
When I re-select Alignment and Profile for Corridor, then OK - it locks up. I created new sample lines along the new alignment. Maybe need to start with fresh corridor. How much am I going to have to re-create? Possible hang up locations?
Trying to add slope markings on my corridors, and the only way I can find is to do it in the Corridor properties > Slope markings, then click add slope pattern, which asks you to select featurelines top and bottom of slope. Surely there is a way to simply switch on or off slope markings where in cut or fill?

View 1 Replies View RelatedI've changed my workflow slightly and have created 4 junctions via the wizard but kept them all in the same Corridor (previously I kept each one in its own corridor).
I now need to create the formation surfaces for the corridor (in the way I always have done it) but only one of the junctions has a surface. I then added a show boundary and the "missing" surfaces appeared but with many connecting triangles and superfluous triangles in the curved areas.
How to get a nicely shrink wrapped surface or is it a matter of brute force removal of triangles etc?
I've created a T intersection and have created the surface for the T corridor and the entering side road. The surfaces appear correct. When I create a surface for the main road, which has been split into two regions, the surface goes thru the T corridor. How do I create a surface that simply goes up to the T intersection and picks up again after the T intersection?
View 5 Replies View RelatedI have a mainline corridor which is intersecting with a side road corridor that is curving towards the mainline. After the PT of the curve, the two alignments are parallel and I am using an offset assembly here for the sections. What is the best way to handle the area where the two corridors are coming together. As far as I've been able to tell, I cannot use an offset assembly through the curve. There will be a ditch between the two that needs to be shown someway or another. I've attached a screen shot.

i make grading to surface, and make corridors,,,how to combine two segment?
I'm thinking of creating separate corridors for my stripping calculations and then using the stripping datum surface as my main EG surface for a more accurate Cut/Fill quantity. In this instance I have 10 corridors for my primary roads, and adding another 10 corridors for the stripping seems like a lot of effort, but it's probably necessary.
View 8 Replies View RelatedI am new to Civil 3d, and have just completed the first pass on a design that includes several corridors. I am confused on the best way to prepare actual drawings.
I initially thought that plan production would be useful, however it seems that these are fixed. It seems odd that draft drawings cannot be present for review and editing. Is this correct or am I missing something?
It also seems like a huge task to generate the styles required to present the corridor in an appropriate format for a drawing, let alone several drawings that may have different requirements - in particular for a new comer who would not have set up the range of styles.
Therefore I consider two approaches are feasable - XREF the corridor or Extract Polylines.
I now think the best way to prepare drawings is to export polylines of the key components of the corridor and prepare drawings using this. This would be combined with the alignment, pipe and surface data, that can be used in the drawings via Data Short Cuts.
Is there a way to toggle visibility of a corridor in a drawing where the model has been Xref'd into? The problem I am having is that we have one Model drawing that has a corridor.This Model is xref'd into multiple drawings. Not all drawings should show the corridor.
The only way I have found so far is to go into model and toggle the corridor on and off depending on which drawing I want to print or view. It creates problems when you want to run a Publish of multiple drawings because you always have to goof with the Model file. This seems a bit of a step back from being able to toggle visibility of objects in a drawing file with an xref atached and leaving it that way and ready to be printed at any time.
In terms of data passes from one subassembly to another, is the connection point data x,y,z
the only information that is passed on from one subassembly to the next , or is there a way
to access other properties of the adjacent connected subassembly.
What I am attempting to do is to create a subassembly in SAC to get the slope and length of the connected subassembly above.
I have a main road corridor and a small access road corridor that intersects the main road. I don't want the intersection to have curb returns because I just want the access road to act as a driveway enterance (main road curb will run straight through and just get depressed at the access road enterance). However, I want the daylighting for the main corridor and the access road corridor to match up at this intersection and I'm not sure how to do this.

I don't want [All Codes] to be used, and since I created a style for the project I'd want to be able to use it when creating corrridor using the tool.
Toolspace Settings seem not to have relevant option.
