AutoCAD Civil 3D :: Match Daylighting Between Intersecting Corridors?
Jun 18, 2013
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'm trying to successfully get through a corridor, but to no avail. I'm certain I'm missing a step, and I'm certain that the step I'm missing is setting a surface to daylight to.
My project: It's a simple grassed waterway in a parabolic shape that is ran on a proposed profile grade up a draw. As you can see in the screen shots, it should daylight to the surface on each side. You can also see that the majority of the profile is deeper than the assembly is tall, so I should have a corridor that daylights on each side with a gradual cut up to the surface.
I profiled the centerline with offsets. I need the offsets to see how deep to lay the proposed centerline in regards to how deep my waterway will be. I get a bunch of error messages when I run the coridor, and they all deal with the offsets.

Am struggling to pull off some corridor but the standard daylight subassembly is letting me down. It mulfunctions when I connect it to the Generic Linktoslope subassembly. In some Areas it works fine but in others it doesn't. My plan is to apply a ditch at the point where the LinktoSlope meets the ground level and to have this ditch again daylight back to the target surface.

This is my first corridor and I've been slowly working my way through it, but just seem to be running into problems left and right. My latest problem is the following;
I have my Corridor's Subassembly Daylighting set to target my Left side 33' R/W offset alignment. For 90% of my alignment everything is working fine or at least appears to, but I have 3 different areas where the Corridor refuses to daylight from the bottom of the 1' ditch out to said left alignment target even though the ditch is well below existing grade. I've attached 2 screen grabs.

I 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?

How do I project the Proposed Road Level information from Road_1 at the intersection of Road_2 (Alignment_GA.jpg) onto the Start of the Profile for Road_2 (Alignment_Profile.jpg) to give me my tie in start point?
How do I obtain the exact change of the intersection Point? How can i extend Road_2 onto the horizontal curve of Road_1 so i know they exactly intersect?

I'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.

I 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 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?

How do you merge a ramp on to the main highway using corridors? Also how would you make that surface with two different alignments? I have my main road alignment and a ramp that comes on to it so the problem I'm having is making my 3d model with the road and surface combine.

I have two corridors and when I look at the sections I only see daylights of one corridor.. I set all targets in both corridors.

I'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?

I 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'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.

I 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.

Lets say you have a polyline snapped perpendicular to an acr and you start zooming in they tend to separate. In the past a simple regen would magically make them display as intersecting lines (no gap or overlap). Right now the regen isn't working and I can't figure out why or what changed. I tried changing the VIEWRES but that didn't seem to work. What else could it be? I don't even have to zoom in that far to notice the overlap.

Is there a way to change the default Style Set that is used by the tool?
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.

Is it possible to change the parameters of a subassembly - for example in an assembly comprising several subassemblies, can I change a parameter in Subassembly.LaneOutsideSuper, for example, to vary the Lane Width from 4m at CH90 to 3.25m at CH160m and keep it at 3.25m for the rest of the corridor.
I am new to Civil3D.

I'm modeling a hydro scheme access track about 4m wide that meanders down a steep hillside at 1:8 with a couple of hairpin bends where the gradient is 1:20, what is the best way to model this?I have got polylines to define the hairpin and also offset alignments but I need to ensure that the outside edge of the hairpin at entry is used as a level target for the inside edge on exit for the length of the hairpin.

I've created a few subassemblies with the SAC and I'm having problems with creating corridors.
When I import the subassemblies they always show up named "Subassembly2". Is this due to some installation problem... it wouldn't be a problem but I will be importing a lot of subassemblies and wouldn't mind cutting down my workload...
Another problem is that when I try to reimport an edited subassembly it will not update in ACC3D2010. I read somewhere that one has to restart civil in order for the changes to take place and that DOES work but is there perhaps another, more functional way, of updating subassemblies?
My third question is about corridors. When i try to make corridors with previously mentioned assemblies all goes well, untill (pause for dramatic effect!)... I add regions to the corridor. What happens is that the corridor doesn't model the different assemblies and only uses the assembly I first assigned to the corridor when creating the corridor.
What I'm trying to design is a set of tunnels where the tunnel cross sections and the elevation of the bottom changes.

I've recently started working with Civil2012/2013 (bit the bullet you might say).
I attended a course on civil about a year ago but it didn't cover all the bases.
My question: stripping calculation, is there a way fro civil to perform it automatically?
One way to calculate stripping (manually) is after i have all the tin volume surfaces, is to show the fill areas in the volume tables and then do the calculation myself.

I am preparing to model a road surface for a waterline project. I would like to be able to generate sections at desired stations showing the sewer, storm drains and joint utility trench along with the proposed water line. My plan is to model the road surface using a surface created from gradings and then create the pipe networks and joint trench.
My question is whether gradings or corridors would be the way to proceed. I have preliminary design data on the road surface which is sure to change.
