AutoCAD Civil 3D :: Create Intersection Between Two Roads
Dec 10, 2012
I m trying to create an intersection between two roads. See the attached jpeg. When i open the corridor properties i receive an error message which i don't understand. It seems like civil 3d has problem with the order of the regions. Also the corridor sections intersects in the area that i have place a remark "problem". I m trying to correct it manual but when i rebuilt intersection then it overlaps my manual correction
Creating an intersection of two roads. I have created corridor using alignments, profiles and assemblies. then i have created the intersection. However, i find it quite strange. Maybe it's because of the assemblies. . I am attaching the file herewith .
I am trying to create an intersection design using the Intersection Tools in C3D 2012. I followed the steps in the tutorials, created a corridor on the major road, splitted the regions, created the intersection and added it to the major road corridor, and connect the regions with the intersection portion.
I used the same assembly throughout the design just for simplicity, however, i notice that there are gaps of curb between the curb return section and the through section (as outline in red rectangles).
The street is a 'T'. The alignment is extended... Sta 0+00 starts 100' back and the intersection at centerlines starts at 1+00. The alignment is masked between 0+00 and 1+00, but that obviously doesn't make a difference for the intersection wizard.
The intersection wizard does not give me a choice, it just presumes a 4-way intersection. How do a do/choose a 3-way 'T' intersection in this case?
Is there a particular reason that the intersection wizard will not create the profiles if you select the horizontal alignments rather than let it create them by offset?? My EOP is not always parallel to the centerline. Why bother giving the option to pick out a name if it isn't going to work.
i have a question for the gurus. how do i accomplish modeling two parallel roads with a median in between? in other words, say a northbound (NB) and a parallel southbound (SB) roadway, with a grass median in between them. the both roads have crown, and then eventually slope down towards the median, and at one point they meet.
I am curious to know if say for NB and SB, i have an assembly with the lanes, then shoulder, and then median area past the shoulder at x%, what subassembly should i use to accurately model the point where the NB and SB x%s meet?
I am not sure if i would be able to do it with only one baseline, as the roads may not always be parallel.
Is there a way for the program to automatically change profile elevations of intersecting roads.
Say for example i have two intersecting roads ROAD A and ROAD B.
On my ROAD A profile at station 0+300 i have a proposed road elevation of 9.5 On my ROAD B profile at station 0+000 (intersecting point) I have the same proposed road elevation of 9.5.
Now i change my ROAD A profile at station 0+300 to 10.3
Is there anyway to allow the program to automatically change my ROAD B profile elevations to 10.3
and I have to use the Annotate > Add Labels > Profile View > .......................... labels,
Is there a way for those labels to link across the profiles such that , On my ROAD A profile at station 0+300 i put the label at the elevation of 9.5
On my ROAD B profile at station 0+000 (intersecting point) I have the same label at the elevation of 9.5
Now i change my ROAD A profile at station 0+300 to elevation of 10.3 then is there a way for it to automatically raise the ROAD B elevation label
So that I would know, without having to manually check through, that there is a discrepancy between those intersecting roads. So the real list of my query is whether I can link my alignments, profiles or annotation labels.
I have feature line with elevations that represents bottom of ditch and want to go UP 3:1 slope. also i have edge of road feature line that is higher than ditch and want to go 2% down until it hits side of the ditch that is 3:1. Any easiest way in civil 3d to create intersection line between ditch bottom going up 3:1 and edge of road going down 2%?
What is the best way to relocate and intersection (created with the wizard) from 43+00 to 40+50? I dragged the alignment but the return baselines don't seem to come along for the ride. Would it be better to bite the bullet and redo it?
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.
I need a style for intersection of alignments that automatically includes the abbreviations for Point On Tangent (POT), Point On Curve (POC), etc. I can create a style with the basic information of Station, Alignment Name, but adding the POT, POST, etc. in front of all alignment’s stationing and name doesn't seem available still in Civil 3D 2011.
issue with my Corridor. It involves the intersection of a main road alignment and a secondary road. Thing is my main road has a 6' shoulder whereas my secondary road doesn't have a shoulder at all. I used the Intersection Wizard to create the Intersection, but the two templates don't align. Without the shoulder the ditches don't line up. I tried drawing a polyline between the two ditches and targeting it and that worked, but then realized that going from 6' shoulder to no shoulder wasn't working either so when I tried to target a polyline from the 6' shoulder to the edge of pavement all kind of stuff happened that didn't make sense to me.

I have a site access road that extends from highway into site and then loops around and intersects with itself. Would like to keep this as one alignment in order to make Super Elev and master alignment easy to control across project team.
Issue is, we would like to use Intersection wizard at the intersection but cannot, as we ony have one alignment. We could model the intersection the old way, using kerb returns with design profiles, but as the design is still in early stages the intersection is likely to be frequently revised.
how we could utilise intersection wizard in this scenario?
I have a problem modeling intersection. This is first time I am modeling intersection. I have gone thru' and actually did all intersection tutorials offered by C3D and naturally I felt like I am ready for it.
But in real world I am not. I am trying to model intersection and I keep getting error as "Value on Wrong side of alignment to profile". I looked at target mapping and thinks so that all is okay (may be not). I am attaching snapshot of error message as well as plan view. I wanted to forward actual dwg but size is too large to post.
Point to note:This is Left lane driving setting. I realized this after I created alignment/profile/assemblies but before I tried intersection modeling.
I would like to know how it would be possible to manipulate the Intersection Wizard so that I can obtain the required shape as drawn by the architect. In essence create a "round about" shape. see the attached image for furhter detail.
My corridor surface randomly bounces from top links to bottom links through the intersections even though I specified top links only and my corridor is modelling correctly.
Previously I just deleted the surface and recreated it with no errors but it doesn't seem to work now. This happens with both manually created intersections and ones created with the intersection tool.
I have a super-e road assembly as shown that is running into the intersection of a future road stub. I can not figure out how to get the sidewalk to grade out in the intersection transition I have created for the curb return. Any way to get through this situation?
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.
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 have created a label in Settings>Intersection>Label Styles>Intersection Location Labels. The label will annotate the intersection stations and alignment name - however I haven't been able to configure the northing, easting and point number of the intersection.
