AutoCAD Civil 3D :: Intersection Circular Dependency Errors
Dec 20, 2012
We have recently made the switch to Civil 3D for our firm and are running into some issues with intersections. I am getting an error stating that "The primary road for this T-junction will result in a circular dependency with the existing intersections." When trying to make an intersection at the middle intersecting road of the northern road going across the top of the screen in the attached image. The norhtern road is defined as secondary at both endpoints and the intersecting road is defined as primary at the previous intersection. At this intersection the northern road will need to be primary and the intersecting road secondary. I would prefer not to break up my alignments as you lose some of the dynamic nature by doing that and vertical curves can become an issue.
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).
What distinction is between “intersection” and “apparent intersection” in snaps,. I’m not sure what difference is between the “intersection” and “apparent intersection” in snaps.
I have a problem fo cycling dependency when I try to do a notch in a particular case.
I have this frame sample. I need to notch each frame parts. I realize 3 notchs, first one between 1 and 2, second one between 3 and 4. This two notch are realized without any problem.
When I try to do the last notch between 5 and 6 I have a cycling dependency error message. I don't understand why and how to solve the problem.
I have been getting this error message alot with 2013. I never got this before with previous versions. I do alot of assemblies that are made of parts that are derived from a main sketch part. The only way to remove the error is by deleting the right part out of the assembly and I can procede. I have read that it has something to do with renaming parts, but I still dont completely understand how I am getting this error. My work flow is the same.

Just upgraded to 2013 about a week ago. Random part files seem to be giving me the same error message "A cyclical constraint dependency has been detected." Some of these parts are ones that worked fine in 2012 and some are ones that I created in 2013 and worked fine for a while, but then started giving me the error later on.
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.
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
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.
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 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.

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?
I wonder how to get intersection lines between two surfaces in Civil3D API. It seems that the "MinimumDistBetweenSurfaces" command in Civil3D can do this work. But I can't find corresponding API.
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.
I believe that I need to define a custom Expression and then add it to the Label Style of a Tangent Intersection.
1) I'd like to add the max superelevation (e max) value of a curve to the label. This might be impossible. 2) I'd also like to add the design speed value to the label as well. This could be pulled from that value set in the design criteria of the alignment creation.
