AutoCAD Civil 3D :: How To Model Two Parallel Roads With A Median In Between
Aug 23, 2012
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?
*Edit:
I am not sure if i would be able to do it with only one baseline, as the roads may not always be parallel.

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 .

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
IF NOT--
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.

It can be done using the LaneFromTaperedMedian subassembly, and that there is a webcast explaining it. I have checked with Autodesk, and the webcast is no longer available. Any detailed instructions as to how to accomplish this. I'll attach an image of my median.

I have a baseline profile as a finished grade of a roadway corridor and want to add raised medians within a portion of the corridor. best way to have the medians adjust as the profile grade changes?

C3D2012..I have an assembly with left and right curb subassemblies, they are spaced about 1 m apart. I want to connect the BOC's with a constant slope median. I bring in the median and connect it to the Left BOC and it attaches, but shoots the median for 20 m across the assembly to the right. I tried to put a marked point on the right BOC prior to bringing in the median assembly, but the same thing happens. I changed the marked point name to RTC (Right Top Curb) and also changed the name to match in the median subassembly, with the same results.
Any proper way to insert the median and get it to connect properly.

My part is at an arbitrary angle relative to one of the planes and i cannot align the view in a drawing to be horizontal.I try to make a view, in the part file, in which the model will be horizontal, but there isn't any precise input for views.
I used the Look At tool to look at one face and all i need now is to rotate the view 90 degrees round one axis, but when i touch the line of the compass in the Constrained Orbit command the view jumps back to some position.

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 ?

I have problem with medians ( Both MedianRaisedWithCrown and MedianRaisedConstantSlope) when crossing center line ( i.e whole median has to cross the center line).
I have median that goes along the centerline and it has to move to left completely ( whole median is on left side of the centerline) to cater for left turn. I tried with MedianRaisedWithCrown and MedianRaisedConstantSlope but it did not workout for me.
I used alignment ( for cl ) and offset alignments for median edge and etw. I have problem when the median edge ( offset alignment ) cross the center line and continues. I can see etw and median feature line shifts.

Here's my assembly :
and
when I tried to assign the Median Width in my corridor to a polyline representing media width,
I got this overlap in my Section view :
how can I maintain Objects in this cause "Lanes" attached to median no matter width change ?

I 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 have two alignments that are not parallel that make up one corridor. Each alignment has a separate profile running along it. At stations where I have a template drop in my section editor, it is not representing what is really happening because it just is perpendicular to one alignment. Is there a way to develop a secondary alignment that will have my section editor show what will be parallel to both alignments.

As you see in the picture I have a subdivision that follows a curving road, and therefore all the lot lines also follow the road. This is unfortunate, as I have been creating label styles 1 by 1 for left, center, right, for every angle of line. Is there a way to get your label to go parallel with the line automatically?
What I am thinking of is with structures, there is that circular grip that rotates the structure, is there something similar to this with labels? or must i keep grinding away making the labels one by one in their separate degree intervals.
Right now I have 33 label styles.... and I am not even 1/4 of the way done.

How do I merge 2 corridor surfaces that are running parallel to each other. Due to this being an overlay project the CL will stay the same just raised 4.5" from existing CL and the existing cross slope varies which we are matching until you hit the sawcut. We are not ripping out or milling any apshalt, it is strictly an overlay of the exisitng with 4.5" of new asphalt. We are saw cutting 2' either side of theedge of paveement and matching in with proposed.
I have created a feature line over the existing cl then raised it the required height. the cl has been offset 10 both sides to create my left and right shoulder alignments, I then created a left and right shoulder corridor assembly which has supplied 2 seperate surfaces. I now would like to merge the 2 surfaces using the raised cl feature line as a break line to create the final proposed surface. I would prefer not to have to create feature lines from my corridor and create a new surface because i would like to take asphalt and subgrade quantaties at the end with out having to hand calc but will if need be.

I have a water and sewer line that run parallel for the most part. The sewer starts at 10+00 runs west and then turns north about 10+80 and parallels the waterline from that point on.
I want to show the sewer in the water profile as beyond and to reference the sheets to see for P&P information. This works fine.
When i go to show the waterline in the sewer profile it does not show up correctly it only shows up in the initial 80 feet of the sewer profile. Is this because the two alignments are not parallel with each other until that 2nd manhole?
See attached profile PDF.

I am trying to create a best fit alignment from parallel linear sets of COGO points. When I run the command, about halfway through the data set the alignment suddenly curves out of away from the COGO points. I tried doing a best fit individually on each side, one side works fine, the other sets station zero about a quarter of the way into the points and runs it back toward the start, leaving out 3/4 of the points.

I have two feature lines. They are not parallel.
The tool "Adjacent elevations by reference" seems to work fine only when feature lines are well parallel one to another ?
Also, it seems that C3D method works fine if "parent" object and "object to edit " have similar number of vertex, similiar "lenght",....

My colleague added parallel pipe networks and crossings to multiple SD profile views yesterday. Today, he came in, turned on AutoCAD, opened the drawing, and the parallel pipes and crossings were gone. The working folder had reset itself to nowhere so we reset the working folder and Data Shortcuts Folder, but that didn't bring them back. We can go into the profile view properties<pipe networks tab and turn the pipes and structures back on and override the styles, but that is basically redoing everything we did yesterday. Is there a way to avoid having to redo everything? Is there a way to avoid this from happening in the first place?

I am currently using AutoCAD Civil 3D 2010 for surveying work and have been trying to figure out how to use part of an existing survey of land model. I have it in a layout (paper space) and used a viewport to get the section I am after but there are some changes in labeling and minor model modifications needed to make it a stand alone model and I do not want to modify the original model to make these changes. How can I take a section like I have in view port and make it into its own model with a different scale so the changes can be made and the original model is left in tact?

I'm designing a map in Illustrator CS5. Any way to merge 2 paths (roads) which have text attached, so they seamlessly blend together. I've tried using a compound path but this doesn't work with text added. I need to be able to easily change the roads direction/shape without having to use different layers.

CIvil 3D 2013 / My drawing opens in layout view and all model objects are appropriately coloured by layer. If I hit plot at this point, my colour dependent .ctb file works fine. However, once I swtich to model view, all my linework turns white and if I switch back to Layout view it remains white and plots each line with the weight assigned to the colour white.

I am trying to work on a previous file in my office, and when it opens on mycomputer, it does not display as it should.
In general, the purpose of the project is to reinstate the side slopes of a road abutting a river. Cut & fill sections have been generated on 20m station increments along the road corridor/surfaces in order to calulate cut and fill as well as to reference the design to flood levels.
When I open the file, all of these sections (and there are alot) have relocated themselves to various locations in model space, none of which are aligned with the viewports that are being used for printing.
Could it be software and/or hardware incompatibility with the computer they were originally created on? (I believe it was created with C3D 2010, or C3D 2011 - I am currently running 2012)

I am trying to collect the mean, median, and mode of the RGB color values for a lot of different images.. Instead of just exporting the histogram raw data, I would rather just export what you see in the 'statistics' window when you open the histogram window.
Also, if I just wanted to transcribe it myself, I am not even able to keep the histogram window open while typing the data in excel.. So I constantly have to click back and forth (or just get better memory)..
