AutoCAD Civil 3D :: Best Fit Alignment From Parallel Linear Sets
Sep 21, 2012
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.

Is it possible to modify a label set to a new starting station, e.g., instead of the alignment starting at 0, change it to start at 100?

Basically, I have two workplanes which are parallel to each other and offset by a certain distance. As illustrated in the picture below, I'd like to constrain points from each plane to have the same vertical alignment as those from the other plane (horizontal too, I suppose, but the horizontal dimension will be the same anyways).

i've made a serpantine curve that starts from one line of alignment and end on the other line.
i wanted to know how can c change alignment direction when these two feature line and alignment meet each other in order to change the alignment path?

I using a data reference/shortcut to properly label an alignment in paperspace. However when I reference the alignment in and apply the labels the aren't the same as the original alignment that I am referencing. Is there a setting where I am supposed to apply a new beginning station.
Also it seems as though the stationing(distance) isn't even matching up 1:1 with the original drawing. For example in the original base drawing my alignment starts at 10+00 with the next PI at 14+76.98, but the stationing on the reference alignment starts at 0+83.33 with the very same PI being labeled as 1+23.08. So the very same distance is 476.98' in the real design and the drawing it's being referenced in, but the stationing of the referenced alignment shows it as 39.75 Units.
I've attached a screen of the beginning of the alignment.

Using Civil 3d2012, Is it possible to change the alignment label style set after the alignment has been created? For example, for an alignment that was created with alignment label set X - change the label set to alignment label set Y? It seems like this should be pretty easy, I must be missing something obvious.

I have a question on Alignment PI's. (Point of Inflection/Intersection)I have an alignment where some PI's have curves, others are merely hard bends.
Is there a way to automatically label the PI's even if they have an associated curve? (I'd like PI, PC and PT)Alternatively, can I only show markers at PI's without curves?

I'm trying to edit some existing alignments. When I create new entities, they do not show up in the alignment grid view. Why is this?

Launching alignment grid view/alignment entities,
I’m wondering if there is a way to launch alignment grid view/alignment entities (attached) without the need to first launching “alignment”? This dialogue box is quite essential in editing the values of radius, degree of curvature and deflection angle for the selected curve.

Can I inherit the station from one alignment as the begin station for another alignment?
For example. Alignment 1 is 1000 ft long and starts at sta 0+00.
At sta 8+01, Alignment 2 begins and goes off in another direction.
I manually enter 8+01 for begin station Alignment 2. Life is good. Still in the design stage, and customer needs to modify Alignment 1 to avoid something. Now Alignment 2 intersects Alignment 1 at sta 8+15, but same N/E coordinates.
I manually enter 8+15 for begin station Alignment 2.
It would be better if Alignment 2 could inherit the begin station based on the new stationing from Alignment 1.

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 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 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?

way to renumber an entire sheet set without having to stop at each subset? Currently, I right click on a sheet and select "rename & renumber". The Rename and Renumber dialog box pops up and I type "1" then click on "next", type "2", "next", and so on. This continues until the end of the subset, the stops. Then I have to right click on a sheet in the next subset and start over.
I want to renumber the whole plan set without stopping at each subset. Obviously, I can get rid of the subsets, but that isn't my question. I want to keep the subsets and have the ability to renumber the whole set.

I have made a model with 40 viewframes. I have used the option to export 4 layouts to one drawing. My question is can I revise the original model and get the revisions automatically updated in the 10 drawings or do I have to redo the export option?

When I create my sheet sets, where there is a curve in my alignment, there is a black space outside of the matchline. When I move the matchline closer to the end of the view frame, the black space gets smaller. Then I cannot acheive my overlap.

What do you use to Print your large Sheetsets ? Do you use the Publish function within AutoCad ?
Do you use Acroplot or any other 3rd party software ?
I had to print around 80-100 Plan and Profiles Sheets, Sections, Coverpage, Index, Legend, etc.

I want to set my autosave (In Options) at 30 minutes but it seems that my Civil 3d 2012 sets itself back at 10 minutes.
I even try to set it in the dialog box with SAVETIME command at 30 minutes but it gives me the a prompt telling that its been setted at 10 minutes.

i have a bunch of pipes we surveyed in the field, the linework code we were using was p01 B 10"
the "B" being "begin"
my description key set is set up as follows:
p## = Code
and
Ex Pipe $1= format
the trouble is, this works nicely for all of the inbetween shots, but for shots containing "B" and "E" it uses the B for the $1 instead of the desired 10" pipe size. How do I prevent this from happening?
We were origially using the code B p01 10" but the description keys were geting hung up on the B and not sorting the point to the desired layer.
what is the best method for coding in the field? and how do I get the 10" to show up in the label instead of the B and E

I'm trying to figure out where to control the section label sets that are attached to the section "entities" when I create multiple section views. It seems to default to 'standard' for all entities sampled. I have created the section label sets that I would like to use for each entity, eg. subgrade, finished grade etc., but don't know where to select it when sections are created. I can get desired results by selecting each entity in a section view individually, but it's very tedious since I will have over a hundred sections views to show with 3 entities sampled each. These sections were created from sample lines across multiple surfaces and not from a corridor. It seems logical that the section label set would be tied to the section style, but I don't think it is. The only thing the section style seems to control is the layer and a name, it's nearly useless.

I'm having an intermittent issue with my publish command. So far the pattern seems to be on drawings with a larger number of sheets (last one was 15, this one is 7). When I get the publish dialog box, I'll set the number of copies to however many I need but it ends up only printing one set. It doesn't happen every time. Just with these two drawings so far. They have nothing to do with each other and haven't shared any data. The only similiarity is that they're both older projects that were started some years ago on previous CAD versions.

I was wondering if it was possible to restore a rule set to an existing pipe. we created a pipe network with about 100 pipes in it with a min. depth set to 6 ft. the pipes all came in with varying slopes, which is what we intended. someone in our group went through and set all the pipe slopes to zero for some reason and we need to undo that. this was done on the same day the drawing was created, the changes were saved and the drawing was closed so we can't "undo" and there is no previous version to restore to. my question is, is there some way we can select the network and "restore" the origially intended rules, or are we stuck with either redrawing all the pipes or manually changing the slopes back. (both would be an extreme waste of time)

Any way to stop the recently opened Sheets Sets from showing up? To me, it's highly irritating and they always crowd out my .dwg's. All you have to do is open any sheet file and the Sheet Set Manager opens automatically.

I want delete all breakline sets of one selected surface using API.
There is "SurfaceOperationAddBreakline" but I don´t find "SurfaceOperationDeleteSetBreakline" for example.
Is there other way to delete all breakline sets of one surface?
Later, I want to create one set breakline for each layer which has been selected by user.
I know that I can use qselect, but I want do this process automatically.

I imported Google earth surface (at eye alt 600m) to civil 3d 2012 and created an alignment of length 181m.
When I exported same alignment to Google earth , it showed the length as 190m ( the difference increases with increase in length of alignment) And also the profile view of the alignment in the Civil D & Google earth varies.
