AutoCAD Civil 3D :: Alignment / Surface Not Automatically Synching Upon Open?
Apr 15, 2013
I have a drawing that suddenly stopped synching one of the alignments (the others synch fine) and the two surfaces that are referenced. They are all data referenced but require me to open the drawing and manually synch the entities each time. This drawings was functioning perfectly until this began just recenlty. I've searched the forums but can't find anything. I'm assuming maybe some system variable is wacky but that doesn't explain why the other alignments sync just fine.
I need to place points automatically and in order sequentially along an alignment and I need to generate data from the points relative to an adjacent alignment. SO, two alignments, adjacent but not parrallel to each other. The data would then be point #, sta and offset from the adjacent alignment with the points placed in order and by window or crossing. I have a few thousand to place so one at a time would be an undesireable solution of course.
I am working on roadway project where I am using Pipe Networks to layout the drainage infrastructure. I have set my working dwg up so that I am data referencing the existing surface and proposed alignment. I have set my pipe network up so that it is also referencing this surface and alignment. Everything was working fine. Labels were pulling the correct information from my surface elevations, and stations were being referenced as well, until I got a message that recommended that I recover my drawing.
I ran recover and my surface and alignment data shortcut disappeared. My pipe network now shows questions marks where there were once stationing and it appears that the surface and alignment have completely disassociated themselves from my drawing, however they appear in the prospector, but cannot be refreshed. Again the data shortcut symbol is no longer next to my surface and alignment, but there is a symbol telling me that those objects are being referenced by another object in my drawing (my pipe network). I have tried refreshing, resetting the working folder, all to no avail.
I want to change the reference surface for a pipe network with existing pipes and structures. however the changes will only affect new objects, I have to manually change the others one by one. Even with the vista open I can select multiple structures, but when I click in the reference surface column of one of the selected structures, all the others are deselected.
is it possible to get the alignment name which the corridor surface is built from when the surface is being data referenced. in other word no corridor as the middleman.
the way i see it is when corridor suface is referenced, it becomes a regular surface and loses some properties such as parent alignment.
i am still using COM. maybe .net can do it? either way works.

How would I go about generating labelled points with xyz values at 5m intervals along a road alignment in Civils 3D 2014?
I have had a go with the AddAlign Labels command but could not figure out how to add an elevation value to the label. Also this method seems to require manual input for each label which is not practical as I will have have around 450 points to set out.
I have looked into the Stakeout Alignment Report, but this seems to require a survey database, which I don't have.
How to calculate the AREA of cut and fill analogous to the volume of cut and fill between surfaces, but instead only between the alignment and the road profile in the prolfile view. From what I've read of similar posts a few people have had the same question but have been instructed how to do it with volumes as opposed to area. Also how to insert a table of cut and fill area analogous to the one you can inset from the volumes dashboard.
It is 27 miles of waterline broken into 3 mile segments.The problem is with the profiles that have been cut. The existing ground surface has been sampled along the alignment and multiple profile view made from that alignment. When the alignment changes, the only way that the surface seems to update is to run the "profiles; create profiles from surface command again" at which point it adds a new profile into the profile views reflecting the current surface over the alignment, then the "old" profile must be deleted from the profile views. Everything is set to dynamic, yet certainly is not being very dynamic.
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 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.
In most cases threaded parts are designed without true surface (just cylinder with texture) thus part surface area is calculated wrong (less than it is i real world)).
any automatic way to get true value of threaded surface which is modeled in traditional (simplified) way?
I have a problem: when i scale objects (even if I do a proportional scale clicking "Shift" button), the program automatically modify the alignment and the form of the object. for example if i scale a "stickman" which is completely symmetric, finally I have a figure with arms of different dimensions and proportions. Im using the cs5
The problem is not about the stroke dimension, is the path that is modified.
I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.
I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.
I am trying to add points into a surface. I have done this before without any problems, but now I am having issues.
When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.
I select the surface and use the 'edit surface command' in the ribbon, choosing add point.
When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!
I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.
The surface imports correcty, but when I try to import points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.
I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.
The questions:
Would it be better to import the surface into Revit to merge surface and buildings together?
Would it be better to import the buildings into C3D to merge entities?
Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?
I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.
Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?
My problem added with pic ... I want to make volume calculate for sample road project. When I try to compute materials I cant use Corridor surface for DATUM... There is only target surface on option..
I am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
