I created a surface based on survey data, recently i recivied an updated survay (new DTM).
Is there a quick and painless way to update the surface? Obviously this surface is the basis for my entire design 8)
In 2012, the survey cogo points no longer seem to update after browsing to the observation data, making an edit and then saving. It worked fine in 2010.

I am using AC3D 2014. I have created a surface from downloaded DEM points, but, as expected, the contours are not as accurate as I would like. They vary from known elevations anywhere from a few inches to several feet.
I also have survey data from approximately 500 points which include Northings, Eastings and Elevations. Is there a way to add these points to my existing contour surface and incorporate these know NEZ points such that he contour surface is more accurate?
I have already converted my "known point" file to a .txt format with comma delimited information.
I am working on and manipulating the data may need to be done using the translate survey database command in the next couple weeks. The surveyors are waiting on some boundary info., which may not be available for a week or so. I have all the points inserted, and line work is done. How I go ahead and build a TIN surface, what tools ,if any are available to rotate a surface after it is originally built. The surface will have to adjusted to match the new location of the points when adjust the data.
View 4 Replies View RelatedEvery week I recieve new survey data (typically around 20 points) to insert onto an existing surface of our local landfill.
The surface is displayed as minor and major contours. The new survey data typically always has higher elevations then the exist surface and shot roughly 2 meters apart.
Here's my issue...when the survey data is inserted and the surface is rebuilt, the contours seem to turn into little cones at each new point. see attached...
how to eliminate these 'cones' so the surface contours seem more relistic?
I have a drawing with some cross sections of road showing the Proposed road surface and Existing ground surface. Now we have received a new ground surface and we have to supersede the old ground surfae with the new one. is there any way to swap the surface in the existing cross sections?
View 5 Replies View RelatedI created a surface in 2013 for an old project by importing a TIN from LDD, which worked fine, but the survey crew recently went back to the same site and did an update (asbuilt) with updated elevations. A good portion of the survey is still accurate and has not changed, but there was an area of new construction. My question is what is the best way to remove the old TIN lines (that are actually still connecting some old, incorrect survey points) and incorporate the new elevations that will now reflect new TIN lines in certain areas. Basically, I need to get rid of some old TIN lines and replace with new and updated survey. The surface in LDD used a point group, which was fine then, but now some of those points in that point group are incorrect.
View 5 Replies View RelatedI have a surface based on a point cloud. I decided to add a few more tiles of data to the point cloud and was expecting that the surface would update (after rebuilding) to include the new extents - but there was no change. The surface doesn't have any boundaries or breaklines but does have edits.
Do I need to add points to surface again? Will this duplicate the orignal point data or would it just add the new data. I didn't want to lose my edits if possible.

I am starting a Job in 2013 for the first time. Upgrade form 2011 C3D. The pipe structures are no longer updating when the surface updates. It will obtain an elevation from the surface when the structure is created but when I change the surface or even set the structure to a new surface, the Top of Casting will not update. Any thoughts as to whether or not this is a 2013 issue or if there is a new setting I need to change? This worked perfectly in 2011. I didn't use 2012.

View 1 Replies View Relatedhere's my process:
1- Import the asc file into my drawing.
2- Convert the asc file to a FBK file
3- Import my FBK file. The survey figure linework generated doesn't overlay my previously imported asc file. I checked the FBK file and the coord's match the asc file. I'm confused as to why the survey figures don't overlay the survey points from the asc file, since the coords match in both? The survey figures are all shifted .7' and 54deg. from the points. The elevations are all good on the survey figures, as they match the survey points.
So my quick fix is to explode the survey figures, since I don't really need them for what I'm doing, and then select all the 3d polylines and move them to them to an appropriate survey point. Everything then looks fine and I can get the job done.
However, I would like some insight as to why this might be happening. It's strange that the FBK and asc coordinates match, but the survey figures aren't lying over them.
is it possible to create a surface quickly in Autocad using 3d survey points on a DWG?
The way I did it was 3dpolylines and then lofting the surfaces. Quite time consuming.
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!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
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.
Is there any way to change the referenced surface on a Surface Elevation Label. I can see the surface in the properties but cannot change it.

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?
View 2 Replies View RelatedMy 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..
View 2 Replies View RelatedI 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.
We process survey data using Attributes to add extra intelligence and reduce errors.
For example, when shooting trees, the RAW file will contain something like this:
SS,OP 50,FP1299,AR308.2057,ZE91.0918,SD128.282,--TREE
FC,PN1299,FNTREE
AT,TNSZ,TV11.0
AT,TNTY,TVMAPLE
or when shooting a street sign:
SS,OP 50,FP1437,AR324.1135,ZE91.4728,SD123.235,--SIGN
FC,PN1437,FNSIGN
AT,TNTY,TVNO PARKING
The FC code sets up that attribute information will follow for the point number indicated by PN and the FN is basically explaining the name of the feature type. On the collector, this is all menu driven, making for few data entry errors.
The AT codes list the attributes name TN and then the TV reports its value.
Is there a way to preserve these attributes and their data when processing them into an FBK? Ideally, they would need to become part of a point description.
When processing this for that "other" CADD package, I am able to use these values in building labels for my survey points.
I was curious what the basic workflow is for creating an EG from a survey. The catch is that we don't have a point file or elevated points on the drawing. The drawing is just that a drawing with spot elevations and linework. The lot is 100' long and 30' wide. An existing house takes up most of the lot with a street on the front and back. The idea is to try making a grading plan after I figure this first part out. Where would I begin with something like this to figure out the next step of grading a small lot?

Now I have a serious problem, and cannot add any new Networks. The "Name" and "Description" appears, but there is no place for a cursor entry.
Do I have to re-install the program?
Is there a way to have cad automatically create a survey point when a surface point is added manually?

i have a point file specifically a PNEZD file. when i import points into the survey database the coordinate in the database is correct but the coordinate on the drawing tends to be 5 feet off one way and 1 foot off the other. When I import point through the points pull-down menu the coordinates are correctly shown. When I import point into survey database from drawing the coordinate is incorrect in the database but correct on screen.

View 5 Replies View RelatedMy company has upgraded to new computers recently (Windows 7, Civil 3d 2012). Some of the new computers are unable to access ANY survey database for edit. They can be opened read only, but the option of opening for edit isn't even available. The old computers we have CAN open the same databases for edit. We have attempted repairing/reinstalling, but to no avail. All the new computers were cloned from 1 original.
