AutoCAD Civil 3D :: Draped Image Doesn't Fit Surface
Dec 18, 2013
I've brought a PNG image into a Civil 3D surface model and attempted to drape it on the surface. The image is scaled to the topography when it's first brought in, but when it's draped on the surface it gets placed very small in the bottom left corner . I've attached the same image to another surface file (without the regrading in this one) and it works fine. why doesn't the image drape over the whole surface?
I'm running into problems with Civil 3D 2010 trying to render a TIN suface with a draped JPEG.
I've inserted a JPEG aerial photo (supplied by municipal GIS services) and applied it as a drape to the TIN surface terrain model. When I go to the 3D Modeling workspace and try to render the scene, the following error message is displayed:
"This scene cannot be rendered. The scene must contain at least one 3D wireframe or solid model object to render."
The DWG co-ordinate system is UTM83-17. Sometimes these issues can be caused by objects being too far from the origin, and I've tried moving everything to 0,0,0 all to no avail. The surface style confirms triangles as being displayed in Model view, so I really don't know what the problem is here.
I have a georeferenced image which I have used to drape over a surface - so far so good
If I change to Realistic View the quality between the original image and the draped image is marked i.e. the draped image is dire and can't be used for a 3D view etc as the quality is so poor.
How can the image quality be retained when draping an image?

I have a project in vault (v2011), with surfaces, etc. data referenced into a sheet (neglect workflow for the moment) that displays correctly, print preview's correctly, but when plotted does not show the surface contours of any surface. Additionally, some contour labels and spot labels display CORRECTLY while some spot labels are ??? and some contour labels are not visible.
By the way, the surfaces are in different source files.
I have a corridor that uses the Urban Sidewalk subassembly along the streets. During my rough design phase I set the outside boulevard widths to 2.00, and create a corridor surface using the Top Links as breaklines. I then do my lot grading, using that surface as a surface pasted into my FG surface. All of my side yard swales go up to the edge of the corridor's boulevard, with the elevation set 0.20 below the corridor surface. Once all of the design is done, I go back to the corridor and change the boulevard width to 0, thus forcing those side yard swales to now go up to the back of walk.this creates a small depression where we place small drain inlets.
Herein lies my problem, when I change the boulevard width from 2 to 0, the corridor surface never changes to reflect the 0' width. It's as if the break lines that I told the surface to use from the Top links are holding fast. The ONLY way I have been able to get the surface modeled correctly is to completely delete the corridor surface and create a new one and recreate the boundary, which I then need to re-paste and move to the top of the Edits in my FG surface. Just deleting and readding the Top Links from the corridor surface definition does not solve this.
the corridor-created breaklines do not get revised when the corridor changes, and cannot be edited/deleted by the user. Perhaps I am doing, or not doing, something that is forcing these breaklines to persist..
I'm creating a 3d ramp and need to create one surface of the whole thing, but as its overlapping on certain areas the surface keeps attaching itself to the corridor below it and another corridor crossing over top.
how to create a smooth surface that doesnt connect to anything overlapping it?
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 have used the object viewer of my surface and selected conceptual visual style. I save the image as a .png file for a presentation. Is it possible to have the area that there is no surface to be black and not white? Other than opening it up in paint?
I am trying to import a surface and Image from Google Earth. Basically my steps are as follows:
start GE and C3D find area that I need on GE and zoom in under C3D, insert GE Image and Surface (then it goes straight into select point, and rotation)
Like most discussions i've read.., the import slows down at 49%, and then it chugs for hours if I let it. So i have to cut the cord and re-start both programs.
I saw in a discussion that there are settings that we can change the rows and columns to something like 70x70.
however.... I cannot find where to update this. I typed importgesurface, and clicked on the ribbon as well..., then tried to right click, but it does not take me to the settings. I also figured that I might have to run C3d as admin, but no luck either.
find these settings so I can change them to import a surface and image that is about 15acres?

I have no problem bringing my google earth image and surface into autocad civil 3d 2011...but when I do bring it in the elevations are not correct...I'm bringing in a google image that have an island over water.... the units are wrong even though i changes to units in autocad...what do I have to do in order for google earth to import the correct elevation into autocad civil 3d 2011 ?
I am trying to edit the elevation of a JPEG image I have brought into my C3D 2010 file as an xref - I essentially want to 'drape' the image over the existing ground surface I have created to use for presentation purposes i.e. to show how our road layout is predominantly located along the ridge lines of the site.
Typically for other file types I would perform the following steps (using the classic toolbar): Grading > Edit Feature Line Elevations > Elevations from Surface > Select the existing ground surface > select object.
I don't seem to have the ability to select my jpeg xref using this approach... how else can I perform this task?
I have successfully draped an orthophoto over a DEM in Map3D but the resulting quality of the the image is so poor it is unusable. I have attached a couple screen shots of the 2D and resulting 3D images. Is the resolution in 3D dependent on the 'resolution' of the DEM? The orthophoto is 10cm resolution.
I have tried REGEN and to Resample Raster but I haven't had any luck.
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.
Previously i`m using version 2009 and importing Google earth image and surface works fine. However, recently i tried with version 2010 and i`m having some problem here (imported surface / contour seems ok but the image is too large like 3x or 4x). How to solve that?
I was wondering if there is an easy way to trim one surface to another. Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge. Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.
If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?
After a few seconds in the program the menu with all the slides like insert,view,etc. somehow freezes. i can´t pick it anymore. the rest of the program is working,i can work on the work surface with the current tool, but choosing an ew one isn´t possible. i have this problem with different version 2011,12 and even 13....
I used a 2d polyline to create a surface boundary for a surface created. The polyline is a closed loop. For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.
My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary. If I don't have a surface boundary the entire drawing surface shows up no problem.
The purple polyline is my boundary and the light blue is the surface created within the boundary.
Is it possible to export created surface from civil to revit architecture? If yes , How? And if its not possible - maybe i can somehow import cogo points to revit?
