We have created a surface made from corridors & breaklines. During the initial surface creation process the surface appeared to be fine, but as we went thru and started doing edits and adjustments of the corridor the surface is starting to added erroneous points that are created spikes in the surface. The attached image shows what the surface is doing.

View 1 Replies View RelatedMy corridor surface randomly bounces from top links to bottom links through the intersections even though I specified top links only and my corridor is modelling correctly.
Previously I just deleted the surface and recreated it with no errors but it doesn't seem to work now. This happens with both manually created intersections and ones created with the intersection tool.
I am having an impossible time smoothing a surface created from feature lines in the attached file. I can smooth the service in parts except for the area that I’ve hatched – as soon as I try to smooth that area the drawing freezes or I get a fatal error. Ideally I’d like this surface to smooth to a 3x3 grid.
The things I’ve tried:
- Exploding the feature lines to 3d polys and recreating them as feature lines before adding them back to the surface.
- Copying the feature lines to a new drawing and creating a new surface
- Completely deleting the feature lines and manually re-drawing them from scratch before adding them to a new surface.
- Adding the feature lines with different supplemental distance and mid-ordinate distances (typically I do 2’ and 0.01’ respectively)
- Smoothing the surface in sections instead of one global smoothing of the entire surface (it always fails when I get to the hatched area)
- Smoothing the surface with different grid dimensions.
- Emailing the drawing to coworkers to see if they can create the surface and smooth it on their computers
- Combinations of all of the above.

I have downloaded ArcGrid (ADF) files from the USGS and am trying to define a TIN surface in Civil 3D with those files. I have done this in the past without difficulty but now I get a fatal error and the system crashes in the middle of the process. The ADF files are large, approximately 465 meg, and cover an entire USGS quad area. Is there any tricks or sollutions that would allow me to use this data source to create surfaces without my system crashing?

Surface does exist as we can see the triangles/contours or whatever we choose to display. When we run the Water drop command, we are getting a message saying that the point is outside of the surface. We have selected a valid surface by both picking it visually and selecting it from the dialogue. All layers are on and thawed and we are picking well inside of the surface.
Why it would be telling us that the point is outside the surface?
I am working on a 6 mile highway project whose surface file is 85MB big. So, I created a Data Shortcut of this surface and used this for creating profiles. However, at some locations the corridors go below the surface(as per their original profile) which was not intended. So, I need to restrict the surface to follow the corridors but not go beyond it.
I have created feature lines from corridors and tried to add them as breaklines to the surface. But " error adding breakline" error pops up.
Is it because I am trying to add the breaklines to the mirror surface which I created from Data Shortcut ??
Will it be useful if I copy feature lines to original surface file and add these feature lines as breaklines in that file??

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 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.
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?
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.
Trying to patch and then sculpt an area on a pipe so that it blends together better, however it keeps coming up with an error. The strange thing is, it shows up in the preview after selecting all the edges but then does not calculate correctly.
Basically trying to fill the 2 small areas between the visible workplanes. Also, I couldn't get the project cut edges in the 2 sketches to only project the curves I needed, so all the cylinder edges are projected.

Attached is a surface model with parameters which drives an assembly I have. I was testing it by changing dimensions to see where failures in the main assembly occured. It worked for a few changes so I saved it and checked it into vault.
The Split using the 70 Deg Plane (you will find them in the browser, Split 5 and Split 7) is where the problem occurs. When I increase the outside diameter (i made it 147 in.), Spits 5 and 7 get moved up to the top half.
The same surface (named OUTER HOUSING SIDE) and its mirror are split on the XZ plane prior to the splits in question (5 and 7).
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?

When importing objects into Inventor, all surface objects are being joined together into 1 composite surface. What I need is multiple surfaces, or seperate surface/composite objects.

Each solid is a sepreate solid
Capture 2
Shows 2 solids and 1 surface composite imported from Rhino

1. Why is Inventor creating 1 composite from multiple non intersecting surfaces?
2. How can I avoid this from happening?
I keep getting this message. I know others have posted about it- but back int 2006 [URL]. The referenced link showing the solution is no longer available.

I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
If I change a point or link code in one of my subassemblies, is there a way I can build my top surface using those?
