I have a surface in Civil 3D which when I opened today is not displaying. All it shows is to border of the surface. I know the surface is there because it is still listed under prospector view and the points are still there. I have tried all the usual things; checked contour layers is on, checked contour interval etc.

I created some about 20 cross sections for a creek we topo'd and then went to work making the topo itself look presentable. After I was all done with that I noticed my cross sections had lost the surface data and were now just an empty grid.
When I go to edit a cross section's properties in the elevation tab the "Automatic" choice has a minimum and maximum elevation of 0. When I use one of those existing sample lines to create a single cross section the same thing happens, it's not picking up data from the surface. However, when I made a new sample line along the existing alignment it picked up the elevations and created a cross section just fine.
Is there anything I can do besides recreating all the sample lines and cross sections? I'm looking for any other way because I have already labled and put in some extra work on the cross sections and I'm hoping to be able to just recreate what I already did and drop them so it will match the linework I already did.
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.
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 have a plan and profile sheet set up with two viewports in it. Somehow one of the viewport's frame disapeared and I don't know how to get it back. Since it is not showing I can't click on the viewport to unlock it and adjust the view. I also can't delete it.
View 3 Replies View RelatedMy 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?

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?
View 6 Replies View RelatedI'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?

How can I do this in C3D?
I'm trying to export a surface as a DEM so that I can import the object into Bryce 7.1. I have a number of sample DEMs that I have downloaded from USGS site that import into Bryce quite nicely. These samples also import to another DEM reader named "3DEM Version 20.7." I'm able to import into Bryce when I set the grid at 10, but the quality of this surface/object is not very good. The DEMs from Civil 3d are referred to as "USGS DEM"s, but they do not load on common DEM readers such as Bryce or 3DEM software. Any way of converting a C3d DEM to a USGS DEM that one of these other readers can import?

I've been wondering if there´s an easy way to copy a TIN surface or at least an easier way than what I'm currently doing. What I do is:
- Exctract objects > points/contours depending on the surface and border
- Create a new TIN surface
- Definition of the new surface > add point group or add contours
- Convert the 3D poly of the border to a 2D poly
- Definition > add border
I'm looking for an easier way that would save me the trouble of isolating the points or contous because my drawing has too much data and its very time consuming. Isn't there a command that lets me copy a TIN surface which creates another with the same objects as definitions?
I need to create a surface representing our site conditions in 1998. I have a drawing which consists of hundreds of "points" which are not really AutoCAD points, they are blocks (little ticks) with elevations assigned. How do I convert this into a surface without manually creating points on top of each block (i.e. clicking hundreds of times).
