I had a proposed surface in Civil3D2010 that was fine, made revisions to the proposed contours using grips or deleting/adding contours. Now when I try to add the new contour data to the surface either the program hangs up or I get contour error messages and the surface never gets re-built.
View 1 RepliesThe engineers at my company digitize proposed contours in a drawing and then they want me to create a surface out of the contours....the contours usually are 2 foot contours with areas that the software tends to translate based on the contours that I selected to create the surface.....I then usually need to create a profile, which does not look accurate compared to the contours, such as low spots etc...............
My question is since the engineers at my work do not how to use the software, and I am not an engineer, making the profile look a certain way sometimes needs to be tweeked by me.... How to alter the proposed surface?I am pretty sure that feature lines cannot cross contours that I have selected to create the surface?
I have a existing surface. I want to create a proposal surface so I can know the volume between boths. This proposal surface is represent for a disposal area that can be filled up to a elevation. I have a bottom of P-surface as a feature line at EL 1608, and I want top of P-surface to EL 1613.

I'm trying to create a proposed grade surface using the grading tools. I drew the outline boundaryof the proposed surface as a closed polyline then created a feature line from it and assigned different elevations to it. When I try to select the feature line in order to create the grading, I get "THIS FEATURE OVERLAPS ITSELF AND CANNOT BE GRADED". What could be a possible reason for this?

I have a profile showing proposed storm sewer, existing sanitary, rock surface, existing surface, and proposed profile. Today for some reason the proposed profile and labels, and the existing surface are not showing on the profile and I'm not sure what has changed or how to get them back.
View 3 Replies View RelatedWe have an engineer who is taking an existing surface and wants to show a proposed road 2" higher than existing.
I told him to simply adjust his assembly for his corridor to account for the 2" difference, but the County agency needs to see a profile.
My questions:
1) Is there a way to easily copy a profile made from a surface and "convert" it to a proposed profile? If we copy and explode, it turns into hundreds (thousands?) of tiny pline segments and it would be a mess to convert all those to a profile 1 by 1. If we make the corridor, and choose "profile from corridor", we do not have an option that could be used to represent the centerline.
2) Other than loss of dynamic updating), would it make sense to adjust the assembly so the top surface would be accurate, then copy the profile, explode the copy to a block and simply shift that (as essentially basic linework)?
I am trying to create a proposed surface using grading. I created a closed polyline representing the site's outer boundary then created a feature line from it. When I try to select the feature line in order to create the grading I get "THIS FEATURE OVERLAPS ITSELF AND CANNOT BE GRADED".
View 1 Replies View RelatedI'm a bit of a Civil 3D newbie. I've got a project that involves addition of storm drain to existing storm pipes. I'd like to be able to use Civil 3D to include existing and proposed pipes in the networks, but be able to show existing pipes differently than proposed pipes on plans and profiles, i.e. screened. I can't seem to figure out a way to do this--I can effect changes to all networks, but not invididual pipes.
View 9 Replies View RelatedI created DRefs to an Alignment plus the Existing and Proposed Profiles. I ended up with 3 alignments with one profile attached to each of the second and third alignment. The second and third alignments are name as <Alignmentname> (2) and <Alignmentname> (3). I deleted them an just brought in the profiles but they each created a new alignment.
I searched the board and Google. What I found was that it's recommended to keep the profiles in the drawing in which the alignment was created. I usually do that. But I've been working at a 1:1000 scale and now the Engineer wants the profiles plotted at 1:500. I don't like changing the scale in the drawing so I thought I'd created a new drawing with that scale. It doesn't look like I can do that now.
In LDT listing curve data was as easy as selecting an alignment, clicking edit and printing out a spreadsheet with all the required info. how to do this in C3D. Inifo I need:

I am trying to get the existing and proposed grade from my surfaces to show up in the center bottom of my cross sections. I am working with the CL elevations band style and trying to set up so that major and minor increments are the surface elevations. Am I going about this wrong? I went in to the compose label tab and selected for the text to be section 1 elevation and section 2 elevation. When I am at the section view properties box / bands tab, all that shows up is my existing surface. I have created sample lines and a corridor. I have also created a surface from the corridor.
View 1 Replies View RelatedI am at a crossroads with this corridor that I have to create in Civil 3D 2011, with a sub assembly that logically seems very simple...the conditions for daylight can be found in "Proposed Cross Section". In short I have 4 fill conditions and 2 cut conditions, based on height above original ground...(there are additional requirements for guardrails and retaining walls but at this point i will settle for my slope reaching original ground)
View 9 Replies View RelatedI 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 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.
I was wondering if there is a way to print proposed lines in color, yet still have everything else print in monochrome.
Currently we print using monochrome, but would like to have our proposed line work stand out even more by selecting them, and having them print out in color.
Is there a way to do this without having to set all the other layers to a grey scale manually.
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?
