AutoCAD Civil 3D :: Surface Sport Elevation Label Rotate

Jul 5, 2013

I have been searching for a way to rotate surface spot elevation labels but have not been able to find a solution to do so.  Has this feature been added to 2013 or 14?  I do not want to use the point and label styles for my surface elevation, even though these can be rotated.  I have several miles of roadway with many horizontal curves and would like the surface labels aligned with and along the centerline.  I prefer not to update the spot elevations when the profile is revised.

AutoCAD Civil 3D :: Surface Spot Elevation Label With Dynamic Location

May 8, 2013

I know that I can add coordinates for such elevation using text component editor but I have to add the letter "N" for North or "E" for East to identify the location of the elevation (North/East/South/West). But, is there a way to make a label style that reads up the location of an elevation automatically?

I've attached pictures below for this issue.

AutoCAD Civil 3D :: Can't Change Reference Surface For Pipe Network

Sep 4, 2013

Civil 3D data shortcuts. 

So I first created a drawing which included a surface called "CONTOURS" and an existing sewer pipe network. I then created a data shortcut of the existing sewer network and started a new drawing with a proposed sewer pipe network.

When I received better contour data, I created a new "10FT EXIST CONTOURS" surface in the existing sewer drawing and switched the reference surface for the existing sewer structures and pipes to the new "10FT EXIST CONTOURS" surface. And of course I deleted the old "CONTOURS" surface because I no longer needed it. 

Now, the part that makes me want to pull all my hair out! When I open the proposed sewer drawing I get all the error messages that "Reference surface 'CONTOURS' not found in reference drawing" for all 22 of the existing sewer structures.

I've tried deleted the existing sewer network in the proposed sewer drawing and recreating the data shortcut but nothing makes the errors go away. Is there any other way the existing sewer structures could be referencing the deleted surface that I have not thought about? How to get the error messages to clear?

AutoCAD Civil 3D :: Change Pipe Network Reference Alignment Or Surface

Dec 14, 2009

I want to change the reference surface for a pipe network with existing pipes and structures. however the changes will only affect new objects, I have to manually change the others one by one. Even with the vista open I can select multiple structures, but when I click in the reference surface column of one of the selected structures, all the others are deselected.

AutoCAD Civil 3D :: Reference Surface (x) Not Found In Reference Drawing

Jul 28, 2011

I am getting this error in my production drawings.

My setup is as follows:

- EG.dwg has my existing surface in it. I create a data reference to use it in other drawings.

- Level One.dwg has the EG surface data referenced in, and I use this to create alignments, profiles, and finish surface. All of these are turned in to data references.

- Storm Sanitary.dwg has my pipe designs. I data reference in the two surfaces, profiles, and alignments, and create pipe networks. I create references for these networks.

- Plan Profile.dwg is the production sheet I'm getting this error from. Every one of my civil objects is data referenced in to this drawing. Everything is inserted correctly, the pipes show correct FG surface elevations for their rims, etc.

BUT when I open this drawing, I get this error. I assume it's because my FG surface is not directly in the storm sanitary.dwg.

How do I get rid of this error, without combining drawings, or promoting the surface to one or more drawings? Isn't this exactly what data references is made for?

AutoCAD Civil 3D :: TIN Surface At Zero Elevation

May 22, 2013

I used the Volume dashboard to cal volume so when I view the surface in object viewer or 3D I see my TIN volumes surface at zero elevation is this right? I think the reason is because they want us to see both surface so they are not on top of one to another.

AutoCAD Civil 3D :: Surface Elevation Labels

Jun 26, 2013

I have a drawing that someone else created that has a spot elevation label for a surface. It labels the surface (PAD) then automatically subtracts a set distance for another elevation (GFE) and adds a set distance for another elevation (FFE). After doing some research, it looks like it was created with an expression?

I have two questions:

First, where to go to get a better understadning of this? I'm not familiar with expressions.

Second, where can I find the expression in drawing to make an edit to the set distances. I can remove the GFE/FFE as they are separate components in the label style, but I don't see where to modify the distance it adds or subtracts.

AutoCAD Civil 3D :: No Elevation When Hovering Over Surface?

Apr 25, 2013

I have created a surface, when I hover over a contour on it I used to get name,style, layer, elevation.  Now I get them all except elevation, I didn't change anything (not on purpose at least) in my drawings.

AutoCAD Civil 3D :: Surface Analysis By Elevation?

Feb 8, 2006

I've tried to create a surface analysis by using a point group reading xdata to set the elevations and when I set my surface properties to display the elevation shades it will only allow me to set the range to 5 or less. All of the other analysis settings for direction, slope, and slope arrows allow me to input the nuber of ranges I want, but I need the elevation analysis.

AutoCAD Civil 3D :: Surface Transparency (elevation)

Apr 17, 2012

In the previous C3D 2012 version I was able to set surface transparency just setting it on a layer with defined transparency. Example: I set my "existing ground" surface to a created  "EG" layer (example name) and set transparency layer to 50% (example, again) and it WORKS! My surface become transparent...

But now, in the C3D 2013, I can't get the same results... my surface is not getting transparent. I already tried to turn off/on hardware acceleration and adaptive degradation and show/hide transparency.

More details: I can get transparency on points, triangles, contours etc... but not on elevation, and this is my priority.

AutoCAD Civil 3D :: Surface Elevation Labels

May 3, 2012

We work with Hydro graphic surveys that have large numbers of points. We would like to be able to display girded spot heights colored to represent the elevation. (Similar to elevation banding)

I have created a surface and then created surface elevation points on a grid with spacing of 15m. I have tried looking at setting up a style  that will adjust the color depending on the elevation ie 0 to -1 = red but haven't made any progress.

AutoCAD Civil 3D :: Block Attributes Surface Elevation

Feb 18, 2013

I got this plan from a third person and, the point from the survey have the property " bloc ". In their attribute property, I can see the elevation value. but in the z of the actual bloc, it shows zero. I would like to tell C3D to use the attribute elevation for his actual Z in the drawing. How can I achieve this ?

AutoCAD Civil 3D :: Export Surface Elevation Values

Nov 15, 2013

AutoCAD Civil 3D :: Elevation Colors In Surface Style

Jun 24, 2013

I have a surface with all sorts of heights, and want to add color to different heights. Getting the color there is not that difficult, but how do I swap them around? i.e. red is 'low ground' and blue is 'high ground'. In Holland we use it the other way around though, so blue should be low ground and red high ground. 

Where exactly do I change this? I've tried it in the surface style tab, surface properties tab, analysis tab, and some others, but no success so far.

AutoCAD Civil 3D :: Elevation Banding On Flat Surface

Jun 19, 2012

I am using Civil 3d 2012 and an trying to apply elevation banding (one color) to a surface that is completely flat. Everything seems to be in order but nothing shows up. If I add another point file to it that has a variety of elevations then the elevation bands show up, if i remove it it disappears again. I can view the boundary and get elevation readings when I mouse over the surface.

I just used 8 points to create a surface - see the right-hand-side of  the 1st attached file.

I went to Settings => Surface => Label Style => Spot Elevation =>Elevation Only => Label Style Composer - Elevation Only => Text  Contents: <[Surface Elevation(Uft[P2[RN]AP[SN|OF]>P<[Description(CP) - see the 2nd attached file.. 

I went to Prospector => Surface => Surface1 => Definition and I did not see any place for editing Elevation - see the left-hand-side of the 1st attached file. 

How to make the Elevation and my stuff in Description show up in the DWG.

AutoCAD Civil 3D :: Sample And Extract Elevation From A Surface

Feb 27, 2012

I just got a topographic map of some land we plan to develope, and would like to work out some preliminary earthmoving analysis.

I would like to sample that surface at very specific locations --  I could produce the required points in PNE format.

What I want is to find the way to: (1) import those points, (2) sample elevation from the surface at those locations, and (3) export the 3D poitns in PNEZ format.

AutoCAD Civil 3D :: How To Delete The Broken Surface Reference

Jul 19, 2007

I have got the ole Program Errors Dialogue back again. It seemed to stem from a rogue data shortcut that got broken.

I could not delete the broken surface reference, so had to create another data shortcut, create a reference and then I had the opportunity to delete the rogue surface and then the data shortcut.

Anyway, I got this error on Audit. (see image attached)

and this was the audit command line dump...

Command: audit

Fix any errors detected? [Yes/No] : y

Auditing Header

Auditing Tables

Auditing Entities Pass 1

Pass 1 100 objects audited

XData String Length 260 > 255

could not be repaired.

I may have made an error by importing a data shortcut I didn't need in past weeks on this job. When a data shortcut is broken, it is quite hard to remove the reference.

Anyway, perhaps I just need to upgrade but I don't want to do it for this curent project as I am almost finished. (famous last words).

So what is causing this error that cannot be fixed? I didn't ask foran Xdata string to exceed 255 characters...

AutoCAD Civil 3D :: Data Reference Surface Disappears

Feb 21, 2013

I have a Surface that is data referenced into many different drawings. On one of the drawings, the reference will not show contours until I sync. It will show the boundary. Just one of them...but I can't use sheet set manager to publish drawings since I have to open it up and sync. Is there a setting we changed? The styles are all the same. The surface is on C-Surface, the boundary is on C-Surface, the Contours are on C-Surface-MJR, C-Surface-MNR.

AutoCAD Civil 3D :: Reference Surface Profile Linetype

Aug 27, 2012

I have a drawing with multiple profiles.  We originally had an existing and finished ground surface in the drawing, but decided to use a data shortcut to the surfaces as the design kept changing. We deleted the old surfaces from the drawing, and created the data references, using the same surface names for the new referenced surfaces. 

The ground lines show up in the profile, but I can't get it to show the linetype I need for the EG surface (dashed).  It doesn't act like a typical profile line - it now shows a lot of PVI points, and plinegen settings have no effect.

AutoCAD Civil 3D :: Different Surface Cross Slopes And Super Elevation

Mar 6, 2012

Our provincial standard requires subgrade and subbase surfaces to have a normal cross slope of -3%.  The base and asphalt surfaces have a normal cross slope for the driving lane of -2% and -5% for the shoulder.

I have been trying to figure out how to do this in C3D.  I have thought of different ways of handling this for a straight tangent, but have not tested them.  What is causing me the most grief at the moment is how to handle this in a curve with super elevation.

The transition will be different for -2%, -3% and -5% Runout distances. 

Can C3D handle this? What about using Subassembly Composer?

(I should mention that I have tried with Subassembly Composer, but I am not sure how to deal with superelevation.  -

AutoCAD Civil 3D :: Elevation Banding Surface Not Displaying Properly

Oct 21, 2013

Today I created a TIN Volume Surface. The volume surface seems to have a "resolution" issue if you will when displaying using elevation banding. In the attached screenshot note how the edges of the surface are "squared" or pixelated. Also, the blue lines are "hide" boundaries, and they have the same effect. I've created volume surfaces before with no issues until now. 

The volume surface compares 2 surfaces that were created from nothing but contours. Some of the contours can be seen in the attached image.

I've tried REDRAW and REGEN, the image looks the same in model space and paper space, I've tried closing AutoCAD and reopening the file. I deleted the volume surface and then created a new one... I'm sure there's just a setting somewhere that I'm missing. 

For comparison, also attached is a screenshot a "normal" volume surface that I created before. This one has no "hide" boundaries, but the edges of the surface aren't "squared."
