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 :: Create Block With Attributes That Automatically Complete X / Y And Z For Insertion Point Of Block?

Feb 14, 2013

Is there a way to create a block with attributtes that automatically complete x, y, z, lat, long for the insertion point of the block?

I am trying to complete text in paperspace that will automatically fill in the lat long of a point in model space without using a table.  I have tried field insertion with reference to a cogo point, but it doesn't give options for position on a cogo point.  If I pick a block with attributes, it will let me pick any attributes, and x,y position for the block.

Cogo points show all the information I need to propagate in the properties....but how do I get that to translate into the text using fields or some other method?

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 :: 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.

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 :: 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 :: 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 :: Create Surface From OG - Show Only Two Elevation Contours

I created a new surface, pasted my OG surface into it, set the build to exclude elevations less than and greater than but my surface still is showing every contour range. I want to only show contours at elevations of  371.5 and 370.5

Is it because it's a pasted surface?

AutoCAD Civil 3D :: Elevation Bandon (2D) Surface Style Is Missing

I've created a triangulation volume surface to compare two surfaces. Under the analysis tab in Surface Properties I have banded my levels in metre intervals and coloured the bands accordingly. I would now like to display the 'banding' in my drawing. Under the information tab I should be able to select 'Elevation Banding (2D)' as a Surface Style, however this is missing and I can only select 'Standard'... How to get this selection back.

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."

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 :: Unwanted Rounding Of Elevation Values When Exporting TIN Surface To DEM

Jul 7, 2010

My workflow consists of building a point cloud object from a LAS file, filtering it for ground data, and and building a surface object with it. Breaklines are inserted into a surface object, and then the surface object is exported to a DEM file to be used in a GIS application. The problem is that Civil 3D rounds the elevations to 1-foot intervals, even when the file is structurally floating point. How to override this rounding to get floating point values that reflects the original data?

AutoCAD Civil 3D :: Custom Color Scheme For Surface Elevation Display

Sep 19, 2012

I want to color cut/fill using red/greens schemes.

I want to use "interval with datum" method, and 2' intervals.

That gives like 20 rows for cut and fill, and so c3d applies one red to 5 rows, then next red to another 5, and so on.

I could pick colors by hand, but that dumb dialog is so slow, and its not easy to visually pick a nice gradation.

Is there no way to say "step from this color to that"?

Even when I do get all set up, I am finding performance of displaying the 2d solids takes forever.

I obviously have a large surface, but that is why we pay for good software right?

I am on c3d 2012 on a fast 64 bit win 7 machine. [URL]
