AutoCAD Civil 3D :: Grid From DEM Contour

Nov 21, 2013

When I create a grid from our OSIP DEM files the contours come in as a block. I usually do 1' and 5' contours. I would like to break these so that when I select a 1' contour it will show up individually with elevation data still attached. If you select one now, it selects the entire grid. If you explode it, you lose the grid file. Is there a way to do this or will a just have to label the contours so I know where I am at?

AutoCAD Civil 3D :: Grid Volume - Changing Grid Spacing

Jan 18, 2012

Understanding that composite volumes are typically more accurate, I have a reason to evaluate the volume between two surfaces via a grid volume.  Easily created a grid volume surface using a 50' grid (50' is large for this site, but wanted to get a feel for calculation time).

Question: Can you change the grid size without creating a new grid surface?  Ultimately I woud like to explore the difference in volumes based on grid sizing without creating a long list of surfaces.  One would expect that you could chage the grid spacing in surface properties, but the values are non-editable.

AutoCAD Civil 3D :: Contour Labels 2

Sep 20, 2011

When generating a line of contour labels with Contour-Multiple, most of the labels are orientated properly but some of them on the line are rotated 180 degrees. Why aren't they ALL orientated in the same direction?

Also, sometimes, all of them will be orientated in the wrong direction such that they are, essentially, upside down. Is this a bug or is there a setting to adjust?

AutoCAD Civil 3D :: Contour Labeling

Jul 10, 2012

I have recreated two surfaces for my design, existing and proposed.  I had used polylines for contours for in each surface.  I tried labeling the contours but it will not let me select the contour itself. 

I then tried to make the contours to 3d polylines and again added them to the surface and rebuilt.  I still am not allowed to label the contour since it doesn't let me select the polyline.  I am able to select the surface however.

AutoCAD Civil 3D :: Contour Labels Will Not Add

Dec 16, 2013

I am using Civil3D 2012 and have a drawing that will not allow me to add Contour Labels.

Unable to create contour labels

Issue You were unable to create contour labels. When you tried to create a single contour label, you could not select any of the contour lines of a surface. When you tried to create multiple contour labels, the contour label line disappeared after you selected the second point.

AutoCAD Civil 3D :: Contour Lines All One Entity?

Sep 15, 2012

I have a client that just started using C3D 2010.  When I sent him a topographic survey with contour lines (I am also using C3D 2010) he called me and asked if there was a way to select an individual contour line and have it display the elevation in the 'properties' dialog box.  I have not been able to find an answer for him.

AutoCAD Civil 3D :: Surface Contour Extraction

Apr 27, 2011

I have a drawing set to UTM83 Zone 14 Meters and my drawing units is set to meters also. I created my surface from my point cloud. When i do the contour extract feature (surface object extract), the contours elevation is in the wrong datum or elevation? The surface contour is 620 but the same extracted contour says 188.97? Curious why this happens. It seems to me that it is back calculate elevation or datum to a different coodinate system.

AutoCAD Civil 3D :: Contour Labels Not Showing Up?

Dec 20, 2012

Im working with 2013 Civil 3D. I have a site with polyline contours that have assigned elevations. I created my surface from the contours but when i try to label them with elevations, nothing. I label them by contour-mulitple with interval. All that is inserted are tic marks at the designated interval.

AutoCAD Civil 3D :: Contour Label Truncating?

Mar 23, 2011

how does one go about truncating surface contour elevation labels so they only show up to the tens place on the left side of the decimal (i.e. 50.25 instead of 5150.25)? I tried changing the rounding option under the style edit to "truncate" but that did not appear to change anything...?

AutoCAD Civil 3D :: Contour Lines Not Showing

Jan 3, 2013

We recently received a LiDAR data in the form of an .asc file.  Brought it fine into Civil 3d. 

However, the level data is in mm so levels are showing as 98450 instead of 98.45.  The level ranges from 98450 to 166260.

When I create a surface and set the style to show contours, it only displays contour lines below 100,000.  Is this a limit in Civil 3D or am I missing some setting somewhere?  I'm using the UKIE template btw.

AutoCAD Civil 3D :: Contour Label Intervals

Feb 25, 2013

It must be the medication, but I just can't remember something I learned in the last couple weeks regarding contour label intervals. I've been using C3d 2013 for about a year now and had used LDD 2004 until the upgrade.  I've become pretty comfortable with the styles based implementation now.

What exactly controls the numeric value shown in a contour label? I've got them looking fine on my site. I imported my styles and settings to a coworkers site but for the life of me I cannot remember what I had to change to get the contour labels to show increments of 1 foot (they were showing fractions of a foot)… Typing the word "fractions" triggered my recall.  The problem and solution was in the drawing units.(Inches vs feet).

How much time I spent looking through the style settings in search of the one setting I was missing... both times!  One of the best ways to push things from short term memory into long term memory is "Increased active practice". 

One thing I learned this time:  The style settings are not always the source of the problem.  It could be something very basic. It may save time to check the basics first.

AutoCAD Civil 3D :: Contour Label Line

May 31, 2013

I have been creating contour surface labels, which utilize a 3-point  contour label line with grips to adjust, and this is my question:

when i create a single contour label, clicking specifically on a contour i want labeled, the contour label line with the 3-grips extends beyond several contours and thus places a label at every contour it touches.  i can manually fix this by shorting the line, but this seems very inefficient. 

1. is there a setting to have the label only placed on the center grip of the three?

AutoCAD Civil 3D :: Contour Line Labels

Jan 23, 2013

I have my existing surface data referenced into my production drawing. I am trying to label the existing surface contour lines in the production drawing. I only have one surface in this drawing right now, so, I don't believe this is a multiple surface issue.

When I try to add single and multiple contour labels to the existing surface, I cannot select a contour line. I try to click on a contour line, using osnap, and I just keep getting prompted to pick a contour line.

AutoCAD Civil 3D :: Contour Labels Change

Jun 26, 2012

I have a drawing containing a surface with contour labels. There are two tabs representing two separate drawings. On one of the drawings I want to change the viewport color of some of the layers so certain features will plot lighter than on the other drawing.

When I change the color of a layer within the viewport, however, the masking on all the contour labels takes on a color (not associated with the color of the layer they're on, or anything else for that matter). Once the masking takes on the color, you can't undo it. You have to exit the drawing without saving it and call it up again in order to have the labels appear properly.

AutoCAD Civil 3D :: Add Contour Information To Corridor

Jan 10, 2014

I created a corridor utilizing a profile, assembly and alignment.  Worked well.  I then created a surface from that corridor.  The surface type should be displaying contours, but I do not see any.  What am I doing wrong?  The corridor display shows it covering the area that it should cover.

I did this once before and I had trouble with it that time as well.  I remember the fix had something to do with adding code data from the corridor to the surface.  I used a "+" button, but now have no idea where I did this at.

I am having problems viewing my contour lines after I create a surface. I create the surface using points.  The contour lines will show up when I create the surface. After I close the program or the drawing, I am not able to see the contour lines again. The contour lines are on in the surface style.  How can I see the contour lines without creating the surface again?
