AutoCAD Civil 3D :: How To Color Contour Relative To Elevation
Dec 11, 2013
I would like the contour line colored to reflect the elevation it is depticting! I have successfully used surface properties - elevations - to create ranges, and to FILL color in between contours, but is there a workflow to color the contours themselves?
I also noticed, within the same dialogue box in surface properties, a contour pull down - but it doesn't have near the control to set elevation ranges, nor does actually effect the contour color.

I have a grading that, going left to right has a a region of relative elevation, a transition followed by another region of relation elevation.
I need to change criterior of the transition region to another relative elevation with the appropriate transition on either side.
I deleted the original transition grading (with the menu commands) and tried adding the 3rd relative elevation but keep getting prompted for a transition length instead of the relative elevation (I am choosing relative elevation criterior). It seems the feature line doesn't want to let go of the original definition. I should be able to replace that original transition with a new criterior, No?

I was given a file from a competetor (this is evil)
The file has coordinates in feet (x, y) but elevations (Z) in meters.
I need the contours intact (cant explode block and scale) to create a surface from.
The other part is this is a big file so anything by hand would be rediculous.
I need the final file where the x,y has stayed the same but the z has been adjusted to the correct foot elevation (scaled)

Is there a way for Civil3D to create/generate/extract a contour of a specific elevation such as 105.53 from an existing surface?

Is there a way to change or create a new scheme (banding) by elevation? For eg. I would like to use only a range of grey no other colors.

I want to import a shapefile into acadmap; this file has contourlines, and in the attribute tables there also is the Attribute for the elevation of the repective line, noted as integer number
after import all lines are on elevation 0
how can I filter all those with same elevation attribute, change them to an AutoCAd object (polyline) and have them moved up to the respective elevation which can be read out from the attribute table?

Of course with ACAD MAP (FDO Labels for example) or better with ACAD CIVIL : no problem !
But often I have to use a Standard AutoCAD ...
A lots of people have already asked for this routine :
But I search in this forums and some others and unfortunately I can't find any correct routine Full operational on ACAD 201X 32/64 bits
I have many 2D Plines with an Elevation : some Normal , some have been splined --> 1st problem
I would like to label them with :
- either a Block with ONE attribut : the elevation
- either a MText with a blank Mask behind
As you wish ...
Question : Size/Height of the Block or MText ?
Some 2D Plines are very long (2nd problem) so I would like a question like :
Label each Pline every xxxx Units ?
So on a Pline Contour of 2000 meters, I could have the elevation (Block or MText) every 50 meters ...
Of course I would like that the Block or Mtext will have to follow (rotation) the Pline (splined or not) where the label is inserted !

Is there a setting I can change so if I am drawing an object (line, polyline, etc.) if I am snapping to a contour line, the objects will NOT take on the elevation of the contour line?

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 trying to create an elevation label that will give me the spot elevation followed by the letters "TC" and then on the line below subtract 4 inches from the elevation followed by the letters "BC". It's easy enogh to add the letters but the simple equation of elevation - 4 inches eludes me.

When I snap a point to an object, the point takes on the elevation of the object. I would rather the point's elevation stay as is.
-changing osnapz variable
-latest civil 3d service pack
A few weeks ago I did not have this problem but once my computer was switched to the company's global server and c3d was reinstalled the problem appeared. Furthermore (post switchover), when a colleage of mine prepared a simple test drawing with just a line and a point, he was able to snap to that line without the point changing elevation. When he sent that drawing to me and I tried snapping the point to the object, the same problem occured with the point taking the elevation of the line object. I suspect it is a system variable issue

i have some existing drainage pipe and structures in a base plan that i need to change the invert (which is the easy part) and the top elevation to the existing top elevation that does not meet the minimum presect in civil 3d 2012 is there a way to change these min. to match my exisitng elevation for example i have a catch basin invert is 15.45 top is 17.56 with a 18" rcp the cover will be less than 12" and i need to change this.

I can't get it into my head the difference between Absolute color and relative color. I've been told many times, but I still can't remember. Would anyone know the difference, and any further reading?

Periodically, when I try to create an XREF using the Relative Path option, C3D will tell me that it can't use the relative path. But if I then close the drawing and reopen it, the command works just fine. why C3D sometimes fails to do this, or why closing and reopening the drawing fixes the problem.
Never saw this problem before C3D 2012.

i found a way to get a report of my cogo points relative to an alignment i.e. station offset. problem is, i have thousands of points in my drawing. is there a way to get only a few, or a group of points to show up on the report instead of ALL of them?

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?

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.

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?

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.

This seems like something that should be really easy but for the life of me I can't figure it out. I even started looking at using the Subassembly composer to create a custom SA but that seems like a ton of work so something that would seem to be a common problem.
I need to provide a v-ditch with 2:1 side slopes at the toe of a 2:1 fill slope. The flow line of the ditch should be 2 ft below the daylight point of the roadway pavement section.
My problem is that the conditional subassembly seems to evaluate the height of fill directly beneath the attachment point of the conditional SA (pavement section daylight point in my case – “Daylight_Sub” Point code). Instead I need it to evaluate the difference in elevation between the catch point of a 2:1 daylight fill slope and the conditional SA attachment point (Daylight_sub). If that difference is less than 2 feet, I need to provide the ditch, otherwise I can just use the daylight slope for the ditch foreslope and the existing surface for the backslope.
how to do this? Maybeits as easy as using a predefined daylight subassembly that I'm overlooking?
Here’s my current assembly attempt:
And the resulting behavior. It is solving the 2nd fill condition when I would like it to solve the 1st fill condition:

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.

Is there a way to quckly join contour lines that have been broken where the contour elevation is?
example, if this were a contour line ---------501---------
I'd want to delete the contour elevation and join the line to make a continuous contour line.....

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.

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.

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...?

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.

I’m having some issues with my CAD. Every now and then, my contour lines disappear and I can’t get them to reappear. My surface border and triangles will appear but not the contours. Sometimes if I change surface styles they will appear but other times they are gone forever.
Troubleshooting: Regen AllAuditPurgeLayers on/offLayers frozen/thawedPromoting (if the surface is a data short cut)Changing the surface styleChanging the contour interval
None of this has worked…
