AutoCAD Civil 3D :: DEM Has X Y Coordinates In Meters - Z Elevation In Feet
Oct 22, 2012
I'm trying to create a surface from a DEM (as a *.adf file)
How to convert between coordinate systems. (a UTM system to a State Plane)
How do I control the elevation values? My DEM has x,y coordinates in meters, but elevation values are in feet...
So far what's happening is that I end up with all the z values multiplied by 3.08... (I assume it is trying to convert the meters to feet..., but since I already have feet in the DEM ... no good)

I'm a GIS analyst trying to learn Cad. I'd like to place a single point in autocad model space at a specific Northing/Easting position. After reading several forum threads I don't think CAD allows me to change the coordinate system of model space from map coords to northing easting coords, as we can in GIS.

I have a set of dimensions in meters and I am trying to automatically convert to feet. So I am going to the Dimension Style that rules the numbers that I want to convert and after clicking in Modify button>Primary Units I go to Linear dimensions group and change the Unit format from decimal to Architectural and 100 m turns to 8' - 4" not to 328.08'.

I have been sent a DWG floor plan from a firm in South America. The existing file is Type: Decimal and Units to scale: Meters. We need to convert the file to a useable architectural and feet set up. I know that I will need to scale the existing dwg however I am not sure what the exact steps are or what I should scale it by. Should I change the drawing units first and then scale? Or the other way around? Biggest thing I need is the scale factor.

I imported a shape file drawn with a utm signature with the dbf and shx files associated with it.The field map looks exactly like it is supposed to but when i dimension different places the dim are in what i think are utm measurements( ie .0069).When i draw a line at say 200 feet the line is astronomical in comparison. I can't seem to figure out where to change the scale.I have never used the auto map before and am using the trial version.

I recieved a drawing in which the coordinate values are a thousand times too high; they are in millimeters and I need them in meters. I checked the settings of the drawing, and it clearly says that it´s in millimeters, but it doesn't change the setting or to copy the whole drawing into a new file with meter settings.
How I can change the coordinates to meters?

i am trying to translate a Point coordinates from Paperspce to world coordinates in model space.The code i used in Land2006 worked OK but now in Civil3d 2012 it doesn't!

Dim lole(0 To 2) As Double, upri(0 To 2) As Double

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.

Is there a way to make AutoCAD2012 display the area of a closed Polyline as Feet- Inch(ex 22'-4") rather than the feet as a decimal (ex feet=22.3333333) as it does when the units are set to Architectural or Engineering?

I have browsed one file in meters from Pythagoras to dwg. When I opened it with Civil 3D the drawing units become feet. Where is the problem and how can I convert the whole drawing to meters?

I have a very simple surface. All of the elevations defining it, are set in feet. When I click on the surface it tells me my max and min elevations are in feet matching the points that I have defining the surface.
Here is the kicker, when I run a distance it is measuring the Z distance in inches and not feet. As you can see by the attached image the distance is 95' but the elevation change is 1 3/8". The actual points defining the surface are 1.28' difference. If I were to do a spot elevation on the surface, it would give me the correct elevation in feet. I am guessing that this is some sort of variable that I have missed, but damned if I can find it.

I have a drawing in metric but I want the results in feet and inches, do I draw it in metric and have Autocad spit out a feet and Inches drawing, is that even possible. Or do I do the conversions up front and explain to the client that he will get his metric drawing back in feet and inches.
Second part, if the drawing is in metric do I open the Autocad Civil 3D metric icon or does it matter. Where I can read up on why there is a metic and imperial Autocad icon?

We are having a bit of a debate in our office. When you are working on civil engineering project where you are recieving files form Architects and Landscape Architects, and sending out "Dumbed Down" AutoCAD files to folks who don't have Civil3d, do you change your Civil3d Coordinate System to survey feet & specify your state plane coordinate system?

Any way for Vol. calcualtions to be shown in Acre Feet? I am doing Volums of lakes and the client needs a report of the number of Acre Feet in the lake. To get the data, he uses a depth finder hooked up to a GPS. I can do this by hand calculator but using Civil 3D 2013 would be much easier.

In Civil 3D 2013, when I execute the _area command, i get results in square feet as opposed to acres. Under the ambient settings, the area unit is set to acre. how to get C3D to display my area in acres? I just want it to list the area, not label it.
Also, is there a way to get it to display the area in BOTH acres and square feet?

I have an alignment and have station labels. The alignment is labeled with "Major Stations" at every 100 feet. I need to change the station increment to 25 feet and have labels. I have done this although station 1+25 is still reading 1, station 1+50 is reading 1, etc. There is a precision variable somewhere, and I can't figure it out. I have played with the alignment labels style but no luck. Is there a global drawing settings somewhere that might be controlling this?

I was just wondering why when I try and calculate an area using a polyine, I am getting a readout of 1.80401967E+07, when I have it set to give me the calculation in square feet? It is an area of approx. 246 Acres.....is this because the area is so large? I am not sure what the "E" stands for or the "+07" at the end....

I've got the Pipe Table style just as I need it except for one thing. I have all circular pipes and I would like the "size" column to display in inches rather than in feet. In the past I was able to multiply this number by 12 in the style composer but that doesn't seem to work anymore.

I am in the process of transitioning from land desktop to Civil 3D. I design roads in steep terrain and sometimes need to have my catch (daylight) slopes change. So my question is, how do I change a daylight slope at a specified depth? For example, from the shoulder of the road I want a 3:1 fill slope to a depth of 10 feet than change to a 2:1 slope until it catches the existing surface. Can this be built into a subassembly such that if the fill is less than 10 feet it will daylight correctly at a 3:1 and if the depth is greater than 10 feet then it carries the 3:1 for 10 vertical feet and then changes to the 2:1 until it daylights?

I have GeoPDF that I can't attach properly to drawing in Civil 3D. So with Global Mapper I exported it to geo-referenced ECW. I checked ECW in Global Mapper and ArcMap, everything just fine.
However when I did mapiinsert in Civil 3D, image appeared with shifted coordinates. The original coordinate system is BC/Albers and coordinate grid is Lat/ Longs.
