AutoCAD Map 3D :: Contour Elevations From Shape File?
Aug 16, 2012
I downloaded a bunch of GIS files for Baltimore City and am trying to compile them to make base tiles we can use for different projects. I have tried using MapImport and MapConnect to bring in the shp file for the contours. They come in but without the elevation. The elevation is brought in as Object Data with MapImport, but is there a way to assign that to the elevation field in the polyline properties? MapConnect brings the elevation in as part of the table but again how do I get that elevation assigned to the elevation field in the polyline properties? I just assigned the elevations manually for the 10' contours in one tile. I have to do about 50 tiles, and it seems like there must be a much better way to do it.

I have an interesting problem. I have imported a shp file from a state agency. This file contains contours for an area. When I tag the pline, it shows a "zero" elevation, but shows a numeric elevation within the DXF_ELEV feature.I am needing to convert these to pline with elevation to work on in autocad. how to get polyline w/ elevations to export from c3d?

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?

Using C3D 2010. Drawing looks fine in model and paper space. When I try and plot (or plot preview) contour labels are gone! How frustrating. They will not show up again unless I restart C3D and open drawing.

I'm somewhat new to Civil 3D 2013 and have never encountered this problem before. I've got a top slope standard breakline (dark green line) and bottom slope standard breakline (light green line) with the highest elevation for the top slope at 72' and it gradually slopes down to about 54' within a 75' span. My problem, as you can see in the screen shot below, is I am getting 54'-59' elevation contours right next to a survey point with a 72' elevation whenever I hover my mouse over one of the contours. There are no nearby points with anything near 54' even outside of the surface boundary (shown in magenta).

I am working on three different projects at once. For each project, I was sent a drawing with contours as polylines. Each contour is broken up into polylines about fifty feet long each at elevation 0. I am trying to set the polylines to proper elevation without editing each one individually. Each drawing contains several hundred polylines to modify. I was hoping for some sort of way to use a fence and interval (2') with a starting elevation.
I've searched the internet but haven't found a lisp routine to do this. I thought I remember Land Desktop having something like this, but can't seem to find it in Civil 3D 2012. I have found several threads asking the same question. Each time the poster was referred to a blog 7629. That blog unfortunately seems to have been taken down. If I can’t find an answer soon, it looks that my best option would be to retrace each contour which makes me glad to be paid hourly.

Is there any way to apply a gradient like this...
to the wavy "lines" in a shape like this...
The shape is a compound path with a black fill & no stroke. Alternatively, is there any way to convert that shape to individual horizontal & vertical wavy lines?

i already know that in order to get a gradient to follow the outline of an irregular shape you could do a "blend" with smooth colour'
T he problem I'm having is that it's an involved process and most of the time requires too much tweaking - the points in both shapes should be the same and should approximate each other's distances btw the location on both shapes. I'm wondering if there's another, more direct way to, let's say, take a letter and get a falloff gradient in the shape of the letter...
just realised that a drop shadow might work....i need the gradient to eventually become a mask...

Contour on a bitmap shape.
I thought this was doable. Today I found it's not, or stopped working.

I am working as the civil engineer on a design team for a building that is primarily using REVIT. My site design is done in Civil 3D in real world coordinates and elevations.
Unfortantely, the architect and the rest of the design team are working at 0,0 with a finished floor of 100. When I bring in the ADSK file, I can move it horiztonally to match my site but I can't figure out how to move it vertically so it ties in with my model.

I am trying to edit the elevation of a JPEG image I have brought into my C3D 2010 file as an xref - I essentially want to 'drape' the image over the existing ground surface I have created to use for presentation purposes i.e. to show how our road layout is predominantly located along the ridge lines of the site.
Typically for other file types I would perform the following steps (using the classic toolbar): Grading > Edit Feature Line Elevations > Elevations from Surface > Select the existing ground surface > select object.
I don't seem to have the ability to select my jpeg xref using this approach... how else can I perform this task?

I'm using Autocad 2013 and i have a file with contour lines, with set elevation (z coordinate). I need those elevations to be visible - i mean i need their elevation in a text box near each line. Something like this - [URL]........ How do i go about it?
I've attached the file i need to do this with.

I need to create a truncated contour map based on data from a .asc file. I have connected the .asc file but there is no option for adding with query so I have brought the whole file in.
I then created a contour layer and added to map (all good so far) but when attempting to query this layer for my area of interest nothing appeared on screen.
I then did some manipulation of the sdf to create polylines at the contour elevation and tried to MAPTRIM but I stopped Civil 3D after having "not responding" for 15 minutes

I have a shape file representing sewer lines between manholes. I need to assign an attribute to the line with "upstream invert" and "downstream invert" in my table. Can I edit the shape file in map? I know I can edit in arcmap, but i am much more comfortable editing in acad. Then I could use arcmap to view my shapefile.

If there is a way to export a CAD file (dwg) to a shape file that can be imported into ArcMAP.
We use AutoCAD 2012, and do have Civil 3D, however have not used it (all of our dwgs are with CAD, not 3D).

I am currently using AutoCad Map3d 2013. I am trying to export some features to esri shape file. When I use the export command it does not export all the features, only a few of them. I tried each different way point, line, polygon (treat closed polylines as polygons). I just did this the other day and worked out fine.

How to compile a "master" .shp file that would include the coding for all of my shape files for custom linetypes. I did this years ago for a specific set of linetypes but I can not remember how I did it.
I know ACAD has the linetype.shp file that includes coding for ACAD supplied custom linetypes.
I think I remember inserting all of the shapes into a drawing and somehow compiling the *.shp file. Is that how it is done?

I am trying to import a Shape file and extract the attribute data associated with the 'lines' (sewer pipes) into text format.
for example a pipe has an attribute showing the pipe diameter and intead of having to manually type it out I would like a way to extract that information.
Is there a way to do it? Whether using a specific method during the importing of the Shape file or another process?
*I use AutoCAD Map 3D 2011.

I would like to know how to export a hatch shape as a shape file so that it can be used in ArcGIS. I am running C3D 2013 with Map 3D and ArcMap10. I have tried the Output as SDF and the map3d export and I haven't been able to get either to work. I don't have a problem exporting lines, points or polygons.

I've just installed 2013 and everything is good apart from. When I start up AC it runs through it routine and then asks for "Select Shape File".
I can point it in the right direction, but this comes up at every boot up and I would like it to find it automatically and my old memory can't recall this happening with 2012 or before. I am using an old template file, does that matter?

GPS'd fire hydrant locations. The GPS points were exported to shape files and using Data Connect, these points locate correctly in Map (using version 2009). The points have default styling...color, shape...and I want to use a CAD block of a fire hydrant to symbolize the points instead of the default square. Is this possible?
Clicking "Style" on the Display Manager to open the Style Point dialog box.
Next to the heading "Symbol:" clicking the ... button brings me to "Select a Symbol" pop up dialog box.
Next to the "Symbol Library:" drop down box, clicking the ... button brings me to the folder located at C://Program Files/AutoCAD Map 3D 2009/Sample/Symbols. There are 13 DWGs in this folder all called "Map - something.dwg" like "Map - electric.dwg" or "Map - water.dwg.
I can open any of these DWGs and they all provide multiple symbols to choose from in the "Select a Symbol" dialog box. However, none of these DWGs contain a symbol for a fire hydrant.
What other folders can be navigated to, in order to find other blocks? Can other CAD blocks be used as shape file symbolization or does the prefix "Map - xxx" in this folder mean that only these specific drawings will open for shape file symbolization?

I have a user who is trying to plot several design drawings which all have a connection to one shape file. The file in question is used as background data for the design and is apparently fairly large. When he plots the drawings only part of the shape data comes through. Based on the information I have it sounds like the software does not have enough time to retreive all of the shape data before the plot data goes to the printer.
