I work in both Microstation(PowerCivil) and Autodesk(C3d 2010) platforms, unfortunately not very proficient in either. We use both due to project requirements. I have no say in the format what-so-ever. Now to the point.. I am working on a project thats survey is a 2d .dgn however I am to create a model from this information (which happens to be just text spot elevations no intelligence attached) and supply it in C3d..Is this Possible ?? Or would it be easier to just do it in PowerCivil (I have made surfaces with 2d objects before with) and convert to .dwg upon completion ????
You need 3D information to create any surface in Civil 3D. You can get 3D
information from your 2D text by using the tool specified in the attached
image. You would then add drawing data - text to the surface.

If you need more than spot elevations you can use the DTM tools in Power
Civil to extract the graphics to a TIN using the interpolation option. It
will read contour labels and apply the text values to the contours or
breakline vertices. From there you can export to LandXML or ASCII or put the
TIN triangles in a DWG for extraction in C3D.
Build the model in Power Civil if you understand that process, then
export a LandXML file.
Import the :LandXML file into your Civil 3D drawing.

By the way, if you have the survey project file that goes with the DGN you
can create a TIN from the survey project. Look for files with the .prj
extension in your project folder. You also may have the TIN files already
made. Look for .TIN or .dat files in your project folder. It is possible the
.prj, .tin and .dat files were stored outside of your project folder so you
might need to do a search on your network or talk to the people who made the
DGN. Also be aware that many applications create .dat files so be discerning
if you find .dat files in unlikely locations.
Depending on the type of 2D data given you might like to try TopoGX.

If the 2D Data includes text levels and insertion point indicators like
point/cross/block-insert then this tool will be able to automatically
determine which cross the text is supposed to be assigned too. This even
works when the indicated insertion points move around relative to each
text so does not require X,Y offsets.
It will then assign the appropriate levels to any appropriate 2D line
work on the drawing creating which can then be used as breaklines
creating a much better 3D surface.
It can then be imported into Microstation or Civil3D (via 3D DXF file)
for any additional work you might like like to do with it.
