You have a Land Desktop drawing containing points. You want to convert the points to Civil 3D points. You also want to keep those points on their original layers. When you convert the points the Civil 3D points are all on layer V-NODE. How do you keep the original layers?
Civil 3d installation help and product documentation in web, pdf, and video formats.
Autodesk has posted YouTube videos on installing Civil 3D. It covers both Single User Stand-Alone licensed and Network licensed versions of Civil 3D. Links to Installation documenation for Civil 3D 2011 is at the bottom of this post.
From the AutoCAD Civil 3D 2010 User Documentation… Opening a Land Desktop Drawing
Land Desktop data is not automatically converted to Civil 3D objects Geometric data, such as contours, quick sections, grading objects, and curve text, are displayed in AutoCAD Civil 3D as Land Desktop objects. For more information, see the Civil Object Enabler Help
Civil 3D cannot read the LDT Contour data directly
AECExportToAutoCAD Creates Plines with elevations
see also Using the Object Enabler The Object Enabler is available on the AutoCAD Civil 3D installation CD and on the Autodesk web site at www.autodesk.com/aecobjenabler.
see also Drawing Sharing Command Reference in the Civil 3d help file. It lists all the commands such as ExportToAutoCAD2010 and each command’s description.
If you need a specific file version and you are running just AutoCAD there is -AECEXPORTTOAUTOCAD2000 or -AECECPORTTOAUTOCAD2004 or eTransmit with the option to explode AEC objects will give you the same results.
Using -PURGE (the command line version of PURGE) and choosing RegApps option will also clean out unnecessary Registered Applications that may cause stability problems with your drawing.

Brian Kling from Autodesk describes the hardware, software, operating system characteristics that affect Civil 3D performance. This was published in 2009 so it addresses Civil 3d 2010. Civil 3d 2010 is only available as a 32bit application. Civil 3d 2011 is both 32bit and 64bit compatible.
Subassembly Studio by CADArtisans allows you to create custom .NET parametric subassemblies for AutoCAD Civil 3D. This subassembly show in the video was created using Subassembly Studio V1.04 from Cad Artisans (www.cadartisans.com)
This subassembly consists of a fill slope that intercepts a target surface. If the horizontal distance from the insertion point to the intercept point exceeds a user-specified MaxWidth, a retaining wall is inserted at the MaxWidth and the slope is reconstructed to target the back of the retaining wall. This subassembly was created in approximately 8.5 minutes from start to finish, including importing into AutoCAD Civil 3d and inserting into a corridor model.
The primary strategy when creating subassemblies is to first create the positions and behaviors of points. The links are defined next from a list of points. The shapes are defined from a list of links.
Autodesk has created a video outlining ways you can improve the performance of Civil 3d 2011. It discusses performance tests comparing Civil 3D settings for points, surfaces, labels, corridor models and more. You won’t find any discussions on hardware, operating systems, or AutoCAD settings. Those topics are covered in a related post.
In this post I want to show you that exchanging data between Civil 3D and Carlson Survey is relatively easy. I made two posts today about transferring data using LandXML. Additionally, in this blog post at Carlson Connection you will find that working with Civil 3D data in Carlson/IntelliCAD is not such an impossible chore. Carlson Survey for example has a command to convert a Civil 3D or Land Desktop surface to a Carlson TIN file.
