With Leica instruments the best way is to process the data using the Leica LGO software. It allows all the capabilities of the instrument to be used. Smart Station Setups( GPS), Free Station Setups (Orientation&Height Transfer,Resections, Knowen Az) to be used. Process in LGO save the processed coordinates as a PXYZD.csv file and import in to C3Dand apply description keys to get line work and point codes.
Some of the Leica Dealers will give you a copy of the Old LGO4.0 I wont work with the new GPS equipment but it will process the TPS data.
Without LGO export the data from the instrument as an *.RW5 file. Process the file in C3D use the SurveyDataCollectorLink. Its been 20 years since I worked with TDS data; the old software you used to be able to fake out by changeing the dictance to the backsight to a negative distance. To bring the coordinates to the instrument. As I recall with the DCLink Software you need to enter an extra Setup and Forsight with Inversed AZ and ZA and Rod HT and HI exchanged. (They used to call it Remote elevation in TDS)
The RW5 file will also have an Occupy line for each setup ex(OC,OP101,N nnnnnn.nn, E nnnnnn.nn, EL nnnn.nn) all of these need to be changed to notes except for the starting Takeoff Coordinates; or the file will not process. Process the data and export as either a point file or a *.FBK file.

Thank you for your info. I once asked out Leica reps why not process in LGO and they said that you can but most people process in C3D or InRoads-Microstation and just use LGO as a "middle man" so I more or less gave up using it to process. It always made sense to me to use it to process. I have LGO 8 so I'm good to go. Since the data is processed in LGO I can just export a PNEZD Ascii file to any CAD platform, like you mentioned.
Obviously a FBK works great for RTK GPS work but I always get errors in a FBK created from a TPS job.
If I export a .csv file with PNEZD or PXYZD, how do I get the linework control codes in the text? I could make a custom ascii .csv I suppose?

A good place to start is with the Leica Code Lists. Enter Matching Codes in the C3D DescriptionKey Sets, Figure Prefix Code Set, and Line Work Codes. Start with the Code Lists in LGO and make sure every thing matches exactly.
There are several vidios on youtube and at http://retrieve.rguidestore.com/ About seting up Leica with Civil 3D
It a good job for a weather day, it takes a while to test every code.
You can also use complex codes with custom user point files ex: PXYZDABCD.csv where additional attributes can be added to each point. ex: WELL OIL, PHILLIPS STATE #2, SWSW 16-26-72, API 32-234568
Import the csv file in to C3D2013 and click apply description keys in Toolspace. The points and line work will be put on the proper layers with the custom symbols and line types applied. No need for the fbk file.
Thanks. I have a very robust code list for LGO/C3D,sometimes to a dissadvantage, but I can change it as needed. I generally use FBK files but I did some exports from LGO to a .cst with comma delimination. I setup the control codes to match BEG, PC, PT, etc. It worked fine.
Leica uses C3 for 3pt curve which only works with a fbk import. If you use import PNEZD I don't see where/how it is possible to use C3 because the control codes for a PNEZD import uses both a PC and PT so it won't understand when to stop the curve. Outside of writing a custom program to replace C3 with PC & PT or abandoning using 3 point cuve on the insturment and strictly using the SPLINE command, what can I do?
I'm going to take your comments and do some trials with some topo. Thanks for you help.
On a side note, do you use the line and area code feature with Leica? I have tried it inthe past with fbk files but never with PNEZD. I have had limited success. I ended up going back to using only point codes. Mostly because I found it was easier to work with points only and have lines connecting the points in C3D. I'm open to explorig all options though.
