Hello everybody,
Never done that procedure. Bringing surveyed Cross Section Data to Civil 3D. Final goal is to make a surface out of it, so ideally feature line or point cloud.
Things I have:
-alignment;
-chainage;
-CS data.
CS data format
CHAINAGE 0+000
OFFSET R.L.
-17.4 510.8 Approx (Creek Flow Level)
-11.4 510.8 Approx (Creek Flow Level)
-1.0 510.8 Approx (Creek Flow Level)
0.0 510.8 Approx (Creek Flow Level)
3.5 510.8 Approx (Creek Flow Level)
4.3 510.8 Approx (Creek Flow Level)
4.7 511.3 ROCK / BOULDER
5.4 512.0 ROCK / BOULDER
6.6 516.3 ROCK / BOULDER
6.6 516.4 ROCK / BOULDER
6.7 516.4 ROCK / BOULDER
7.0 516.4 ROCK / BOULDER
9.1 516.6 ROCK / BOULDER
9.3 516.5 ROCK / BOULDER
Thank you,

Sections in Civil3d are simply a representation of real features, like surfaces and pipes. You cannot create them directly - you have to create the source data. In this case you may be able to create points from your source data files.
Try the CREATEPOINTIMPORTFROMFILE command.

If you have an aligment along the section, then you could use the text file to generate a profile (from file using station and elevation) along that alignment. The profile could, in turn be used to generate a feature line.
I tried to use feature line table for that but it doesn't support copy/paste procedure.
Actually I just got an idea. HEC-RAS support such thing so I can export alignment and CS to HEC-RAS.
Copy/paste values and do export to Civil 3D!
Just need to test it)

I believe the Civil 3D, Import from file will give you what you want. Look at option 5. This is what you have listed. Make a text file and assuming that you have an alignment to set these points to. Run the Import From File. Points set in the drawing to make a surface.

From Civil 3D Help:
I do this quite a bit. My procedure is:
1. Organise the data in Excel so that I have Station Offset and Elevation columns. The offset is with reference to the alignment
2. Save as a text file (no headings, just 3 clean columns with values only.)
3. In C3D - Create points (alignment, from file)
4. Pick the stn offset elevation option, the delimiter, etc.
5. You should now have all your cross section points. you may need to adjust annotation scale to see them.
As long as your cross-sections are appropriately spaced, you can get a reasonable surface simply by adding the points to a TIN surface. If your sections are too far apart and the alignment goes around a bend, then obviously you will get errors. You can make this a bit more acceptable by drawing 3Dpoly lines connecting points between your cross-sections and adding these as break lines - if you have a valid method for doing so.
If you post your text file then I'm sure it will be easy to identify the invalid character issue.
Cheers

Vasily:
I must make a slight comment to what Mick said. Based on what you originally posted you will need 4 columns. Station, Offset, Elevation, Description.
You may have to enter the stations manually since it does not appear on each line. However, I will agree with Mick that putting your file into Excel is the best way to get all of these columns in a usable manner.

If you have any problems, post your text file here and someone will critique it.
Khalil,
You'll need to organize your data into a more usable format, like this:
200,-8,78.242
200,-6,78.429
200,-2,78.362
200,0,78.502
200,1.5,78.432
200,3,77.072
200,5,75.842
200,6,74.889
200,10,73.079
Because there's no Northings and Eastings, you'll need to create an Alignment before you can import those Station and Offset Points.
