AutoCAD Civil 3D uses a text file with the .FLT extension to define breaklines (edges) for the digital terrain model. You can create this file in your text editor (e.g. Notepad).
Each breakline in this file starts with the code of the breakline type (most often "S"-Standard, "P"-Proximity) and contains the list of its X-Y-Z coordinates. At the end of line you can set the name of the breakline.
An example of a FLT file:
# Breakline file for Prague tunnel P1542.258750 179.318779 0.000000 Edge1-pavement 1190.721102 350.527660 0.000000 860.816542 446.044194 0.000000 588.600214 619.055276 0.000000 S1529.639450 179.318779 100.250000 Edge2 1188.918348 357.736453 101.420000 1021.998725 330.653391 103.530000 594.008485 610.044279 102.870000 761.574952 744.929530 104.780000To define breaklines by point numbers (not point coordinates) you can use the transparent function 'PN which converts "point number" to "point coordinate XYZ".
