TIN

[Rommelme]

If i have a road design with table drain along side, how will I extract TIN for the road alone and not to include that of the table drain ?
The TIN file is to be used to run a simulation in the 3D Office (of Topcon).

The easiest way is to build the normal total model and apply a new boundary to it.
All you have to do is plot the 2D strings and make a closed polyline from the LEB and REB lines - then add this as a boundary to the surface.
