   I want to import geometry from
a Autocad Civil 3D 2010 file to HEC RAS, but I have some conditions.
My CAD file has no surface,
but it has points. Some of them belong to cross sections and others are in the
alignment (Talweg), especially in curves. Therefore this points in talweg (the
ones which do not correspond to cross sections) define the curves.

I have also 3D polylines that
defines the alignment and the banks.

So, I want to export the
geometry with these curves and not to have straight lines between cross
sections, as the following figure shows.

Thank you very much!

	In a brand new EPSG:5345 drawing, load the attachment thru the _LANDXMLIN command: what happens? uploads/249910/San_Miguel_de_Tucuman.zip
