hi.
is there an easy way to calculate (better to say let the program calculate) cut and fill quantities from polylines?
i want to get something like a 3dmodel / volume based on contour lines (each contour line is made of several polylines that are not joined an have gaps in between. but they are on the correct level / z coordinates).

one volume for the existing and one for the designed landscape...
in the end i need all the cut material seperated from the fill-material.

last time (when i used autocad not map3d) i had to join all the polylines into one closed polyline (=one contour line)to get the area. and do this for each contour line and so on...
a lot of work which i hope is several klicks with map3d...

i am also thankful for links. i didnt find anything useful or didnt search for the right words...

thanks a lot
cheers

If you have now Map3D you might use command _MAPCLEAN to get the polylines connected and to fill gaps between them, as long as the tolerance you need to fill the gaps is not to much to connect the wrong polylines!

Map3D has no options for calculating cut-/fill-volumes. The better application for that would be Civil3D (when you want to stay AutoCAD-based).
