LINEWORKSHRINKWRAP will create a boundary from a group of closed polylines. It will be flat. The problem I see with making a 3D polyline would be: what happens when lines cross. What elevation would be used for the vertex?
I export a civil 3d surface in autocad. Then i convert the 3dfaces to 3dpolylines.
I want to make a boundary using some of these 3dpolys.(i set another layer for pave, gutter and slopes and i want a boundary around of each set)
I try also the bpoly command to create a 2d poly. I explode the 3d polylines to lines and i set all z to 0. But the bpoly command make autocad to crash.
So i need something to work like bpoly but not crash, and if its possible better something to create a 3dpoly from surface 3dpolys.
If you have the C3D surfaces use shrinkwrap as Peter suggests and the use the Elevations from Surface command which has a Multiple object selection option on the pline(s). You will be left with 3dpolys.
I need to slow down my typing.

That should be a bit easier to read.
Copy and convert the inner bounding 3d faces to regions by typing _.region into the command prompt. Select one region and right-click. Choose Select Similar and then type flatten into the command prompt. Now type bo into the command prompt and, because you have lines at constant Z, a 2d boundary can be created. Now apply step one from above to get 3d poly.
may i ask you something else?
Is there an option to export for a corridor surface triangles in different layer or color for eatch component e.g different for pave different for slopes etc?
