problems exporting mesh to ecotect

Hi

I am having trouble with the simple tashk of exporting my mesh to ecotect... It looks like all the mesh is loading(in ecotect)... but then only ends up with one panel...

The mesh was previously a panelled surface, so that might have something to do with it..

I have tried uv mesh and brep mesh.. but still doesnt work.. I need to make sure ecotect is acting on the mesh as 1 singuar mesh not panels.

Any help is always greatly appreciated!
