Topography import to Dynamo

[Vikram_Subbaiah]

You could convert a Revit topography to a polysurface with this…
TopoSurfaces.dyn (4.0 KB)

iA=List.GetItemAtIndex(T.Mesh.VertexPositions,T.Mesh.FaceIndices.A);
iB=List.GetItemAtIndex(T.Mesh.VertexPositions,T.Mesh.FaceIndices.B);
iC=List.GetItemAtIndex(T.Mesh.VertexPositions,T.Mesh.FaceIndices.C);
//Surfaces
TopoSurf=Surface.ByPerimeterPoints(List.Transpose({iA,iB,iC}));
//Polysurface combining Surfaces
TopoPlySurf=PolySurface.ByJoinedSurfaces(TopoSurf);
