Dynamo Topo / Top of Foundation Script

[Einar_Raknes]

Here is something to get you started @Kieran_Atherton:

To convert the topo to a dynamo surface I used the code from this post:

Topography import to Dynamo

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