Selected element(TopoGrahpy) to PolySurface

[verdi95SZXJ9]

Hello.
I am trying to change the selected element(TopoGrahpy) to PolySurface by Dynamo.
But the node “Topography.Mesh” can’t recognize the selected element(TopoGrahpy).
I can’t settle this problem.
I appreciate your help

Hello, it seems that the subject is related to your problem.

Can't pick a toposurface and create a mesh from it

Not sure if this will work, but you could try to recreate the topography by extracting the topography points and then try to get a mesh from the recreated topography (with slightly altered points). [topo] Point.ByCoordinates(Math.Round(t.X,2),Math.Round(t.Y,2),Math.Round(t.Z,2));

Cordially
