Surface color by point and value

I’m trying to color a surface by point (extracted in previous analysis from the surface) and value but It is not working and I don’t understand very well the node. I looked everywhere but couldn’t find solution. Thanks in advance.

In “select faces” node, it should give one surface if you select one face. In your case, you selected two faces. The list it is giving is 4 nos. Please give an info about the surface that you are picking in the model. I hop, the surface input is where the error occurs.


Do a “List.Flatten” after the Select faces node and supply the resulting list to the “Surface” input in the faceanalysis display node.

I got it running… I made topography from point and then i got surface from the topography and it worked but it still dose not show colors.
