Hey everyone, I am trying to extrude the topography created using coordinates in the - Z direction to form as a solid below. I have converted the topography into a poly surface. But I am unable to do it all around the surface. Below shows the script and the model created. Please help me with this …

Hmm… As I say, that was the most robust method for me… I wonder whether you want to delete the code block line-by-line to see at what point it fails… Then we can maybe find an alternative method of doing it? Here’s the extrude the sides method… Topo3DPrint-ActiveView-SolidByLoft.dyn (39.3 KB) […

there might be something in this topic. [image] Thickened Topography Problem Revit Hi Wayne, Have a look at my answer here:

Hey, If you don’t manage this before… there was a workflow of patching a base and lofting the sides but it failed for me so… I found the most robust way to do this was to take the the edges of the topo, flatten them in their z axis, patch and extrude then split the solid by the original topo… i’ll…

Thanks mann! I will check it and let you know !

Hey, there is a slight change in the model. Now I am trying extrude the whole topography as a solid which will enable me to do the excavation in the topography. I have extruded the surface as a solid using thickness node, but there are a lot of cracks and peeling out of solid. I don’t know exactly …

Hey, sorry for the delay, it’s funny how your memory plays tricks, here’s the thing… There’s a node in Chynamo which does the work for you… I rebuilt the surface first to get more reliable results. Let me know if that doesn’t work for you… [Capture] Topo3D.dyn (12.9 KB)

Hello Mark , Thanks for the response . Unfortunately the node which you have suggested is not working. In order to find the exact error, I broke the node further here is the picture ! the error states “Unable to Loft” [image]

I made a very small script for it, you need the topography and a floor! After the script has been executed, the floor will be the topography. Who needs it can write to me, I can upload anything yet

This is my Script, you see it works :slight_smile: [Script] [Revit]

That’s a really great idea :smiley:

Thanks, I think it’s the easiest way.
