I am trying to create a bollean operation with boolean Sop, but touchdesigner only allows default geometris when I try custom geometries with file in Sop it throws an error saying the geometry is not closed, I tried to make it closed based on the wiki help, but it didn’t work pls anyone help. 
Hi @Clinge0,
the Boolean SOP is quite selective in what geometry can be used. Can you post a sample of the geometry you are trying to use? You might have to use a third party tool to edit the geometry before using it in TouchDesigner.
cheers

Ahh I tried some downloaded geometries, it didn’t work also TD default geometris which comes with file in also don’t I am trying to find a way to make them closed
