How can I filter some type of item out of a list?


I put together his graph I found at LandArchBIM blog, but something odd is occurring. The point list is polluted with some function items, and I don’t know if its only because of that, but entering this list at Topography.byPoints node results in a “3 point needed for create toposurface” kind of warning.

How can I filter the non-point items from the list?

You need to convert the list to comparable objects (likely strings in this case) and then compare them against your filter to get a boolean response. You can use that with FilterByBoolMask to filter the elements into passing and failing elements.
