I am trying to delete all interior partitions in this breps and end up with a final “shell” made only of the external parts of the brep faces.
As you can see, multiple surfaces are extruded and, therefore, interior walls are created.
I can’t seem to find and answer to this problem. Help will be much appreciated.
I’m afraid the region union option applied to the initial boundaries can’t work since every boundary has a different extrusion value.
I am considering a solution in line with deleting all intersecting faces but I can’t seem to make it work.
I am attaching the Rh/gh files as a sample.
You could probably create a loop and create a boolean union with the closest extrusion one after another. But I don’t know how to do that so my second attempt was to create point groups which would hopefully result in sets that union… Needed two loops and the resulting Brep has no naked edges. There are some manifold edges, which is no surprise when extruding ‘boxes’ with varying height and touching corners. Despite the manifold edges, the mesh could be printed.
Well, I’ve been trying to do that for the past two hours and I’m still left with three breps that don’t join in Grasshopper (but do in Rhino) and a bunch of naked edges (and surprisingly no non-manifold edges), so I quit !
Removing the inner walls is needed in order to perform an energetic simulation.
If inner walls are present, results can differ quite a bit from reality.
Anyway, thank you for your interest and work Martin, I will review your answers and try figure it out.
