[IfcOpenShell] Condensation of B-Rep geometry

1. S by Shilpa on 27 Jul 2022, edited 5 Aug 2022 #

   Hi Moult

   I extracted B-Rep geometry using geom module in ifcopenshell library.

   There are around 150 vertices retrieved for one manhole. I want to check if there is a way to condense it in a meaningful way. I am extracting product and geometry data into a knowledge graph. I am not sure if storing 150 vertices for one manhole is a viable option.

   Appreciate your thoughts.

   Thanks

   Shilpa

   I don't understand what you mean with condensation

   @Shilpa can you share the IFC file here, i might be able to show you how to reduce it via BlenderBIM.

   @theoryshaw id be interested in seeing how you do that as well, any chance you'd be up for a screenshare maybe? @Coen I think @Shilpa meant to simplify the geometry, ie reduce the polygons/vertices.
