Hi,

Trying to use a clipper for 3d intersections but some 3d solids getting rejected i think due to geometry errors in 3d solids. I have ran the 3d solids through geometry validator but does not fix the geometry errors. Geometry errors include - Non-Planar Surfaces, Incorrect Solid Orientation, Invalid Solid Boundaries. Any other ideas to fix? Thanks

GeometryValidator is the main tool for identifying and sometimes fixing 3D solid errors, but it doesn’t always repair complex issues like non-planar surfaces, incorrect solid orientation, or invalid solid boundaries

  • SolidBuilder may help reconstruct valid 3D solids from surfaces and potentially fix geometry errors.
  • RebuildSurface to repair non-planar or invalid surfaces before reconstructing solids

Check the parameters in these transformers for options like “Force Planarity” or “Repair Geometry” to target specific issue

Thanks, I take it to turn to surfaces you need to de-aggregate using deaggregator - however this wont occur even if i flatten all levels and split composites.
