I’m creating union polygon from a triangulated mesh. Clipper works great for most of the data but some complex objects (34 000 triangles) take very long time to process (over 3 minutes) and profiling reveals that 96% of the time is spent in FixupIntersectionOrder() function. Does anyone have any idea/suggestion whether it might be possible to optimize this part of the code? Martin

I'm experiencing the same issue with doors as well using the latest exporter 18.2.0.0 and Revit2018 with default architectural sample model. The door guid is trully unique which goes accross consecutive exports. That makes the resulting IFC file useless for any feeback and further operations which would tie back to original Revit model.

Hi Angel, thank you for the response. I'd never guess that levels could come identical from templates. This solution is obviously the right one to keep unique ids unique. Thanks again. Martin

Hello, I work on an application which works with spatial structure of the building from IFC. I thought that IFC GUID of the IfcBuildingStorey is generated as a random GUID on every export but than I realized it is using ExporterIFCUtils.CreateAlternateGUID() while for all the other elements ExportUtils.GetExportId() is used (both in GUIDUtil.cs). These two guids are different. Is there any reason for this? Or could it use the same code as other elements with 1:1 mapping? Thank you for the response,...
