The BlenderBIM Add-on moves fast.
I've taken a step back to think about the overall direction I would like to see the BlenderBIM Add-on, and its associated suite of utilities (IfcClash, IfcCSV, IfcDiff, BIMTester...). I'd like to share the roadmap with others: https://wiki.osarch.org/index.php?title=BlenderBIM_Add-on_Roadmap - currently, the software suite is still at the beginning of the journey!
For those interested, there is also now a changelog: https://wiki.osarch.org/index.php?title=BlenderBIM_Add-on_Changelog
