BlenderBIM Add-on v0.0.200525 has been released with yet another 30 new features and fixes. The BlenderBIM Add-on is 100% free and open source software that lets you author and document BIM data fully to ISO standards. Get it today: https://blenderbim.org/

Highlights include improved clash detection features, more robust round-tripping including object re-use, basic cove.tool environmental analysis integration, and new experimental IFCXML and IFCJSON support!

New features:

  • New feature to convert from local to global (georeferenced) coordinates
  • Custom Qto definitions can now be exported
  • IfcClash can now patch global coordinates to aid in accuracy of clashes
  • IfcClash can now be used standalone or as a library in any project
  • IfcClash is now bundled with the BlenderBIM Add-on for Windows and Linux (any Mac volunteers who want to build it?)
  • Exporting two IfcProjects will now merge them into a single IFC project
  • Experimental IFCXML can now be imported
  • The relative placements of the spatial hierarchy are now imported and exported
  • IfcClash now supports clashing many-to-many / multiple IFC files at once
  • IfcClash now lets users configure clash tolerance
  • IfcClash now reports the worst-case distance clash in the case of multiple clashes with the same two objects
  • IfcOpenShell now has a utility module to let you conveniently do geolocation, element filtering, and getting element properties
  • IfcClash now supports element filtering, with filter rules, and/or statements, inclusion and exclusion rules
  • IfcClash now supports internal collision checks - to check for collisions within a single group of objects
  • IfcClash now supports clash sets to be defined so you don’t need to setup the rules again each time
  • The BlenderBIM Add-on has a new UI to create and run clash sets with IfcClash
  • The BlenderBIM Add-on now has a feature to export and import clash sets
  • Simple integration with cove.tool for basic energy and daylight analysis
  • You can now export experimentally to IFCJSON format (Thanks Ioannis!)
  • BIMTester updated to latest MicroMVD syntax specification
  • BlenderBIM Add-on now allows you to specific relationship checks during IFC Diff execution
  • When importing the same file or updated files twice, existing rooted elements (spatial elements, objects, types, etc) are reused instead of duplicating
  • You can now export psets related to spatial elements
  • Users can now switch easily between IFC4 and IFC2X3 when exporting
  • New feature to select / highlight all clash results in your current 3D viewport

New fixes:

  • Rewrite IfcClash system to drastically increase quality of clash detection results
  • Fix bug where monetary units can cause an import to fail
  • Fix bug where an IFC without a subcontext can cause an import to fail
  • Fix bug when exporting / round-tripping IFC2X3 to IFC4 classifications
  • Fix broken export when object names are too long
  • Fix bug where importing mapped type representations may accidentally reuse other meshes
  • More lenient parsing to skip invalid representations and not stop halfway (as discovered in ArchiCAD-produced files)
