Autodesk IFC 2017 Add-in Version Released

From the Autodesk App Store...

About This Version

Version, 8/23/2016
  • General:
    • Finished French localization.
  • New Export Functionality:
    • Use "Reference Level" as the base level of the element when exporting certain MEP components.
    • Support export of mass density units.
  • Export Bug Fixes:
    • Export rooms and areas even if they have improperly closed internal boundaries.  Note that the IfcSpace created may then be missing expected interior holes.
    • Fix error when exporting some 0 height walls when they have associated parts.
    • Only associate a door or window with one opening, even if the door or window is inserted into multiple walls, as per the IFC standard.
  • New Import Functionality:
    • Add an API option that allows for always reading in bounding box information, even if the entity has a Body representation.
    • Allow reading in curve information that's not contained in the Axis representation, to allow for wireframe import.
    • Map IfcOutletType and IfcProtectiveDeviceType to Electrical Fixtures and Specialty Equipment, respectively.
    • Improved support for IFC2x and IFC2x2 files.
    • Support proper scaling of mass density units.
  • Import Bug Fixes:
    • Don't complain about missing IfcOwnerHistory for IFC4 files.
    • Properly scale metric bounding boxes so that they are the correct size.
    • Stop ignoring some IfcGroups (and IfcSystems) that weren't included in the structure as Revit previously expected.
