Jsou aktualizovány moduly IFC rozšíření pro Revit 2016 a 2017 - viz Download, resp. Autodesk Apps. Přehled změn a novinek: 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.
