I have some issues with exporting and importing IFC files.
FreeCAD Version: 0.18.4, Win 10
I modeled a simple house with, I think, no complex structure.
I downloaded the latest version of IfcOpenShell (https://github.com/IfcOpenShell/IfcOpenShell
, master branch) and followed the installation instructions of the FreeCAD wiki. An error message was not displayed.
But every time I try to export an IFC file, I get the following error:
I'm not an IFC expert but I assume that meas the wrong IFC version is used?
According to the Preflight Checks - Tool the IFC4 support is not enabled but all my Psets are IFC4 Add2, so maybe this causes the error?
But I have no clue where to change the used IFC version...According to the wiki entry of FreeCAD (https://www.freecadweb.org/wiki/Arch_IFC
), the used IFC version (2x3 or 4) should be visible in the Arch preferences, but I can't find anything there regarding IFC.
The other problem is, I tried to import some really easy IFC files exported from Revit but every time FreeCAD crashes. I also tried to open this IFC file I found on another Forum post (https://forum.freecadweb.org/viewtopic.php?f=39&t=36754
file: http://ifcopenshell.org/ifcopenhouse/v4 ... nHouse.ifc
But it's not working. But it is IFC 2x3 which is most likely set.
So did I do something wrong with the IfcOpenShell installation?
I would be very grateful if someone could help me out!
