I send another revit file, ifc file and custom parameter mapping file (Exported with 18.4.0 version). In the IFC file you can see that common property sets as Pset_SlabCommon is duplicated. This did not happen in former versions of the IFCExporter. This is quite annoying because some ifcviewers like navisworks show all this duplicated propertysets when you select an element.

I send Revit 18 file, Custom PropertySets mapping file, and IfcFile. You can see how slabs and walls have double CommonPropertySets, and double Custom PropertySets.

With the last version of IFCExporter (18.4.0) Custom property sets are duplicated and also CommonPropertySets. How can I solve It to not happen? Thanks

When you export A structural beam sistem to IFC it exports all the beams as a Assembly class and with Beam_GRID as Predefined Type. This is nice. When you export a Truss it exports all the Truss as an Assembly class (this is fine and correct) and exports the cords as IfcBeams and the rest (diagonals) as IfcMembers. I think cords should be also exported as IfcMembers. It would be nice if this is included in the code because using IfcExportAs parameter I need to create to types (if the same beam acts...

Seems like Revit when it comes to link a IFC uses the internal origin as (0,0,0). So if I have a IFC with real coordinates it does not "go" to the correct place, because if configure the site properties of the revit files indicating that the "internal origin" has coordinates (10,10,10), and I insert an IFC link with an object at coordinates (0,0,0) Revit send it to the internal origin so it is 10 units shifted. which is the correct way to link an IFC file so it is located in his real position? Thanks...

Dirk, it looks like CommonPropertySets of Project and Site are not suported by the IFC Exporter. I only manage to get commonpropertysets from IFCbuilding to the rest of building elements. Would be nice if IFC Exporter also suports Project and Site common propertysets. Miquel

Ok Dirk, I did not think about this method, but it's evident that this is the one that give us more guarantee to not have an error. Thanks Miquel

To edit the shared parameter file, any recomendation to create a new GUID for the parameter?. For example to copy the original one, and just change the last number? Miquel
