hello very good questions. i dont know why the changes in guid happen...it is very cumbersome for me too. i think this might be somehow connected with the fact that other applications write ifcs differently...but i am not sure. i have noticed that when an ifc is loaded into navisworks a sharedparameter file is created too. why i dont know?...is it for revit? why is this so? regards
Hi as far as i know try this procedure here... https://forums.buildingsmart.org/t/how-to-link-files-external-information-like-pdf-documents-to-an-ifc-file/1452 what you could do is write the shared parameter to a custom parameter in ifc with the data type text ...but after exporting there is no real hyperlink in the ifc... only text....it is explained here... https://revitiq.com/creating-custom-ifc-property-sets/
Hi An Feh I think you could do the following: Try to create separate IFCs using different 3D Views. Try to export the different buildings using different 3D Views. Try to use Worksets on the different Buildings as well. Don’t exaggerate the use of worksets but it may help. You could do the following too: Copy the Revit file and delete all the geometry. Yes, all of it. But please leave the levels. Place a 3D annotation on every story level. I mean we know that only story levels are important for ifc....
Hello Everyone and merry Christmas! I am experiencing the same problems. I tried Peters Dynamo and the issue was still ongoing. The dynamo runs well, but the empty Parameters are still visible in the IFC file. I use 2x3. My thoughts on the topic: I think that Revit in IFC matters, has troubles assigning attributes. Specially using Projectparameters and Family parameters. When shared parameters come into play, lets say in a family and as a Projectparameter and of course as shared parameter, things...
Good workaround carolino...it helped me as well...
Hi Phil.... Well lets say not every wall is the same wall...with walltype you can typify deeper using IFC Standards....you have to check wich wall type in revit suits the ifc type....for that use IfcExportAs... you will see ifcwalltypes on the enum link.... https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/FINAL/HTML/ifcsharedbldgelements/lexical/ifcwalltypeenum.htm https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD2_TC1/HTML/schema/ifcsharedbldgelements/lexical/ifcwalltypeenum.htm

Well the door has to be entirely placed in the wall .... it affects of course the height and the offsets if you use them....look this is the parameter ...sorry they are in german i could start revit in english i will ...
