4 years ago Changing the IfcProprties dict does work, yes. The thing is, ATM you cannot change any of the members of a property directly. You can only replace the property as a whole. ie; this doesn't work:
myobj.IfcProperties["Length"] = 60
but this works:
d = myobj.IfcProperties
d["Length"] = 60
myobj.IfcProperties = dThe IfcProperties dict works a bit specifically, though, I suppose you saw that already, you must write key:value pairs like this:
"PropertyName;;PropertySet":"PropertyType;;Value"
example:
"Description;;WallCommon":"IfcText;;My description text"
Hope this helps!

Note the "Default property set" string.
Hi,
first of all, this is a very cool project. I was wondering whether there is a way to programmatically edit IFC properties of components? Changing the
IfcPropertiesdict does not have any effect. I also could not find any place in the code where they would be assigned.Maybe this is an XY problem? We want to have a FreeCAD model whose properties (like width, length, ...) can be changed with a python script. Currently this is done with a spreadsheet whose cell values are linked to the geometry. Now exporting this model to IFC works, but we additionally want to persist the "dynamic" properties as IFC properties.
My vision would be to simply set some
IfcPropertiesafter setting the spreadsheet values in the python script. Is there another (perhaps more canonical) way?
