"Update Representation" after an applied Boolean modifier?

1. B by BIMrookie92 on 13 Jan 2023, edited 13 Jan 2023 #

   Hi,

   I am trying to "cut" objects using a boolean modifier, apply that modifier, and update the resulting mesh by clicking the "Update Representation" button on the object in Blender. I get the following error. Does anyone have any idea what I should do? If I alter the object by eg. deleting vertices instead, the update doesnt throw this error..

   Python: Traceback (most recent call last):

   File "C:\Users\sbe\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\addons\blenderbim\bim\module\geometry\operator.py", line 138, in execute

   return IfcStore.execute_ifc_operator(self, context)

   File "C:\Users\sbe\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\addons\blenderbim\bim\ifc.py", line 369, in execute_ifc_operator

   result = getattr(operator, "_execute")(context)

   File "C:\Users\sbe\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\addons\blenderbim\bim\module\geometry\operator.py", line 153, in _execute

   style = self.settings["styles"].pop(0)

   Hello ! This might be better suited for an issue on the github tracker : https://github.com/IfcOpenShell/IfcOpenShell/issues I think if you want to use boolean operations, you must not use the regular boolean modifier, you have to create an IfcBoolean and add it as a Boolean operation to your object, otherwise it won't be register as a boolean operation. Or you can (I think ?) use a tesselation representation, but this will be desctructive. Before you clicked on "Update Representation", what was the representation of your object ?
