I want to generate the su model by ruby and save the ifc information at the same time. That’s my code: #1. create a group by l, b, h and transform group to component l = 5000 b = 600 h = 800 model = Sketchup.active_model entities = model.active_entities status = entities.clear! #clear the…

Have a look at the IFC exporter on github: [image] Releases · BIM-Tools/SketchUp-IFC-Manager IFC data manager and exporter for SketchUp. Contribute to BIM-Tools/SketchUp-IFC-Manager development by creating an account on GitHub.

Thanks for your reply. I try to understand that plugin’s code.

The solution: # 1. create a group by l, b, h and transform group to component l = 5000 b = 600 h = 800 model = Sketchup.active_model entities = model.active_entities status = entities.clear! #clear the entities!!! group = entities.add_group pts = [] pts[0] = [0, 0, 0] pts[1] = [l, 0, 0] pts…

Please note that if you do not use the IFC Manager extension, the IFC export does not fully meet the “requirements” of buildingSMART.

Thanks for attention. In the IFC Manager extension, I think \bt_ifcmanager\lib\lib_ifc\IfcRelDefinesByProperties_su.rb is the key file. I post the code from line 43 to line 107: if sketchup.is_a?( Sketchup::AttributeDictionary ) attr_dict = sketchup if attr_dict.name == "BaseQuanti…

The reply of SketchUp IFC manager plugin’s author: At the moment there are two supported methods for writing properties. Add AttributeDictionaries under the “IFC 2x3” dictionary. So they are part of the IFC data. Like when you import an IFC containing additional property sets. Add AttributeDictio…

The IFC data set uses nested attribute dictionaries. "Width", "Height", "Depth" are not attribute keys, they are nested dictionary names, and their values are in stored in the key named "Value". The IFC data may also be assigned to the definition and not the instance. Try something like this … d…

It’s so kind of you! Is my understanding correct? I think there is a dictionary named “'IFC 2x3”, and the “IFC 2x3” dictionary has a dictionary named “BaseQuantities”. Then the “BaseQuantities” dictionary has the dictionary named “Width”, “Depth”, “Height”. Each of “Width”, “Depth”, “Height” has…

This causes major import problems, because each element has to be unique, regardless if it is the same ‘geometry’ or representation of.

That would seriously reduce the amount of simular components were the only difference is the name…
