hello, i cannot find a solution at one point, while inspecting ifc-parameters. i use in 2x3: path = [my_scheme, my_element, Description, IfcText] local_value = my_definition.get_classification_value(path) good so far, but here i have to know , that an attribute named “Description” is included (…

This has been discussed before … [image] Get all Bim informations of a componant! We don’t have any special API methods to traverse all the classification data, but you can traverse the nested set of attribute dictionaries yourself using the AttributeDictionary iterators.

hi dan, but how can i traverse thru when a path is necessary with a “NAME” , i want to find out and do not know? at the moment i have a set (array) of known "names " (like “longname”) and iterate with the path to find out , if they exist in the instance. but which is the name of the attribute dir…

Install one of the Attribute Inspector extensions and do some investigative homework.

yes, i will. maybe a last question :slight_smile: is an user created dynamic attribute dictionary the equivalent to a pset ? ( just to understand, how i can create a new special pset for a ifcdoor-element … thanx for helping . stan

I don’t know what a pset is, but if it is something like Ruby’s PStore or a JSON file, then yes. The name “attribute dictionary” comes from the C++ programming language. It is a data list of key/value pairs. Each key/value pair is a data attribute. Just like a language dictionary, attributes are …

There’s no such thing as a universal Propertyset, some software might have that implemented as default name, but it’s usually ‘category’ dependent and as such, names like Pset_curtain_wall (followed with an underscore and specific name) can occur and be used.

hi, thanx a lot! what i am trying to understand: if a ifc-file also has some pset definitions in to ( as Pset_curtain_wall ), is this than a separate attribute dictionary in the ifc-dictionary? thanx stan

They won’t import in SketchUp desktop app….

i mike, i see. i am starting with ifc, so if i may ask: if a cad-3d-software has the option to create a pset, is this pset, when ifc is exported a separate file belonging to the ifc-model? or do i have to create a pset with a text-editor or so ? thanx stan

It truly depends on which software. Usually, there is an exporter, a software specific module responsible for what to export and, even more important, how to map those attributes to the Building Smart standard (IFC 2x3 or IFC 2x4). Revit has it’s own exporter, so does Archicad and SketchUp. They’…
