P_BOUNDEDVALUE: how to set the range to a custom PSET property?

mastrolube

Hi there!
I wanted to use a range for a value so I've set P_BOUNDEDVALUE in PSET template.
When I add this custom PSET to my object the propeties are missing.
Am I doing something wrong?
Thank you very much!

It's a known issue https://github.com/IfcOpenShell/IfcOpenShell/issues/4047

@Moult I made a script to set these values.

import bonsai.tool as tool 
import ifcopenshell
import ifcopenshell.guid
import logging
import sys

logger = logging.getLogger("Pset_mod") 
logger.setLevel(logging.DEBUG) 
stream_handler = logging.StreamHandler(sys.stdout)
stream_handler.setFormatter(logging.Formatter("%(asctime)s - %(levelname)s - %(message)s"))
logger.addHandler(stream_handler) 

ifc_file = tool.Ifc.get() 
if not ifc_file:
    raise Exception("IFC file not loaded.")

elements = ifc_file.by_type("IfcWall")

for element in elements:
    existing_pset = None
    for rel in element.IsDefinedBy:
        if rel.is_a("IfcRelDefinesByProperties") and rel.RelatingPropertyDefinition.is_a("IfcPropertySet"):
            if rel.RelatingPropertyDefinition.Name == "DIA_design":
                existing_pset = rel.RelatingPropertyDefinition
                break

    owner_history = None
    if ifc_file.by_type('IfcOwnerHistory'):
        owner_history = ifc_file.by_type('IfcOwnerHistory')[0]

    if not existing_pset:
        existing_pset = ifc_file.createIfcPropertySet(
            ifcopenshell.guid.new(),
            owner_history,
            'DIA_design',
            None,
            []
        )
        ifc_file.createIfcRelDefinesByProperties(
            ifcopenshell.guid.new(),
            owner_history,
            None,
            None,
            [element],
            existing_pset
        )

    ac_ratio = ifc_file.createIfcPropertyBoundedValue(
        'A/C',
        None,
        ifc_file.createIfcRatioMeasure(1),  # Upper bound
        ifc_file.createIfcRatioMeasure(0.9),  # Lower bound
        ifc_file.createIfcRatioMeasure(0.95),  # Nominal value
        None
    )

    peso_specifico = ifc_file.createIfcPropertyBoundedValue(
        'Peso_specifico',
        None,
        ifc_file.createIfcMassDensityMeasure(1650),  # Upper bound
        ifc_file.createIfcMassDensityMeasure(1450),  # Lower bound
        ifc_file.createIfcMassDensityMeasure(1550),  # Nominal value
        None
    )

    viscosita = ifc_file.createIfcPropertyBoundedValue(
        'Viscosità',
        None,
        ifc_file.createIfcTimeMeasure(50),  # Upper bound
        ifc_file.createIfcTimeMeasure(47),  # Lower bound
        ifc_file.createIfcTimeMeasure(48),  # Nominal value
        None
    )

    new_properties = []
    for prop in existing_pset.HasProperties:
        if prop.Name not in ['A/C', 'Peso_specifico', 'Viscosità']:
            new_properties.append(prop)

    new_properties.extend([ac_ratio, peso_specifico, viscosita])
    existing_pset.HasProperties = tuple(new_properties)

logger.info("Done.")

This is what it looks like on blender

And in BimVision I get exatcly what I was looking for:

( I don't know why it shows kg/m² instad of kg/m³ but it must be a bug of BimVision)

Uhm I tried to validate from buildingSMART and it looks bad :S
