Zone relations

B by BalThorsGate on 17 Dec 2022, edited 19 Dec 2022 #

Hello fellow nerds.

I am fairly new to python and ifcopenshell.

And i wonder, is it possible to get to an element based on what sone it relates to?

Like a bathroom connected to a wall and then a hallway on the other side.

As long as the geometry is cut accordingly i should work, right?

And if it does, perhaps someone could point me in the direction of an answer?

Thank you :)

I think topologic does what you are asking for,

I'm also a newbie, but something like the following might work.

I also attached a blenderbim/ifc file, if you'd like to play around with it as well.


import bpy

import ifcopenshell

from blenderbim.bim.ifc import IfcStore




Ifc = ifcopenshell.open(IfcStore.path)

first_zone = Ifc.by_type("IfcZone")[0]

listofwalls = []

first_zone_is_groupedby = first_zone.IsGroupedBy

for group in first_zone_is_groupedby:

    spatialobjects = group.RelatedObjects

    for spatialobject in spatialobjects:

        spatialstructures = spatialobject.ContainsElements

        for spatialstructure in spatialstructures:

            elements = spatialstructure.RelatedElements

            for element in elements:

                if element.is_a("IfcWall"):

                    listofwalls.append(element)


for entity in listofwalls:

    wallname = "IfcWall/" + entity.Name

    obj = bpy.data.objects[wallname]

    obj.select_set(True)
