Merge elements with same GUID or TAG

ZanoniZanoni
in General

It's possible to merge elements with the same GUID or TAG?

I tried using Patch Merge Duplicate Types (https://blenderbim.org/docs-python/autoapi/ifcpatch/recipes/MergeDuplicateTypes/index.html) but when I open my ifc file in BIMcollab exists more than 1 element with the same TAG.

    Do you have some example file? Your code should merge them fine, see the example below.

    import ifcopenshell
import ifcpatch
ifc_file = ifcopenshell.file()

guid = ifcopenshell.guid.new()

# merge by global id
ifc_file.createIfcWallType(GlobalId=guid)
ifc_file.createIfcWallType(GlobalId=guid)
ifc_file.createIfcWallType(GlobalId=guid)
print(len(ifc_file.by_type("IfcWallType"))) # 2
ifcpatch.execute({"input": None, "file": ifc_file, "recipe": "MergeDuplicateTypes", "arguments": ["GlobalId"]})
print(len(ifc_file.by_type("IfcWallType"))) # 1

# merge by tag
tag = "test tag"
ifc_file.createIfcBeamType(Tag=tag)
ifc_file.createIfcBeamType(Tag=tag)
print(len(ifc_file.by_type("IfcBeamType"))) # 2
ifcpatch.execute({"input": None, "file": ifc_file, "recipe": "MergeDuplicateTypes", "arguments": []})
print(len(ifc_file.by_type("IfcBeamType"))) # 1

    Here is an example. I zipped the file so I could upload it.

    Some elements with the same GUID:

    1E1yvzyVb0LAZDdant$cp5
    1E1yvzyVb0LAZDdant$cp6
    1E1yvzyVb0LAZDdant$cpH
    1E1yvzyVb0LAZDdant$cpi
    1E1yvzyVb0LAZDdant$cpj
    1E1yvzyVb0LAZDdant$cpm
    1E1yvzyVb0LAZDdant$cpn
    1E1yvzyVb0LAZDdant$cpo
    1E1yvzyVb0LAZDdant$cpp
    1E1yvzyVb0LAZDdant$cpR
    1E1yvzyVb0LAZDdant$cpz

    1E1yvzyVb0LAZDdant$cpz

    These are all different GUIDs.

  • ZanoniZanoni

    @brunopostle In each guid informed there are 4 elements...

    1E1yvzyVb0LAZDdant$cp5 - There are 4 elements
    1E1yvzyVb0LAZDdant$cp6 – There are 4 elements

    All those guids are not types but occurrences, MergeDuplicateTypes merges only types. Though it does merge types of those elements if they have matching guids - e.g. 3694759, 3480919, 2388844, 359263 (guid 1E1yvzyVb0LAZDdant$cpj) IfcWallStandardCases are pointing to different types with the same guid 0utCMpdeTCJOHnXCC6IWFD and all those types are merged by ifcpatch.

    import ifcopenshell
import ifcpatch

filepath = r"duplicates - Copy.ifc"
ifc_file = ifcopenshell.open(filepath)

def get_elements_by_guid(guids):
    elements_by_guid = dict()
    for element in ifc_file:
        guid = getattr(element, "GlobalId", None)
        if guid in guids:
            elements_by_guid.setdefault(guid, list()).append(element)
    return elements_by_guid

for guid, elements in get_elements_by_guid(guids).items():
    print(f"Found elements by {guid}: {len(elements)}")
    for elem in elements:
        print(f"\t{elem}")
