Thanks for reporting. Can you share the mvdXML file? There are quite a bit of versions of the schema floating around. Would help us investigate.
Thanks for the reply! I saved it in ifcdoc in mvdxml version 1.1(the official version) Using different Ifc files I get similar exceptions for different attributes. IfcBuilding.txt
This file is actually a mvdxml file. I changed it to txt, so I can upload it.
With the recent commits you can get the expected results using the snippet below on the model here in IFC4 at http://openifcmodel.cs.auckland.ac.nz/Model/Details/307 :
import ifcopenshell
from ifcopenshell.mvd import mvd
concept_roots = list(ifcopenshell.mvd.concept_root.parse(r"examples/building.mvdxml"))
file = ifcopenshell.open(r"models\20160125Autodesk_Hospital_Parking Garage_2015 - IFC4.ifc")
for concept_root in concept_roots:
print("ConceptRoot: ", concept_root.entity)
example_entity = file.by_type(concept_root.entity)[0]
concepts = sorted(concept_root.concepts(), key=mvd.is_applicability, reverse=True)
for concept in concepts:
print("Concept Name: ", concept.name)
# print(concept.template().rules)
if len(concept.template().rules) > 1:
attribute_rules = []
for rule in concept.template().rules:
attribute_rules.append(rule)
rules_root = ifcopenshell.mvd.rule("EntityRule", concept_root.entity, attribute_rules)
else:
rules_root = concept.template().rules[0]
data = mvd.extract_data(rules_root, example_entity)
print("Result from traversal:")
for d in data:
for k,v in d.items():
print(k,v)
print()
print("\n")
Output:

Thanks alot Johan. It is working. I can produce the same result as you have.
I have a confusion still. How can I use mvd to create the result ifc file? I see the data
variable from above being a list of concepts and using extract_data
and there is also the example from readme
file with get_data() method.
I am not sure how I can follow up!
Thanks

With a MVD containing IfcBuilding with concept template 'revision control' , I am getting this exception:
