python-mvdxml

A mvdXML checker and w3c SPARQL converter, as an IfcOpenShell submodule or stand-alone.

WARNING: While this repository has many useful building blocks to build software around mvdXML and IFC, there are many mvdXML dialects and not all variants are likely to be fully supported.

Quickstart

Extraction

importifcopenshellfromifcopenshell.mvdimportmvdmvd_concept=mvd.open_mvd("examples/wall_extraction.mvdxml")
file=ifcopenshell.open("Duplex_A_20110505.ifc")
all_data=mvd.get_data(mvd_concept, file, spreadsheet_export=True)
non_respecting_entities=mvd.get_non_respecting_entities(file, all_data[1])
respecting_entities=mvd.get_respecting_entities(file, all_data[1])

# Create a new filenew_file=ifcopenshell.file(schema=file.schema)
proj=file.by_type("IfcProject")[0]
new_file.add(proj)
foreinrespecting_entities:
