Extract certain elements into a new model

Extract a subset of elements from an existing IFC data set and save it to a new IFC file. For example, you might want to extract only the walls in a model and save it as a new model.

Parameters:

query (str) – A query to select the subset of IFC elements.

Example:

# Extract all walls
ifcpatch.execute({"input": "input.ifc", "file": model, "recipe": "ExtractElements", "arguments": ["IfcWall"]})

# Extract all slabs
ifcpatch.execute({"input": "input.ifc", "file": model, "recipe": "ExtractElements", "arguments": ["IfcSlab"]})

# Extract all walls and slabs
ifcpatch.execute({"input": "input.ifc", "file": model, "recipe": "ExtractElements", "arguments": ["IfcWall, IfcSlab"]})
