Basics.1 Project Overview

This example shows how to load an IFC file and print a summary of the model.

from compas_ifc.model import Model

model = Model("data/wall-with-opening-and-window.ifc")
model.print_summary()

================================================================================
File: data/wall-with-opening-and-window.ifc
Size: 0.01 MB
Project: Default Project
Description: Description of Default Project
Number of sites: 1
Number of buildings: 1
Number of building elements: 2
================================================================================

from pprint import pprint
from compas_ifc.model import Model

model = Model("data/wall-with-opening-and-window.ifc")

project = model.project

# =============================================================================
# Info
# =============================================================================

print("\n" + "*" * 53)
print("Project")
print("*" * 53 + "\n")

project.print_inheritance()

print("\nAttributes")
print("=" * 53 + "\n")

pprint(project.attributes)

print("\nProperties")
print("=" * 53 + "\n")

pprint(project.properties)

print("\nRepresentation Contexts")
print("=" * 53 + "\n")

pprint(project.contexts)

print("\nUnits")
print("=" * 53 + "\n")

pprint(project.units)

print("\nModel Context")
print("=" * 53 + "\n")

print(f"Reference Frame: {project.frame}")
print(f"True North: {project.north}")

print("\nSites")
print("=" * 53 + "\n")

print(project.sites)

print()
