COMPAS is an open-source, Python-based framework for computational design and digital fabrication. It provides data structures, algorithms, and utilities for geometry processing, topology optimization, and robotic assembly. Current version 2.15.1 supports Python >=3.9, with a stable release cadence.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Box

✓ from compas.geometry import Box

✗ from compas.datastructures import Box

Box is a geometry primitive, not a datastructure.

Network

✓ from compas.datastructures import Network

✗ from compas import Network

Network is in compas.datastructures.

trimesh_remesh

✓ from compas.geometry import trimesh_remesh

✗ from compas.topology import trimesh_remesh

Function moved to compas.geometry in recent versions.

Creates a 3D box and visualizes it using COMPAS View2.

from compas.geometry import Box from compas_view2.app import App box = Box(1, 2, 3) viewer = App() viewer.add(box) viewer.show()

Debug

Known issues

gotchaCOMPAS depends on a C++ backend (compas_cgal) for some geometry operations; must be installed separately.

fix

pip install compas_cgal

affects: >=2.0

deprecatedThe compas_rhino package is deprecated and replaced by compas_view2 for Rhino integration.

fix

Use compas_view2 instead.

affects: >=2.13

gotchaIn version 2.x, many geometry functions moved from compas.topology to compas.geometry. Old imports may still work but raise deprecation warnings.

fix

Update imports to compas.geometry.

affects: >=2.0

breakingThe Point class attribute names changed: 'x','y','z' are now 'xy','yz','zx' for coordinate arrays.

fix

Access coordinates via .x, .y, .z (not .xy).

affects: >=2.15

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'compas_view2'

Missing optional viewer package.

fix

pip install compas_view2

ImportError: cannot import name 'Box' from 'compas.datastructures'

Incorrect import path for Box.

fix

from compas.geometry import Box

AttributeError: 'Box' object has no attribute 'xy'

Outdated attribute access pattern.

fix

Use box.x, box.y, box.z instead of box.xy.
