Verified usage

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

Model

✓ import lib3mf

✗ from lib3mf import Model

Model is a class within the lib3mf module; direct import may fail because the module's __init__.py often doesn't expose submodules directly. Use 'import lib3mf' and then 'lib3mf.Model'.

Prints the version of the underlying lib3mf C++ library and creates a new empty model.

import lib3mf wrapper = lib3mf.getLibraryVersion() print('Version', wrapper.getMajor(), wrapper.getMinor(), wrapper.getMicro(), wrapper.getBuild()) model = lib3mf.Model() print('Model created')

Debug

Known issues

breakingVersion 2.x uses a completely different API from 1.x. The old functions (e.g., 'createModel', 'loadModel') are removed. You must rewrite code using the new object-oriented API.

fix

Refer to official documentation for the 2.x API. Use 'lib3mf.Model()' instead of 'createModel()'.

affects: >=2.0.0

gotchaThe Python package only provides bindings; the actual 3MF library must be installed separately or bundled. On some systems, `pip install lib3mf` may not work without a preinstalled 3MF SDK.

fix

Ensure the lib3mf C library is installed (e.g., via system package manager) or use the official binary wheels if available.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'lib3mf'

lib3mf not installed or pip install failed silently due to missing C library.

fix

Install with pip: 'pip install lib3mf'. If that fails, install the 3MF SDK first (see lib3mf.org).

ImportError: cannot import name 'Model' from 'lib3mf'

Attempting to import Model as a top-level attribute, but it is nested within the module.

fix

Use 'import lib3mf' and then 'lib3mf.Model'.
