alibrex 1.0.0

Typed Python bindings for the Alibre Design V29 AlibreX API

alibrex package

alibrex is a Python wrapper for the Alibre Design V29+ AlibreX automation API. The native AlibreX is a COM interface exposed to .NET alibrex turns it into a typed, idiomatic Python module.

Features

• Full IDE support. Every interface, enum, and method is declared in PEP 561 type stubs — autocomplete, hover docs, and type-checking work out of the box in VS Code, PyCharm, or any pyright/Pylance-aware editor.
• Single namespace. Everything is at the top level: CurrentPart(), CurrentAssembly(), connect(), plus ~280 typed AlibreX interfaces and enums.
• Example and demo driven. The repository includes Jupyter notebooks, plus dozens of test scripts, demos and reference utilities.

examples/ported/library/	Standalone utilities (gear generator, STL exporter, equation sketcher, etc.)
examples/probes/	Property-probe reports for the major object types
examples/pdm/	PDM (Product Data Management) walk-through — 13 progressive scripts: connect → safes → property defs / classes / templates → projects / libraries / folder tree → file properties + version history → locked-file scan, session ↔ PDM cross-ref, full Program.cs port
examples/_sample_files/	Sample .AD_PRT / .AD_ASM materialized on first use by file-loading examples

Requirements

• Windows + a licensed installation of Alibre Design (V29 or newer)
• Old versions of Alibre Design may work, but are not tested
• Python 3.9–3.13
• pythonnet>=3.0,<4 (installed automatically)

AlibreX.dll is not redistributed at import time alibrex locates it by checking, in order, the $ALIBREX_DLL env var, the Windows registry (AlibreX.AutomationHook COM ProgID, then HKLM\SOFTWARE\Alibre, Inc.\Alibre Design\…\HomeDirectory), and finally a %ProgramFiles%\Alibre Design*\Program\AlibreX.dll

see notebooks/diagnose_setup.ipynb to inspect what each source returns on your machine.

Quick start

Open Alibre Design and any part document, then:

from alibrex import CurrentPart

part = CurrentPart()
print(part.Name, part.FeatureCount, part.Bodies.Count)

See notebooks/00_hello.ipynb and notebooks/connect_methods.ipynb to get oriented.
