Installation

Requirements

• Python 3.10+
• A working C++ compiler is not required --- llmcad uses pre-built OpenCASCADE bindings.

Install with pip

pip install llmcad

This installs llmcad and its dependencies:

Package	Purpose
cadquery-ocp	OpenCASCADE (OCCT) Python bindings
numpy	Numeric operations
Pillow	Image handling for snapshots
vtk	Offscreen rendering for snapshot()

Install with conda

If you're using conda/miniconda:

pip install llmcad

Note

Even with conda, pip install is the recommended method. The cadquery-ocp dependency provides pre-built wheels for all major platforms.

Verify installation

import llmcad
print(llmcad.__version__)

from llmcad import Box, snapshot
box = Box(10, 20, 30)
snapshot(box, "test_box")
# Should create test_box.png in the current directory

Development install

To install from source for development:

git clone https://github.com/llmcad/llmcad.git
cd llmcad
pip install -e ".[docs]"

Building the docs

pip install mkdocs-material
mkdocs serve

Then open http://localhost:8000 in your browser.
