sh3dkit

sh3dkit is a flexible and extensible Python library and command-line interface (CLI) toolset for working with .sh3d files, commonly used by Sweet Home 3D. It provides an easy way to render, visualize, and convert .sh3d files into other formats such as SVG, while offering an architecture to add support for additional renderers in the future.

Key Features:

• Render .sh3d files: Extracts and visualizes floor plans and 3D home designs from .sh3d files.
• Format Conversion: Convert .sh3d files into various output formats, including SVG, and with the potential for more formats in the future.
• Extensible: Built with flexibility in mind, allowing for easy addition of new rendering engines (e.g., Matplotlib, custom formats).
• CLI and Library: Provides both a command-line interface (CLI) and a Python library for use in automated workflows or custom applications.
• Easy Integration: Installable via pip and ready to use in your Python projects.

Whether you're an architect, a designer, or a developer working with home design data, sh3dkit enables efficient processing of Sweet Home 3D project files for your own needs.

CLI

Currently only convertion into SVG is supported by using sh3d2svg command provided in sh3dkit/bin/sh3d2svg.py, it usage is:

Usage: sh3d2svg [OPTIONS] INPUT_FILE

Options:
  -o, --output TEXT      Output SVG file path.
  -l, --level-name TEXT  What level name to render, if not specified all are
                         rendered into separate files automatically.
  --help                 Show this message and exit.

API

Single renderer interface is provided for implementation in sh3dkit/renderer/HomeRenderer.py, SVG renderer used by sh3d2svg command is implemented in sh3dkit/renderer/SvgHomeRenderer.py. "Only" these functions are required to be implemented to get your custom renderer working:
