LPub3D

LPub3D is an open source editor designed for creating digital building instructions compatible with the LDraw standard. Users can import existing models, structure multi-step building sequences, and generate printable or viewable documentation detailing how physical brick sets are assembled. The application provides tools for camera angle adjustments, part list generation, and page layout organization.

The software runs on Linux operating systems and relies on the LDraw parts library to render individual components. It processes data files to produce visual steps, helping users compile structural guides from computer-aided design files without requiring proprietary publishing suites. Output formats generally target standard document viewers and printers for physical assembly reference.
