LPub3D Win64

LPub3D Win64 is the 64-bit Windows edition of LPub3D, an open-source application by Trevor SANDY for creating professional, step-by-step building instructions for digital LEGO models. Built on the LDraw ecosystem, it opens .ldr and .mpd files, manages submodels and steps, and gives you precise control over page layout, styles, and annotations to produce publication-ready instructions.

Key features:

• High-quality step rendering using LDraw-compatible renderers
• Automatic Parts List per step (PLI) and project-wide Bill of Materials (BOM), with sorting, grouping, and part counts
• Callouts, multi-step assemblies, rotation arrows, and fade/ghosting to highlight changes between steps
• Flexible page design: headers/footers, page numbers, margins, backgrounds, templates, and common paper sizes
• Export to PDF and raster images (such as PNG and JPG) for printing and sharing
• Native 64-bit performance for handling large and complex models
• Interactive 3D preview and camera controls to fine-tune views and orientations
• Tools for managing submodels, references, and part color consistency

LPub3D Win64 is free and open source, making it a strong choice for hobbyists, MOC designers, educators, and anyone who wants clear, professional LEGO-style instructions on 64-bit Windows systems. It requires the LDraw parts library and a compatible renderer.
