LPub3D

LPub3D is an open-source WYSIWYG editing application for creating digital building instructions in a LEGO-style format. It gives users a visual environment for working with instruction content. The application is intended for people who need to turn digital brick models into organized building instructions.

LPub3D uses the LDraw parts library as its source of digital brick components. It reads LDraw LDR and MPD model file formats, allowing those models to serve as input. Its editing workflow focuses on arranging and presenting model-building steps as instructions. The software is released under the GNU General Public License version 3.

As a graphics-design application, LPub3D fits tools used to visually prepare material from digital models. It is relevant to users working with LDraw-based LEGO-style designs and instruction documents. The Linux version is intended for creating or editing this material on Linux systems.

MirrorNest distributes the official LPub3D build directly from its own storage. MirrorNest scans the build for malware before publishing it. This setup provides a Linux download through the catalog while keeping the distributed software tied to the official build.
