Third Party Software
developed by Allen Smith allows you to create virtual instructions for your Lego creations on your Mac.
LDCad, developed by Roland Melkert, is a multiplatform LDraw editor that lets you edit LDraw model documents in real-time. LDCad is part of the AIOI - LDraw All-In-One-Installer.
LeoCAD, developed by Leonardo Zide, is a CAD program for creating virtual LEGO models. LeoCAD is part of the AIOI - LDraw All-In-One-Installer.
also known as Mike's LEGO CAD, is a LDraw CAD program developed by Michael Lachmann, which has the ability to create and manage Multi-Part Document files. You can create models with it and add steps to create instructions. MLCad is part of the AIOI - LDraw All-In-One-Installer.
LDView, developed by Travis Cobbs, is a real-time 3D viewer for displaying LDraw models using hardware-accellerated 3D graphics. LDView is part of the AIOI - LDraw All-In-One-Installer.
LPub3D, developed by Trevor Sandy, is a WYSIWYG editing application for creating LEGO style digital building instructions. Portions of LPub3D are based on LPUB© 2007-2009 Kevin Clague, LeoCAD© 2015 Leonardo Zide and additional third party components. LPub3D is part of the AIOI - LDraw All-In-One-Installer.
LIC - LEGO Instruction Creator, developed by Jeremy Czajkowski, is a cross-platform, Python, OpenGL & Qt powered desktop application for creating and editing LEGO instruction books. LIC imports 3D models, organizes them into submodels, pages & steps, and exports the end result as images or PDF. A rich, WYSIWYG UI editor, which provides a fully interactive preview window along side a drag & drop-enabled navigation tree, to help organize and layout your book. Portions of LIC are based on work of Remi Gagne. LIC will be part of the AIOI - LDraw All-In-One-Installer.
LDConfig Manager, developed by Michael Heidemann, should allow you to maintain the LDConfig.ldr file by a GUI.
LDFind, developed by Michael Heidemann, should enable you to quick find the part you are searching for. LDFind is part of the AIOI - LDraw All-In-One-Installer.
LSculpt, developed by Bram Lambrecht, is a program which converts a triangle mesh into an LDraw file. The generated model consists of a surface of 1×1 plates oriented in whichever direction provides the best detail. LSculpt is part of the AIOI - LDraw All-In-One-Installer.
LSynth, developed by Don Heyse, is a program that synthesizes bendable parts for LDraw files. LSynth is part of the AIOI - LDraw All-In-One-Installer.
MPDCenter, developed by Michael Heidemann, helps you to maintain all your MPD files. You can check for OMR conformity (only formal not the layout itself of course). You can extract models with all depending files. Change Author, License, Keywords, Theme, History and Filetype (LDRAW_ORG line) on the fly for all LDR files in the MPD. MPDCenter is part of the AIOI - LDraw All-In-One-Installer.
A command-line utility to help you replace LDraw parts with no visible studs or tubes with boxes. Saves rendering time and CPU power. LDBoxer is not part of the AIOI - LDraw All-In-One-Installer.
DATHeader, developed by Michael Heidemann, it designed to maintain the header of a LDraw part (*.dat) and a tool for reviewing parts on the PT.
LDCalc, developed by Michael Heidemann, is a tool for calculation of angles and line intersections. It is also a converter between mm and LDU and inch and LDU or vice versa.
LDPartEditor, developed by Nils Schmidt, is a platform independent CAD tool for LDraw parts.
LDPatternCreator, developed by Nils Schmidt, is a vector based development tool for textured LDraw parts.
LDStructure, developed by Michael Heidemann, is a tool for analyzing ldraw parts library. With LDStructure you will get a tool that tells you which parts are required to show the current part and where the current part is used in. You will get this information within a second or even quicker. So this tool is a "needs to have" if you are working on parts for the ldraw part library.
PrimGen2, developed by Michael Heidemann, based on PrimGen, creates defined primitives that are used in part files.
stl2dat, developed by Marc Klein, is an utilitary tool to convert .stl files issued from cad software like Solidworks, Autocad, and many others to .dat files for ldraw compatible programs.
txt2dat, developed by Ross Crawford, is a utility to produce virtual stickers. It allows you to choose any scalable typeface, and create a LDraw file containing a representation of any string in that typeface.
