Would you like to create blueprints of your LEGO® constructions on a computer? Then LPub3D will make the process easy for you. The Open Source WYSIWYG program is designed to create and edit building instructions in the LEGO® style digital format. It uses an integrated 3D Viewer that is powered by LeoCAD and the powerful LDraw® parts library.

Using LPub3D

Installing LPub3D required some level of technical skill because we needed to make some configurations. Considering its functionality, however, specifying the paths to the LDraw® libraries and engine is fairly simple for someone who needs to use it. The user must have some knowledge in using graphic or CAD tools.

Apart from the menu and tool bars on the upper part of the user interface, the program window was divided into two panes. The LDraw® File Editor was on the right pane while the corresponding preview appeared on the left. We could change between the file editor and 3-D Viewer via tabs on the lower part of the pane.

We had an unlimited part list, which we could sort by category, color or size.

The LDraw® File Editor allowed us to have a deeper control of our project while the 3-D Viewer enabled us to view our design from different angles as we could rotate it.

Once we had made our LEGO constructions, we could print or export them for later use. We could export to PDF, JPG, BMP or PNG file format. Apart from creating projects, the program allowed us to produce comprehensive manuals for the benefit of the end users. The program automatically generated formatted cover pages.


LPub3D is a free program for creating LEGO® constructions. Please note that the software requires LDraw® parts library and LDraw® engine installed to function effectively, and you need some CAD skills to successfully use it. Its intuitive graphical user interface includes various technical functions.
