BricksViewer is a Java application/applet for viewing LEGO® .lxf scene files.


  • Provide an application which will allow anyone who can run Java to view LDD models/instructions
  • Provide an applet which will allow users to highlight their models on their web sites


TLG released LEGO® Factory in August of 2005. When used in conjunction with LDD (LEGO® Digital Designer) 1.4, LEGO® Factory allows users to build models in a CAD environment, upload the model to TLG's website, and then purchase the model and/or allow other users to purchase the model.

Currently, the build instructions are the CAD file produced by LDD1.4, which can only be viewed in LDD. I believe there will be a market for purchasing these models which will grow beyond the group of people producing them. Unfortunately, not everyone can run LDD1.4 due to OS, graphics card, etc.
