3. CAD - LDD

We used LEGO Digital Designer 4.1.7 to do the Computer Aided Design (CAD) modeling of our lunar rover. A selection of LDD CAD files is attached.  You will need LEGO Digital Designer (4.1.7 or later) in order to open these files.  You can get LEGO Digital Designer as a free download from LEGO by clicking here.  Warning - This is a large file (135MB).  The latest version of LDD was 4.1.8 as of August 18, 2011.
