LCad and LDraw are the two programs used by the vast majority of folks who do Lego design on their PC's (and on their MACs). While, it is not the product used by the official Lego design teams, they, in combination with a variety of other products, are very powerful 3D CAD based design software for building Lego models virtually.
From this page you will find links to MLCad work I have done. Both small scale components, and larger models. If you'd like to download MLCad for youself, you can do so from the LDraw.org website's Downloads Page.
This section holds all of the complete Lego models I have designed, such as the Ripley-class destroyer shown at the left. These are stored in either .LDR or .MPD format (depending on the complexity of the model), and then zipped for ease of downloading.
These MLCad files are of smaller pieces of models, such as the weapons pictured at the right. These are all stored in MLCad's native .DAT format, to make importing them into other models easier. Again, these are packaged in .zip files to make downloading them easier.
