Precision sketching: the fun way to design Lithium is an entry level drafting and sketching program for product and building ideas. Based on Cobalt, it has great precision and easy to use layers, and will not include some of the more professional drafting features of Graphite, such as model-to-sheet, view ports or parametrics. Create and revise precision drawings as fast as your ideas come. Use as much or as little precision as you need. So easy even non-CAD users can get their ideas across accurately and with speed. Available on both Mac and Windows, Lithium is an excellent way to step into the world of 2D/3D sketching using our unique Organic Workflow™ non-linear design process.
