Lithium™ is Ashlar-Vellum's entry level 2D CAD application for macOS and Windows which is intuitive, easy to use and provides all the necessary tools for creating professional 2D drawings or 3D wireframe designs. Lithium™ is built on the same engine Ashlar-Vellum’s Cobalt™, Xenon™ and Argon™ are built on, therefore offering full file compatibility with these apps. Lithium™ files are not, however, easily translated into our Graphite™ professional 2D/3D wireframe drafting program which is built on an entirely different chassis. Lithium™ supports a large number of file formats for import and export including DWG, DXF, PDF, AI, JPG, PNG etc.
