Precision sketching: the fun way to design.™
It sounds like an oxymoron: sketching and precision. But not anymore. Now you can create and revise precision drawings as fast as your ideas flow. Change your mind? Get a better idea? No problem. Sketch what you envision with as much or as little precision as you need — so easy even non-CAD users can get their ideas across accurately and with speed.
The Vellum® magic strikes again with wireframe sketching so intuitive it anticipates your next move, using our unique Drafting Assistant, as it moves with you from idea to idea. Lithium is great for floor plans, landscaping and garden layout, electrical diagrams, home remodels and makers of all kinds.
