    Creating flat patterns is a beautiful, yet, complicated mixture of art and engineering. A tool should support the process rather than adding another layer of complication to it. White Rabbit CAD is made with that in mind and won't get between your ideas and the lines to show them.

    There are a number of different tasks associated with working on clothing patterns. White Rabbit CAD supports as many of them as possible to become a one-stop-solution for most situations. From creating patterns from scratch to tracing and reworking existing patterns, from printing them in a variety of ways to archiving them and even preparing patterns for sharing, there may be little to no need to involve any other application in the process.
