Abstract
Digital Fabrication has become familiar to ordinary people, but making data for digital tools such as a Laser cutter using CAD is difficult for beginners. We developed an easy to learn and accurate CAD interface for tablet “Drafter” based on stationary metaphor. We compared Drafter and present CADs by experiments consisting of both drawing part and questionnaire part. The drawing part showed that Drafter is easier to learn than present CADs, has the same accuracy as present CADs. The questionnaire part showed that Drafter has the same accuracy as present CADs, and is better at usability than present CADs.
