CAD systems are very useful tools in the industry, because they help design processes and new product development. However, it requires new mechanisms of interaction to provide greater usability of these tools. This usability can be provided through new interaction devices such as Kinect. We describe a methodology to find a series of gestures makes by the hands for control a CAD system with Kinect sensor of Microsoft. These gestures must be easy to remember for the user of the system and they don't should represent a cognitive load to make the design's experience most interactive.
