In order to realize the input and output ofconceptual sketch,an interactive sketching design method based on pen is described. First,the methods for automatic segmentation,recognition and regularity of single sketching stroke are presented.Then ten kinds of pen-based are designed and used to edit the conceptual sketch,such as delete gesture,move gesture,copy gesture,rotate gesture,etc. These gestures are recognized by using the perceptron algorithm.Experimental results show recognition rates over 97%.After that,the exchange format files(DXF)is output from the system and integrated into other CAD systems.The example shows that the sketching edit method using strokes and gestures improve user adaptation and intelligence of CAD systems.
