Abstract
AbstractWe develop a Computer Aided Design (CAD) editor using an open source library, with the aim to minimize the cost in the future, as compared to the development of conventional editors, and to accelerate the expansion by means of standardized languages making the development easier. We focus on snapping, a very important area in computer graphics and without a CAD application inconceivable. CAD applications offer the possibility of snappings to allow the developers an intuitive interaction with the objects in 2D or 3D space. Snapping allows by using constraints the merging of multiple objects into a new object. Two possible approaches for implementing snappings are addressed and presented. Advantages and disadvantages are discussed via a user study.KeywordsIntuitive PlacementIntuitive InteractionConventional EditingCrack PointContext WindowThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
