  • Patent number: 6297798
    Abstract: A method for resolving ambiguities in user input to a computer-aided drawing package. The number of necessary commands is therefore reduced. To draw an element, the user selects a particular drawing command. The user then manipulates a pointing device to select points that further define the position and shape. In accordance with the invention, the point selections can be interpreted in more than one way. A region surrounding at least one of the selected points is divided into so-called intent zones. After, this point is selected, the drawing package monitors cursor movement through this region. The particular intent zone that the cursor traverses determines the interpretation of the point selections following the command.
