Abstract: A system may cause a display device to display a graphical representation of a geometric model of a part having a plurality of features that are individually selectable in a work space of a graphical user interface and may receive a selection input representative of a command to select one or more features of the geometric model. The system may also determine at least one displayed characteristic capable of being visually perceived by a user that the geometric model or a portion thereof has with respect to the workspace in terms of size, orientation, and/or position. Also, the system may carry out a first selection from among either a coarser selection of the features or a finer selection of the features of the geometric model based on an input location and based on the determined at least one displayed characteristic of the geometric model or portion thereof.

Abstract: A system and method is provided that facilitates perception-based selection of features in a geometric model of a part. A processor may cause a display device to display a graphical representation of a geometric model of a part having a plurality of features that are individually selectable in a work space of a graphical user interface. The processor may receive a selection input representative of a command to select one or more features of the geometric model, which selection input specifies an input location on the workspace that coincides with a location on the geometric model. The processor may also determine at least one displayed characteristic capable of being visually perceived by a user that the geometric model or a portion thereof has with respect to the workspace in terms of size, orientation, and/or position.
