Abstract: Systems, methods and articles of manufacture for editing element attributes of a design within a user interface view are described herein. Embodiments of the present invention relate to reducing or eliminating the effort a user must put forth in editing attributes of a user specified element in moving from the user specified element in a main document window of the user interface to the far end of the main document window and then combing within a dense menu displaying every attribute for every element supported by the user interface. Further embodiments allow a user to easily filter through the dense menu displaying every attribute for every element to find the attributes that are specific to the element selected and do so without having to go to the dense menu displayed on the far side of the main document window.

Abstract: Systems, methods and articles of manufacture for creating an annotated angle with the user specified points are described herein. Embodiments of the present invention relate to reducing or eliminating the effort a user must put forth in creating an angular dimension by drawing two explicit lines or two explicit objects comprised of two lines where either the user would have to ensure the explicit lines intersected to form the angular dimension or define an exact center point to be the vertex of the angular dimension. Further embodiments allow a user to easily create the annotated angle by defining points in the CAD interface eliminating the need to create line geometry with the defined center point in the CAD interface. In one embodiment, this is achieved by the user specifying a start point, a start direction, an end point, and an end direction where the annotated angle may then be created based on the user defined points in the CAD interface.

Abstract: A light-generated input interface is provided using a combination of components that include a projector and a sensor. The projector displays an image corresponding to an input device. The sensor can be used to detect selection of input based on contact by a user-controlled object with displayed regions of the projected input device. An intersection of a projection area and an active sensor area on a surface where the input device is to be displayed is used to set a dimension of an image of the input device.
