A method and system for indicating curve connection continuity information in a graphical design system comprises steps and apparatus for determining values for measures of G1, G2, and G3 continuity at a junction point between curves. The continuity values are selectively displayed in a graphical display as respective tags adjacent or otherwise associated with the junction point at issue. The tags are updated as the shape of the curves are altered to provide a designer with a substantially real-time indication of the continuity of the curve junction. The display format of the tags can be altered to indicate when the respective continuity measure is within a predefined continuity tolerance level.

Method and system for real-time analysis and display of curve connection quality

A method and system for aiding a user of a graphical object editor in defining inputs for a selected command comprises presenting a navigation console on the display in response to a user selecting a particular command. The navigation console contains information which is contextually related to the selected command and, in particular, shows a sample object having sample features representative of the command inputs and additional features showing the command output using the sample input features. The console display has active regions associated with respective command inputs which cover one or both of a sample feature associated with the respective command input and an icon representative of the respective input. When a user selects an region in the navigation console associated with a particular command input, the command processor state machine is shifted to a state appropriate to receive a definition of a feature in the main object model for use as the particular command input. Similarly, in response to a user defining one input, the state of a navigation state machine can be shifted to highlight element in an active region for a next suitable input to select.
