摘要 |
A cursor is dynamically attached to a two-dimensional representation of a three-dimensional surface in a CAD system. The system maps input coordinates indicating an initial position and a final position of a cursor to coordinates of a u-v surface representation of a the three-dimensional surface. The u-v coordinates are then mapped to display coordinates. The option to display this cursor on the surface is made by entering a command and by selecting a surface. The cursor preferably includes vectors indicating the magnitude and direction of the slope, and the display includes a window for displaying the u-v representation of the surface. A user can pick points on the surface based on what is visually observed on the display without projecting the point to another surface. <IMAGE> |
