Abstract: A two-dimensional text editing mode is used when editing three-dimensional text. Once the three-dimensional text is selected for editing a two-dimensional text editing mode is automatically entered such that the user may easily edit the text. The two dimensional properties that are associated with the text are displayed within an outline of the shape such that the text may be edited in place. The 2-D properties, such as font, text color, shape color, and the like, are maintained during the editing. After the two-dimensional text editing has been completed, the text is redisplayed according to its 3-D properties.

Abstract: Methods and systems for associating two objects in a drawing application with one another are provided. Embodiments of the invention are directed toward a method in a computing environment that includes receiving a command to designate a target and designating the target. The method can further include identifying a subject and providing a suggested association of the subject with the target. The method can still further include receiving a command to accept the suggested association and associating the subject with the target as suggested.

Abstract: A fly-through, three-dimensional computer aided design system is provided. Computational requirements are bounded, at least in part by defining a bounded volume or world defining the volume which may be displayed, in whole or in part. Preprocessing the data assists in organizing the data for high performance display. Full detail rendering is available. However in some situations, such as during fly-through, some or all portions of the image are rendered in a simplified fashion, e.g. to maintain a high frame rate. The volume-based simplification involves rendering faces of cells or collections of cells which are at least partly intersected by components of the item or system being displayed. A plurality of granularities, preferably organized as an octree, provide multiple levels of detail. Unnecessary rendering load is reduced by view frustum culling and considering certain cell face occlusion situations.
