摘要： 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.

摘要： 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.
摘要翻译：编辑三维文字时，使用二维文本编辑模式。一旦三维文本被选择用于编辑，二维文本编辑模式被自动输入，使得用户可以容易地编辑文本。与文本相关联的二维属性在形状的轮廓中显示，使得文本可以被编辑在适当位置。在编辑期间保持2-D属性，例如字体，文本颜色，形状颜色等。二维文本编辑完成后，根据其三维属性重新显示文本。

摘要： 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. As the scene is rendered, preferably slicewise, the level of detail for slices can be adjusted based on predictions of time-to-complete, in order to meet a frame rate target.
摘要翻译：提供了一种贯穿式的三维计算机辅助设计系统。计算要求至关重要，至少部分地通过定义可以显示的整体或部分体积的有界体积或世界。预处理数据有助于组织高性能显示数据。提供全面的细节渲染。然而，在某些情况下，例如在通过期间，图像的一些或所有部分以简化的方式呈现，例如，保持较高的帧速率。基于卷的简化涉及渲染细胞的表面或至少部分地与被显示的物品或系统的部件相交的细胞集合。多个粒度，优选地被组织为八叉树，提供多级细节。通过观看截头锥体剔除并考虑某些细胞面部闭塞情况，减少不必要的渲染负荷。当渲染场景时，优选地切片，可以基于时间到完成的预测来调整切片的细节级别，以便满足帧速率目标。
