    摘要： A system, method, and computer program for determining a visibility solution of a model comprising the steps of rendering a model having a plurality of parts with at least one color value encoded for an at least one corresponding surface identity; distinguishing a plurality of exterior parts from a plurality of interior parts based on said at least one corresponding surface identity; and identifying a plurality of features in said model not copied into a composite image and appropriate means and computer-readable instructions.

    摘要： Most three dimensional geometric modeling programs employ a feature-based parametric modeling technique. A modification attempted by a user in a feature-based parametric modeling may provide a result different than that expected by the user, since most edits require a 'roll back' of a history tree to the state wherein the geometry was originally created. Upon completing the edit, the tree rolls forward, taking into account the changes you have made. A problem arises when a parent feature is destroyed and now a child feature can no longer properly bind. The disclosed invention solves this problem by rolling back the tree to find the last successful bind made by the child, and then roll the model forward such that all downstream binding occurs with the successful bind in tact.

    摘要翻译： 大多数三维几何建模程序采用基于特征的参数建模技术。 用户在基于特征的参数建模中尝试的修改可以提供与用户期望的结果不同的结果，因为大多数编辑需要历史树的“回退”到其最初创建几何的状态。 完成编辑后，树将前进，同时考虑到您所做的更改。 当父功能被销毁并且现在子功能无法再正确绑定时，会出现问题。 所公开的发明通过回滚树来解决这个问题，以找到由孩子做出的最后一次成功绑定，然后向前滚动模型，使得所有下游绑定都以成功绑定的方式发生。

    摘要： A method and related CAD system and computer readable medium for creating a dimensioned object model in a CAD system, including automatically associating editable dimensions with an object model in the CAD system. The method includes receiving 2D CAD data, the 2D CAD data including dimension information, and creating a 3D model corresponding to the 2D CAD data. The method also includes associating the dimension information with features of the 3D model and storing the 3D model and associated dimension information in the CAD system. The dimension information can thereafter be edited to automatically produce corresponding changes in the 3D model. Other methods are also described.

    摘要： Most three dimensional geometric modeling programs employ a feature-based parametric modeling technique. A modification attempted by a user in a feature-based parametric modeling may provide a result different than that expected by the user, since most edits require a 'roll back' of a history tree to the state wherein the geometry was originally created. Upon completing the edit, the tree rolls forward, taking into account the changes you have made. A problem arises when a parent feature is destroyed and now a child feature can no longer properly bind. The disclosed invention solves this problem by rolling back the tree to find the last successful bind made by the child, and then roll the model forward such that all downstream binding occurs with the successful bind in tact.
