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.
