The engineering design process is a creative process and the designers must apply Undo/Redo to modify the CAD model repeatedly to explore new solutions. Undo/Redo has become one of most important facilities in interactive graphics/CAD systems. Undo/Redo in collaborative CAD system is also very helpful for collaborative awareness among a group of cooperative designers to eliminate misunderstanding and recover from design error. However, Undo/Redo in collaborative CAD is much more difficult than that in single-user CAD. For an example, a single erroneous operation can be propagated to several remote sites since the concurrency of CAD operations. This paper presents a multi-user Undo/Redo approach to maintain operation intention and collaborative awareness in full distributed collaborative CAD systems. The paper proposes the composition of 3D designing artifacts and adopts a tree-like structure for representing the combination of features/sub-configurations and the dependency relationship among modeling operations. Based on the feature combination hierarchy, a multi-user selective Undo/Redo approach for full replicated collaborative CAD systems is studded. The proposed method uses site identification and state-vector to track the undo operations. Intention preservation and consistency maintenance are both promised with our method.
