Abstract: To use tools in a Virtual Environment (VE) for product assembly, a virtual tools representation method based on geometric reasoning is advanced. On this basis, a dynamic building method of a fixed relation between tool and operation object is put forward, which includes three algorithms: geometric constraint dynamic recognition, tool location solving and movement navigation. Users interactively drive tools by using a virtual hand and achieve precise positioning of the operation object. Finally, the methods are validated and an application example is introduced.
