Abstract: The use of virtual reality technology for assembly training can provide an interactive and intuitive learning environment, enhancing learners' practical skills. However, the current methods for creating virtual assembly training content have limitations. Animation-based content requires manual arrangement of animation sequences by experienced users, which is inefficient. Interactive content based on the ASP algorithm incurs high computational costs and relies heavily on CAD data, imposing strict requirements on the model data. Furthermore, user interaction is constrained to the optimal solution calculated by the ASP algorithm, limiting the range of possibilities. To address these issues, we propose a framework called CRUD for the rapid construction of virtual assembly prototypes. This framework supports multipath assembly, enabling the simulation of real-world assembly scenarios. It can be implemented using common game engines, allowing end users to create virtual assembly sequences through simple configurations. We demonstrate the effectiveness and universality of the framework using a complex mechanical assembly case. We argue that enabling multipath assembly support in virtual training represents a significant step in making virtual simulation more realistic and practical.
