Pipe layout and assembly technology in virtual environment

Pipe layout design and assembly planning method in virtual environment (VE) with controllable model was put forward. This model was based on control point description to achieve its controllable speciality. The method can improve the efficiency of pipe layout work because this kind of model has the merits of small data package, easy control, high fidelity and is easily to edit or rework. To adapt different requirements of pipe layout work, two kinds of layout method were put forward. To reduce the waste of material generated by incorrect layout result, a method of integrating layout work and assembly planning was brought forward to support the field production. An antitype system has been developed to validate the above methods.
