Принадлежит:

With the development of the industrial technology, the product requirements are diversified and complicated, the product production cycle is increasingly shortened, and therefore how to complete product design and manufacturing within the shortest time becomes an important task in the industrial community. In order to solve the problems that the design process of some products is complex, and 3D CAD data can not be produced, the reverse engineering technology emerges at the right moment. Pro/Engineer operation software occupies an important position in the current three-dimensional modeling software field. The software is set up on a database on a uniform base layer, and once an engineering detail drawing changes, NC tool routes can be automatically updated. If an assembly engineering drawing changes, the whole three-dimensional model can have completely the same response. Due to the advantage, the design is better optimized, the finished product quality is higher, and the price is lower ...
