At present, an important direction of intelligent manufacturing is the product’s Digital Twin, “Digital Twin” means virtual three-dimensional models exactly like real objects, so as to help enterprises optimize, simulate and test in the virtual environment before actually putting into production. If the enterprises have a number of product variants and part type and adopt traditional 3D model assembly method, it will occupy a lot of human resources, and limited by a lot of “constraint command”, it is difficult to quickly modify the 3D model of product variant. This is also one of the important reasons that many companies are difficult to achieve the Digital Twin for their full range of products. In this paper, take powertrain as an example use the shared concepts to introduce the 3D virtual assembly method of a platform. This method can build the accurate and real-time Digital Twin with the help of PDM software. The innovation is: (1) the “without Piles Located on” mode of space positioning method for CAD model is implemented; (2) the platform method for the skeleton model is set up; and (3) the platform management standards for 3D model assembly are set up. It is especially suitable for large-scale virtual assembly models such as automobile and powertrain.
