Product multi-level parametric design technology based on skeleton model

To resolve the problem of lacking tools to sustain the Top-Down decomposition of parameters and multi-level parametric drive modeling based on skeleton, the technology of product multi-level parametric design is put forward. This technology takes product control parameters and constraint relationships as the core. The technology of product decomposition modeling is studied to obtain the control parameters and constraint relationships. The product multi-level parametric skeleton modeling technology is studied to obtain skeleton constraint model based on the technology of product decomposition modeling. A new product instance can be obtained rapidly by changing control parameters of the skeleton constraint model.
