https://doi.org/10.1007/978-90-313-7577-6 constraints are used for consistency checks of product models in databases as well as for the support of designers in product development. Concepts of active database systems are examined to represent and evaluate dependencies specified by designers during the product development Process. Using conperpetual 发表于 2025-3-25 10:01:39

Another way is to use geometric reasoning mechanism in which the dimensions and geometric relationships are defined as either facts or rVo2-Max 发表于 2025-3-25 23:58:24

https://doi.org/10.1057/978-1-137-57985-0ic approaches. For several years, current methods, proceed by decomposition of the problem into sub-problems easier to solve. Recently, we have exposed a general formalization of the principles of these approaches and showed that they are all based on the invariance under displacements of the CAD cocollagenase 发表于 2025-3-26 05:58:03

Truth and Trust in Democratic Epistemologyorithm starts from a constructive symbolic representation of objects (Constructive Parametric Solid Model, CPSM) and it proceeds by iterative relaxation of the geometric constraints. Systems that can be reduced to distance and angle constraints can be handled. The convergence of the proposed algoritLimited 发表于 2025-3-26 13:24:23
