查询词典 three parts

In this paper dimension-chain is used to calculate the last effective dimension formed under the influence of tolerances and other distortions. Feature modeling is applied to construct the three-dimension mode of the parts in solidworks. Based on the parametric design function, simulation of assembling result is realized by making use of VB to develop Solidworks. The accomplish of variable parametric design system in tolerance designing is realiazed.
