Regulating systems ( balances ) with variable radius of gyration are allowed provided they comply with criteria one ( a ) and one ( b ) 带动摆轮旋转的摆碟、调校等时节拍的结构和快慢针等机制及其零件,都必须达到法则1a和1b的要求。
Improved modeling tools and enhancement to many existing commands . examples include better variable radius blend tools , improved booleans , and maybe shelling 强化许多原本存在的建模工具,像是提供更多变化的曲面接合功能,改善布尔工具,或是增加表面厚度的功能。
After direct manipulation of radius , constant or variable radius area in mesh model can be modified quickly and exactly . using this method , rounding shape of a part or die can be directly modified on shell meshes for finite element analysis . ( 3 ) data segmentation on shell meshes is studied 对于已有的圆角过渡区域网格,根据圆角过渡特征与基网格面的相切关系以及给定的新的圆角半径,计算出轮廓线上各顶点对应的坐标,直接修改顶点的坐标值,保留网格模型原有的拓扑结构,使形成的新的网格与原有网格融为一体。
