几何图形 (Geometry)
5.15几何图形 (Geometry) 1：几何图形 (Geometry)  1）创建圆心和椭圆中心 (Create circle and ellipse centers) 2）允许直接操作-“在前面课程已经有详细的介绍” (Allow direct manipulation) 3）显示HV工具控制栏(Tools Palette) 4）复制生成的几何图形时创建端点 (Create end points when duplicating generated geometry) 2：创建约束 (Constraints creation)  1）创建基于特征的约束(Create detected and feature-based constraints) 3：智能拾取... (SmartPick...)  1）支持直线和圆 (Support lines and circles) 2）对齐 (Alignment) 3）平行度、垂直度和相切 (Parallelism, perpendicularity and tangency) 4）水平和垂直 (Horizontality and verticality) 4：约束显示 (Constraints Display)
1）参考尺寸大小 (Reference size) 2）约束颜色定义(Constraints color) 3）约束类型... (Constraints types...)
A：水平 (Horizontal) B：垂直 (Vertical) C：平行度 (Parallelism) D：垂直度 (Perpendicularity) E：同心度 (Concentricity) F：相合 (Coincidence) G：相切 (Tangency) H：对称 (Symmetry) 4：颜色 (Colors)  1) 可视化诊断颜色定义 (Visualization of diagnosis)
A：过分约束的元素 (Over-constrained elements) B：不一致的元素 (Inconsistent elements) C：未更改的元素 (Not-changed elements) D：等约束元素 (Iso-constrained elements) 2）其它元素颜色 (Other color of the elements)  A：构造元素（对于 V5 R11 以前的工程图）(Construction elements (For pre-V5 R11 drawings) B：智能拾取 (SmartPick) |
