A mode to snap to the grid can be set in the [[Sketcher_Preferences|Sketcher Preferences]]. The point snaps then to the grid, if it has less than 25% grid distance to a grid line. |

The snap mode does not fix them to the grid. The points can be moved with the mouse or constraints to other locations. |

描述
通过此点工具可在当前的草图中创建一个点,而所创建的点可作为构造几何图形的元素。创建的点将一直作为构造要素,且不会在3D视图中显示出来。
如何使用
选项
可通过设置草图首选项(Sketcher Preferences)中的选项在捕捉网格模式下创建点。此时,如果所创点距网格线的距离小于网格间距的25%,则将被捕捉至网格上。 The snap mode does not fix them to the grid. The points can be moved with the mouse or constraints to other locations.
限制
不能在草图的范围之外创建点。如需在3D视图中创建点,请以零件工作台中的点工具(PartDesign Point)创建基准点,或用零件工作台中的点工具(Part Point)加以取代。
