描述
此工具将创建一个新的草图(sketch)。
请注意,零件设计工作台(PartDesign workbench)有它自己的创建新草图命令,当您使用零件设计工作台时,它将采用自己专属的新建工具。
如何使用
若未(预)选特定面,则点击此图标将弹出一个对话框,问您是否将草图绘制在
- XY-平面
- XZ-平面
- YZ-平面
在此,您也可以改变至上述任意一种平面的偏移值(offset),以及在上述平面的哪一侧计算偏移值。
在已有特定(预选)面的情况下,点击此图标将把草图映射至选中的面上。
备注
通过映射草图(Map Sketch) - 命令可将草图重新映射至另一存在的面上。
利用方位(Placement)属性可把草图移至3D空间中。
