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。
