谢谢，你说的对。若按sketch in place而非sketch on workplane，选part上的面（或part坐标系的xy等面）画线就不会出现此问题。% q$ a: m, ^ v1 d9 J
帮助提示：If you pick a point or vertex on the same part, a blue focus point is projected to the workplane. (If, however, you pick points or vertices from different parts, a yellow focus point is projected onto the workplane and relationships are not maintained.)

必需点选画图的四个钮才有右键的下拉菜单.)
