ansys中如何在建立的局部坐标系YOZ平面中画个圆？在操作过程中总提示Arc will be greater than 180 degrees（利用三个关键点时）；cviewing direction is parallel to working plane in window 1（利用圆心跟半径时的警告语）下面为其命令流
wpcsys
wprota,,,90
cswpla,11,0,1,1 ！定义一个局部坐标系
csys,11
/prep7
k,401,0,-4.554794,30
k,501,0,-4.554794,37
k,601,0,-1.054794,33.5
k,701,0,-4.554794,33.5
望大神多指教
