Hello. I am a bigginer and want to rotate a circular surface in XY plan to be in YZ plan. The (rotate,axis,angrot) command for rotating the view only. Your help is very much appreciated. Thanks in advance and best regards. Wael

Look vor VGEN command. You'll need also to define an apropriate coordinate system for it

Dear Mr. Anton Lyaskin Thank you very much for your reply and sorry for my late response. I tried VGEN using different coordinates but I faild to rotate the circle. The circle origin is 0,0,0 and it is in the XY plan and I want to rotate it around the the Y axis, so it would be in the YZ plan, that is all. I wonder if you or other one have idea for that problem. My best rgards.

As Anton said you can do it using VGEN command or VTRA but first you have to define a coordinate system (CS) that you'll use for the rotation. If you prefer VGEN you have to create a new local cylindrical CS with x-axis same like the global cartesian CS, and y-axis matching the z-axis of the global cartesian CS. Then the tangential direction of the new CS is the direction you have to regenerate you vertices along. If you prefer VTRA command just create a new local cartesian CS which will have its x-axis aligned with z-axis of the global cartesian CS, y-axis will match y-axis (the rest is not important). The rest of the procedure is up to you and prostar help. hope it helps

Dear Vladimir, Thanks a lot, you clarified every thing and helped me a lot. My best regards.
