Vertical circles

Hi! I need to draw a vertical circle (see the picture that I attach) and I do not know how to do it. ¿Anybody can help me? Thank you!


you can either align the screen to that view and try drawing…or try hitting the left or right cursor key, it should force the circle to draw on either of those axes…looks like in the example it would be the right key for the red axis.

Or you can draw the circle flat in the XY plane and then use Rotate to move it vertical.


Thank you all for your help
