Drawing circle on the plane of isometric surface

I am following the isometric tutorial here:

http://wiki.librecad.org/index.php/LibreCAD_users_Manual#Connecting_the_corners 

But I am not able to draw circles on isometric surfaces.
I can draw a regular circle, but it does not appear to be isometric,
meaning it it flat and not in same plane as the rest of the isometric object.  

Please advice.
Thank you.

isometric only means the grid is isometric.

LC is 2D only, so an ellipse should be drawn explicitly as a projected circle.

One way to construct such an ellipse is to draw a projected square, followed by

 Ellipse -> Draw Ellipse Inscribed

to draw the projected ellipse inscribed in the projected square.
