Perspective grid questions

[media kat]

I want to draw squares on a floor in perspective.  I am able to draw lines along the one point perspective grid on the left hand side of the artboard but not on the right.  How do I get the lines on the right hand side to show up so that I can draw along them as well.  I could just copy them and then reflect them but there must be a way to have the one point perspective show up on the right hand side of the artboard.

Thanks in advance

It's kind of silly but you can't get a vertical plane on both left and right sides at the same time.

In order to draw on the right side you can hold down the 5 key and draw in perspective on the right.

If you hold down Option or Alt and 5 you can copy objects on the right plane all along the ground plane.
