We can make circles (and other things) using the SIZE X Y Z command. I made circles using the LOGS. Size appears to be 1x1x1 up to 16 x 1.
At the top of this screen shop is a shape resembling a canoe. I made the canoe using the size 12 3 1 command. Gives the 12L x 3 wide by 1 deep.
Using this command is going to be a blast to experiment with.
