This IS Chief Architect. Notice the screen grab?
Are all you "members" this bubbly and cheerful? Sorry my version is older than yours.
Just trying to design a pizza oven.
I'll move on.
I'm sure there is a simple way to do this, but I'm a stumped beginner. I'm trying to reflect (rotate) around the Z-AXIS? (see attachments) X & Y axis is no problem.
Thanks in advance.
(Picture in red is what I would like to achieve)
