mirror image

[blouie]

I am new to esprit 2008. I was wondering if someone could explain
how to mirror a 2d image drawn in the xy plane.I want to mirror
it about a line drawn in y axis. Tried the F1 help but couldn't get it to work.
thanks

That's easy.
Scale the Y axis by Minus one.
It will be easiest if your Y0 reference is along the Y centre line
It will flip around Y0.

If you scale both axis by -1 then you have done a 180 deg rotation around X0 Y0

See the attached diagram. The scale idea suggested above doesn't work in Esprit.
