We have noticed that for mirror C3, the four corners are not on a single plane. When a plane is fit using three corners, the fourth corner does not lie in the plane created. Is this an intentional design for the mirror? Please let us know.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Best regards,<br data-mce-bogus="1"></div><div>Tyler<br data-mce-bogus="1"></div></div></body></html>
