Rotate but not scale
 

I've a problem with my rotate.

I've applied a image to a polygon plane flat on the ground (i.e top view).
When I rotate the plane so that it faces me (i.e. front view), the plane becomes shorter!

How can I solve this?

Thanks in advance!

More information:

That happens when I create the default plane with 10 by 10 intersections and deleting a few intersections/faces off.

I've got a workaround but why does Maya behave in this way?

well if you're deleting faces off of the plane, isn't that what's causing your plane to become shorter?

It's probably in a group or parented to something. Remove it from the grouping relationship and it should be fine.

Thanks.
It worked!
