It is a bug and not a feature. I can take a cube, rotate it in any odd angle then scale it rotate it a thousand times it stays a cube. But if it's in a scene with many props, and not as a subprop, then iClone get confused and the cube turns into a parallelohedron if scaled after several rotations swapping between world to local a few times. But once it is skewable then you can save it as an iprop and can be skewed in a whole new scene even if you zero out all of its setting it will forever skew. I added the iprop for all to try. Just the Y axis (green) still scales properly the other axis are corrupt. Download the zip here: http://forum.reallusion.com/Attachment6251.aspx
I don't see an attached file, but based on the description, I think this might be "expected behavior" and not a bug. Please see my explanation (with pictures) in this Forum entry: http://forum.reallusion.com/296757/Props-skew-instead-of-scale P.S. You can't edit your original entries to add attachments, and you can't add attachments to comments. So if you had an "Oops" and forgot the attachment when you first posted, you're sort of out of luck. You need to create a post in the forum and link to it, like I'm doing here.
