Hi guys/gals,

So one of the things I like to play with is trying to model objects in older versions of Alias, but one of the most significant hurdles I run into is being able to make a mirror of an object. Alias 9 and above added a mirror option, but like many things there was probably a way to do it before hand, but with added steps.

Does anyone know how to do the equivalent of "mirror" in Alias 8 or earlier?

I created a surface I want to mirror in Alias 7.5 - wire file can be found here http://www.mediafire.com/file/aos9w5omsel4hk0/how_to_mirror_this_surface.wire/file

Here is the wire file under Alias 9.6 with the location of the mirror option:

Here is the surface with 4 mirrored sections - seems the surface has pretty nice continuity!:

Any insight would be awesome!

special thanks to drmadison for explaining this to me - the trick is to duplicate the object and change the scaling, not any translations. So using Alias 7.5, here is how I made the same mirrored surface using the scaling parameters:
