problem with slice symmetry java script from keyvis

[piotrek255]

Hi

I cant get this script to work with softimage 2012 SAP, it works just like 3dmax's symmetry modifier which is an awesome tool.

http://www.keyvis.at/cg-tools/

This Command mimics the 3ds max Symmetry Modifier.
First it creates a Curve Rectangle of the size of the selection BBox, then applies a Slice and a Symmetrize Op to the selected polymeshes and links their Custom Planes to the Rectangle.
The rectangle can now be used to define the symmetry plane.
Since the factory Symmetry Op does not have a convenient option to link it’s symmetry plane to an object (as the Slice Op does), SCOPs are needed on the Symm Op’s Custom Plane’s posx, posy, posz, rotx, roty, rotz parameters.
Note: this does not circumvent the problem in Softimage that you cannot work beneath Topology Operators in the Operator Stack and see the end-result live.

Usage:
- Select one or more object(s).
- Model > Modify > Poly.Mesh > SliceSymmetrize.


can someone please help me to get it running on softimage 2012 SAP?
