Hi

is it possible in XSI to mirror an polygon??

If you mean what I think you mean, then, and there might be an easier way to do this, you'd select your polygons and go to Create, Extract Polygons (Keep), and then for whichever axis you wish to mirror the polygon across (X, Y, or Z), you'd set that axis' scale value to -1. Don't forget to freeze the extracted mesh's transforms after scaling, though!

If you mean mirroring an entire polygonal object across some axis, then you could either do what I said above but select all of the object's polygons, or you could select the object and go to Edit, Duplicate/Instantiate, Duplicate Symmetry.

I suggest you read this page from the User Guide: http://softimage.wiki.softimage.com/xsi ... bjects.htm

Thanks. It works

Make a polygon selection then right click and select Symmetrize Polygons.
