can someone tell me how to trim the OTHER part of my solid with a brep?

Hello

I am trimming a series of solids with a brep.

They trim all right, but unfortunately, the brep is cutting away the wrong half of my solid. I'd like to cut the other part. 

I tried to "reverse" both input and output. No luck.

Thanks! Ivy

Got anything to look at?

Solid trims use the normals of the objects doing the cutting to determine which side to keep, so if your cutting brep is a surface it should work to "flip" it.  If you're using a polysurface for the cutting, you should be able to explode it, flip each face and rejoin them.
