Hi Michael T.

>Do you have access to a system with direct modeling capabilities such as delete surface etc.?
In MoI I can delete machine area just by hitting "delete". But this not easy task to bring the trim surfaces to the initial shape. Do you have experience on this area you can share...? Not only use MoI, if you have another software that can help it will be good... At least I can follow the trick.

Thanks... ;)
