Second that

[@Reach3DPrinters]

I think you can select trim, and choose all geometry as cutting, hit ok, then select anything you want to trim off. Like 2 trims at the same time.

[@hughchapman5319]

I really need to use the trim command more

[@raekell]

why not use trim for getting the sides back??

[@nshahirah6671]

if the upper surface and down surface is the same, why don't just use offsetsrf?
