How can I cut a section out of the middle of a solid object, shortening it? For example if my object was this couch:
How could I make each of the cushions 20cm narrower, without scaling the entire object down?
I’ve read the solutions at forum post “Make the 3d models longer or shorter”.
But those solutions don’t seem so easy to apply. Like the couch, my real object has sort of messy geometry at each end and thus it’s hard to imagine correctly selecting all the relevant geometry. I wish to shorten my object by a given distance (say .2 inches), removing a section from the middle.
