Yes, I use select geometry to select all the pieces of something that needs to be rendered, insuring that I get say, the sofa and the pillows on it or whatever generic situation best explains it. Sofa and pillows are separate geometries. After this I type scale $ [.5,.5,.5] and both will scale in relation to different points. Not even uniformly towards their own geometry centers, in example a door and door frame will no longer line up, the door appearing as if it’s scaling towards the origin or something, while the door frame scales towards its central point. Going to test the previously mentioned cube method shortly and hope that fixes my errors.
Khameleon’s box technique works perfectly! Thank you all very much for your vast wealth’s of helping knowledge.
