I'm building a model of motorcycle parts. I made the chassis. Here is the link: http://shpws.me/np13 Obviously not modify the dimensions so that later they can fit different parts. Original Bounds In: 1.9 w x 8.5 d x 5.2 h (Cm: 4.9 w x 21.7 d x 13.1 h) But disappointment! : Oriented Bounds (used for determining printability) In: 1.9 w x 8.6 d x 4.6 h (Cm: 4.8 w x 21.9 d x 11.6 h) Does anyone know why this happens? What do I have to do to keep the original proportions? Thank you very much!
