I'm a total noob and following this beginners tutorial. My aim is developing some smooth models to print in my 3D-printer (which is impossible with Tinkercad which I've been using up until now). At this point in the tutorial he says I need to "apply the scale" and he shows how I should do it. Unfortunately it doesn't work for me. I recorded a short screencast to show what's happening here: https://www.youtube.com/watch?v=T25aDFLxuhc
Does anybody know what I'm doing wrong? Why can't I apply the scale and why can't I zoom in further?
