I was trying to print this protractor http://www.thingiverse.com/thing:927706 and I couldn't see if the numbers got sliced properly. So that made me think to ask if there is a zoom feature when you preview your sliced model. The numbers don't print btw. If anyone else wants to try please let me know your settings and if it works.
If I use the scroll wheel I can zoom in on the sliced model. Is that what you mean?
On Mac it is just a two-finger slide up/down on the trackpad. It's been there as long as I can recall.
Ha. Don't I feel stupid. Never used a mouse with scroll wheel on my laptop. It works perfectly.
Nothing stupid, but I just can't imagine how you've been dealing with any slicer software at all really? They all kind of use a similar user interface.
