Here’s a quick tip on something I like to do to increase usability when working with ZModeler.
You spend a lot of time zoomed in with ZModeler, working on verts and edges. I find the little “buffer” zone around the viewport frame that lets you do navigational (pan, rotate, scale, zoom, etc), masking, and visibility gestures even when there’s no empty canvas space, too confining. I like to scroll (the document scroll, not the viewport pan) the document out from the edge a couple inches so I have that whole stretch of empty canvas to navigate or draw marquees with, no matter how far zoomed in I am. Your scroll function will be in a different place, but you can always find it in the Transform menu.
