Hey guys i am very new in here, you may have seen a few posts here and there by me, anyway... I have an idea for a phone case but i have no idea how to create an exact model.. I have been messing with blender and watching tutorials for what seems to be days. Im starting to get the hang of things in there bu tit doesnt seem to be able to model to an exact size. I also have Rhino but i have no idea how to make a case with it, im just good at resolved items, such as a pen type shape... the issue is my Rhino is just a trial version, is there any software that i can use that is free that i would be able to create exact models such as a phone case? Thanks!
