So I've made the design from sketch, I revolved and made into a full modeled object and eventually made into an stl. Now I wanna go back and add/change to the design but when I try to I end up "drawing in the air" like it wont attach onto it. Not sure what I am doing wrong and it's really frustrating. Please any help will be appreciated. If you need screen caps I can post later today.
