I made a simple ring with an inner and outer diameter and height. I saved the file, under "Save As" then converted it to G-code and printed the part. Now would like to make the center hole of the ring a bit bigger. I can not find the option. If I click the ring I can change the outer diameter and height only, the center is not available.
Also, if I make the inner hole say 10mm the outer 30mm, and the height 70mm before I hit the checkmark to confirm if I change the outside diameter or the height it automatically changes the center hole diameter.
I am not sure if I am doing something wrong or am missing something simple.
any help would be appreciated I am a new user as you can probably tell.
