I'm having a lot of trouble in making the insertion of a new body because every time I make it the original body disappears. That happens when I try to make a boolean operations or helix.
here is the solution
If i remember right the Tools bar there must be only current body option. check it and turn it off. (remember this "orange icon means active") tomorrow i will upload image.
Özgür Kesebir, thanks for your answer, but I didn't understood what you meant. I will wait for that image. Thanks a lot.
