I was revolving a ball for a ball bearing, and i wanted to put the revolution in a circular pattern. When I had a ring between the balls, it worked, but when i deleted the ring between the balls, the pattern disappeared. What should I do?
The pattern must have been dependent on the ring geometry in some way, so that when you deleted the ring, the pattern went with it. That is about the only thing I can think of without seeing the model and patterning technique.
Welcome to the forum. Is that circular pattern in an Assembly or Part? I suspect it's in a Part, and when you created the feature the box for "Features to Pattern" was selected by default. If I'm right you might have better luck choosing "Bodies to Pattern" instead (see Why am I having problems with the Pattern (or Mirror) feature in my Part?).
