The expert suggest to It is in feature mode, I just went ahead and used the circular patterns in my sketchs, thanks.


2. The holes show up in the preview function while creating the pattern, but disappear as you complete the pattern.
the expert also suggest use in feature mode, but here is the part I dont understand though

The problem you're seeing is due to the fact that the original Hole Wizard feature you created just shows the original component it cut in the Feature scope for components affected by the Hole Feature. When the feature is circular patterned the pattern feature gives no option for additional parts to intersect. To fix the issue modify your Hole Wizard Assembly feature to include any components that you want to cut when patterning the Assembly feature.

The original Hole won't cut the other components but when it's patterned the holes will appear in any components selected in the Feature Scope Group box. These components must be selected manually in the original feature see attached file.

it end up myone has a small gap in between, it shows the advantage of using divide operator, as it always leave the decimal place.
