When creating a Break Out View I can't select the "section all parts" check box. Any idea why?
Yes
Look as the Participation for the parts, some CC parts are set not to participate in Section Views and a Break-Out is a section view, "sort-of".
Where would I check for the participation for the parts?
Have you choose a depth first? It doesn't allow to mark Section all parts untill you set the depth
Can you tell us a little more? Like are you making the break out view from a typical view or a section view or other view. Also have you make sure that you saved the assembly file before opening the drawing file and creating the view. I tried several different configuration and I had the section all option in all of them.
