I have placed a callout on a plan around a column which will refer to a detail which I had drawn previously. I set the callout to be a callout only and not generate a title. I made a view of that drawn detail in the project navigator, and dragged the callout from the plan view onto the detail, then dragged the detail onto a sheet. Then I placed a title on the view detail. the callout refers to the sheet just fine but the sheet with the detail title only has ? marks. why is that? If someone could tell me the proper order of ops for previously drawn details that would be great!
