Dept. of Subtle - Active Workset is Off

If you have turned off the Active Workset you may have noticed a couple subtle items are missing. First text won't show you leaders as you pick points to create them until you finish the text. Second is the Rotate tool's Origin of Rotation icon, it doesn't show up either. Turn back on the Active Workset and they start feeling better.

If you can't see your sketch lines while creating a sketch based element like a floor, ceiling or roof for example, you just need to check the Visibility/Graphics settings for Lines. When this category has been turned off you lose all the elements that use these various line styles.

I've recorded a short video to explain this stuff visually. You can listen and watch here now.
