All manholes that you add to the map start as Clear. Here's how to make them show up as Not Clear, and how to turn them back to Clear.
1. Click on the manhole that you want to mark as Not Clear.
2. Select Edit.
3. Click on Not Clear on the pop-up menu. Part of the menu, and the manhole, will turn red.
4. Hit Save in the lower right corner.
To change a manhole that is currently marked as Not Clear to Clear, do the exact same thing, but click on Clear in the pop-up menu. This will turn the manhole green.
