By "floating" I mean a dimension without an endpoint, like the 2.625" and 3.75" dimensions on the ends of the "cone" in the Reducer Coupling exercise step 4, https://learn.onshape.com/learn/course/introduction-to-part-studios/basic-features/exercise-reducer-coupling?page=2 ?

As a bonus, how to declare it as the diameter of a circle, i.e. the leading "slashed" 0?

    Thank you, I missed those instructions and then I didn't follow them correctly at first, the following worked for me:

    Create a sketch with a

    1. Select Dimension icon in the menu bar
    2. Select the endpoint on the profile you want to dimension
    3. Select the line, not the origin or any other point that may be on the line
    4. Drag the mouse below the line. if you inadvertently move the mouse
      above the line it will initially show distance from point to line. Don't worry
      move the below the line and it will magically show a diameter dimension.
    5. Now click and then enter the desired dimension
