Linear Dimension is there, but can't see it!

I am trying to create linear dimensions on a model and they won’t show up on the screen. I cannot see them. I am in the correct construction plane. If I select all it says there is a dimension there, but…
Have tried to go through all the properties and nothing looks weird.

What working display mode are you using?
Do they show up in Wireframe?

Hi John -

You are right, dimensions were not checked in the display mode.

Thanks, Scott
