I have Solidworks 2015 and in the first attached photo is my drawing. As you can see the hole dimension is a .25 diameter. I put this on the drawing sheet by using the "model items". I cannot get this Linear dimension to a Diameter dimension with just 1 leader. I have tried to find a command (apparently Display as Diameter) and the internet says it exists, but not on my machine? Under the Witness/Leader Display there is no icon and I can't get a right click to show "Display as Diameter". I do get "Make Radial", but that is not what is needed here.
