Ken,
You will have to extract the edges of the extruded letters first.

You need to extract edges on any surface or solid to use verify, one ,two or dimension.

Then you can dimension them. Or use the tape measure funtion if you don't want to leave the dimesion info on the screen.

Tape measure uses end points, which will work on solids and surfaces. But sometimes end points are not what you need.
