I was unable to determine if dimensions and/or dimension lines could be
displayed. Is there a setting which causes dimensions to display, or is
that something available only in the Pro version?

(Yes, I know the small box down on the right has the dimensions of the
selected item, but that's not the same as displaying dimensions lines.)
Answering my own question

I spent over an hour trying discern how to do this last night, even
watched their online video for 20 minutes and finally gave up. Of
course right after I posted this this evening, I came across their
online documentation and the answer was right the Tools-Dimension
then select the segment you want to display a dimension and pull a
dimension line off it.
