[Affinity Designer: measure line/path length]

I am here for the same thing. I just want to know if what measurements my lines and curves are! I am also using affinity for drafting sewing patterns. 

[Technical Drawing with Affinity Designer]

I think I am looking for the same thing in designer. I just want to draw lines to exact measurements so I can draft out sewing patterns. I usually do it with paper, pencil, and ruler, but being able to do it via computer would be so useful.
