Is there a way to to do an A-B plot using a given distance between the A-B measurement? Ex. points are based off A and B being 12' apart.

I'm creating a freeform based off of a given distance between point A and point B. I need to use this distance to find all points creating the freeform image. Is there a way to also make sure all points are labeled when making the freeform also.
