Thanks for the help.  I ended up using a polyline rectangle then extruding it using a taper.

Use the pyramid command to make a square base, after finished with the command, hold Ctrl and pick the midpoint of a base line, stretch the distance needed, escape, hold Ctrl and pick the top of the pyramid, stretch that half the previous distance.

that sounds like a lot of work.

I think I'll stick with Loft to Point.

No calculations needed.
No editing needed.

I'm kind of lazy.

Same amount of work, and I like the huge challenge of dividing by 2.

 

Here's an idea, in the future just suggest your own solution, no need to critique other's.

I don't know if I met you before or if you are someone important here.
I can only assume by your response that I offended you.
I simply don't care, so I will continue to offer critique and opinion where I feel appropriate.

 

If you are offended by a post there is a mechanism here to report inappropriate content

The  Loft command is a general solution that can be used to solve a problem of the type described by the OP for nearly any base profile shape.

 

In my opinion you have raised a more fundamental concern - the censorship of critique.

 

While this site might not be the appropriate forum to raise opinions or critique all of human concerns, it would be a less useful forum, in my opinion, if discussion of CAD techinques and preferences were censored here.
