You can't say "Nobody knows of a method therefore it can't be done". Not that I really doubt that it's true that you can't construct a regular heptagon with Greek construction, but I won't be content until I see an actual proof.
The method I'm using sort of fudges the rules of Greek construction, and it;s quite similar to the method you linked me.
And yeah, Hotrod, those are H1 animations. I imported them into my file to test if they are going to clip my geometry. They do, but no more than they already clipped the original pelican.
It was proven algebraically some time ago (1700's?)
(Also, the second link in my post was my construction using a Neusis construction)
