This (commercial) utility I wrote draws a grid of them that fit
inside a polygon.
http://www.ctmap.com/gisnet/catalog/sw/hexgrid.html.
But the dead easy way to draw one hexagon at a point (if you
don't care about its orientation) is to create a buffer with only
6 sides:
objHex = buffer (objPnt, 6, 100, "ft")
which creates a hexagon with a 100 ft radius.
To create a region object with any rotational orientation is a
bit harder, especially if you want to use spherical trig to get
the distances and areas right.
