I haven't plotted this so apologies in advance if I'm wrong, but given:
__________ ________
/ \ |
/ \ |
/ \ | h
/ .x,y \ _____|_
\ /
\ /
\ /
\__________/
|_______________|
3h
the 6 corners should be:
(x+h), (y+h)
(x+h), (y-h)
(x-h), (y+h)
(x-h), (y-h)
(x+1.5*h), (y)
(x-1.5*h), (y)
In British National Grid its easy if h is given in metres, you may need to do some
conversions depending on your coord sys

Does anyone know how I can make a mapbasic program to draw hexagons? I have
been trying in vain to calculate angles etc. The idea is that the user will
click a location on a map and the program will ask for a cell size, then
draw a hexagon with a centroid at the place where the user clicked. I can
get everything to work, except the drawing of a hexagon!!! Any help anyone
can give would be greatly appreciated!
