This i my new version of the polygon tool for openscad
How it works ?
See:

It generates a openscad file but this time it writes modules so you can use it as a library.

O there is also a online version

You can now:
move the points :-)
delete points
add point
add points to a closed path(shift drag in add mode)

add modules
delete modules
duplicate modules (handy)

dont forget to set openscad in automatic reload for more fun instant update

Please let me know what you think of it
