lisp to change all polyline in clockwise direction

[Anonymous]

Hi all,

i search a lisp routine to change all selected polyline or all polylines in the file in to the same direction (clockwise).

To do it manual with each polyline is very complicated...

My polylines never include curves, they are allways simple lines. See sample file.

I need it very often to post a cnc code from the drawing...

Anyone knows such a lisp or would be able to post here a code?

Many thanks!

cheers

Ingo
