Objet: MI self-crossing polygons
Hi there
Is there any way of automatically finding and correcting self-crossing
polygons ?
I have created some regions containing polygons. These polygons are
automatically created from coordinates, but sometimes the same polygon can
end up using the same coordinate several times. I believe this is why I
should see the polygon as being self-crossing. None of the lines cross, but
there are corners that use exactly the same coordinate.
I need to perform some 'Objects Combine', but can't unless the polygons are
flawless. Since I have a lot of polygons to combine it would be impossible
to do the work by hand.
I could of course make a module that is executed every time a polygone is
found that contains overlapping, which moves one of the nodes a little, but
this will take time to program.
Does anyone know a way to solve my problem ? ,maybee a MI built in function
that I have missed or maybe someone has already programmed the tool I am
looking for and is willing to share it ?
Best regards
Johann I Dali
