Ahhaaa, I stand corrected, assumptions is never ever good and it should have been obvious when making the thickness large, e.g if as large as the short axis it would generate a inner 'not ellipse' with short axis equal to 0. Sorry for my noise, I only did some simple checks with small thickness and did not go all the way. > If this error is small enougth to ignore, fine, but what error do we > tolerate? > > Regards, > /Karl Hammar > > [1] > http://de.wikipedia.org/wiki/Ellipse#Normalengleichung_.28kartesische_Koordinaten.29 > > ----------------------------------------------------------------------- > Aspö Data > Lilla Aspö 148 > S-742 94 Östhammar > Sweden > +46 173 140 57 > > > > > _______________________________________________ > geda-user mailing list > geda-user@moria.seul.org > http://www.seul.org/cgi-bin/mailman/listinfo/geda-user > _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
