Hello Pilou,

I thought also about the problem and I agree with Michael. A simple, but very coarse filter would be to analyse boundingbox aspect ratio and the curve length in relationship to the absolute dimesions of the boundingbox.
And I have to note, the script CCWC isn't my project, it is an example to show the input parameters of the circle-factory in
Mindsets script! So I didn't tested it really.

Have a nice day
Karsten
p.s.: I have tried to implement gestures in MOIs scriptengine and it is a similar, but difficult problem.
