op van maximaal 1000 iteraties
3) Offset de polyline en maak een nieuwe Brep van alle curven
4) Bepaal de Area-centroid van de Brep
5) Bepaal het verschil tussen de huidige centroid en de gezochte centroid
6) Als dit verschil minder is dan 1e-12 breken we af
7) Vermenigvuldig het verschil met vier en pas de polyline aan
8) herhaal (3 - 7)
Is dit min of meer wat je wilde? Het lijkt dat er ~50 iteraties nodig zijn voor een antwoord dat accuraat is binnen de 1e-12 eenheden.

when i type the equations for z,y,z it says a syntax error so i obviously do not understand how to construct an expression. (screen capture attached)
Any help/explanation of using this function would be greatly appreciated
thanks so much

generations of 50 individuals) of the same model that I got NaN's on before. As far as I can tell, it shouldn't be a division by zero problem, I'm solving the following formula: (a/10*b)-(c*d)-(e*f)-(g*h). I did save the text outcome of the run but I'm not sure which gene is what so I'm not sure how to recreate the exact situation... Is there something you want me to try?
BTW, what is a collision?
cheers,

dont get you, i am saying sleect numbers in range 1 to 10, starting from 1 with a step of 2.
1 to 10 by 3 = 1 4 7 10
1 to 10 by 5 = 1 6
1 to 10 by 1 = 1 to 10 = 1 2 3 4 5 6 7 8 9 10

te one of the boxes (kind of). Now I'm trying to set up the pattern, but I would like it to be random. I'm having trouble coming up with the actual algorithm, though.
I'm able to generate a list of items, randomly select some of them, and rotate them. I can also select the item after a rotated one and move it to the right.
However, I'm having trouble selecting all of the items after an item that's been rotated, and moving all of them.
Let's say I have a list of 15 elements and numbers 3, 6, and 7 are rotated. I would need to move numbers 4 through 14 (since it starts at 0) to the right by an x amount; numbers 7 through 14 to the right by a 2x amount; and numbers 8 through 14 by a 3x amount.
How should I go about doing this?
I'll add my current non-working setup. I should note that since I'm new, it probably looks horribly disorganized. Sorry about that.
Thanks!…
