@Marcel_Rijsmus hope it might be okay to ask about this on this thread, if not I will delete - I wanted to produce a Mobius Strip and have found some strange results; I’m wondering if someone more mathematically inclined than me might have an explanation?

A Möbius strip of half-width w with midcircle of radius R and at height z=0 can be represented parametrically by

x = [R+

scos(1/2t)] cost

y = [R+scos(1/2t)] sint

z =ssin(1/2t)

Image and formula from: http://mathworld.wolfram.com/MoebiusStrip.html

This is the result in Dynamo:

DesignScript (using number sliders for s and r):

```
s = -n..n..0.001;
t = 1..10000;
x = (r + (s * Math.Cos(t/2))) * Math.Cos(t);
y = (r + (s * Math.Cos(t/2))) * Math.Sin(t);
z = s * Math.Sin(t/2);
points = Autodesk.Point.ByCoordinates(x,y,z);
Mobius = Autodesk.PolyCurve.ByPoints(points);
```

Any ideas? I know that its meant to be a surface and I am generating points/polycurves so might be the explanation, but I suppose I wasn’t too sure how to generate it otherwise
