It looks like Draft point array doesn't currently work with the Points object. Here is a macro I threw together to convert the Points object into a compound of Draft.points, which will work with the Draft point array. Select the Points object and run the macro. It will take a while depending on how many points you have. Look at the status bar to see a progress indicator.

... just for fun I also tried to position spheres on a moebius tape via PathArray.

Great! a such macro is missing in Point Wb. Should be added to.
