Hi Matadem, or maybe something like this - draw a polyline like this:





Draw a circle and use Cosntruct > Sweep to sweep it on the polylline:



Put in a sphere at the top:

Got it! looked at the freecad tutorial in Moi sweep Circle with a rail and a scaling rail to adjust the size in the end ...took seconds lol.

I did not know you could sweep with the circles not on the rail...even faster :D
I was wasting my time aligning them.

Tnx!
