Spiral-ramp in a perforated ellipsoid


New member
Can anybody help me figure out how to exactly model a spiraling ramp with level platforms at regular intervals into a tilted ellipsoid?

The only way I came up with so far would be to draw the ramp and platforms in 2D and then to map or wrap this around the ellipsoid. Only I don't know how to do that, flowalongsrf doesn't seem to work for that.

I also want to perforate the shell of the ellipsoid with a circle pattern. flowalongsrf works but distorts the pattern towards the two ends of the ellipsoid. Is there a way to distribute this circle pattern evenly around the surface?

Thanks for your help!
