I am trying to design this swirly installation that would hypothetically be hung on the ceiling with a grid. Each point of hanging would be 500mm apart. (See attached picture) The problem is, when I divide the curve in equal 500mm length, the point doesn’t align with the intersection point of the grid. So, I was wondering how to achieve both:

- Have the points exactly (or very close to) 500mm apart;
- Have the points align exactly with the intersection point of the grid.

Any insight/clue will be very helpful! Thanks very much in advance
