Tracing an ellipse from major axis and given points

[wim (Wim Dekeyser)]

Hi -

@charlycharly

[…] could someone know how to trace an ellipse passing through those points?

That’s not a trivial task to solve.

The following thread has 2 Grasshopper graphs that might get you further:

Fit points to ellipse

Hi, Is there any .Net or Rhinocommon method that approximates an ellipse from a set of points? Similarly to fit circle from points, but for ellipse? I tried to search in google queries but what I found was based on C++ with additional dependencies. Maybe someone have already had this issue?

Also, we have the “Fit ellipse through points function” feature request on the list as RH-62823.
