How to draw an elliptical line?

Hello,

I would like to create a line that simulates the elliptical orbits of the planets specifying the two focuses of the figure. The line must follow the elliptic math function. How can I do this? I have searched a lot on the web but I have found nothing that fits my problem. Any help is appreciated

Okay maybe I have found a solution by myself :grinning:. I think beam particle system is the way, I hope I can control tangents from blueprint
