How can I model a butterfly knot on inventor

Hello,

I want to study the bearing capabilities of a butterfly knot and a double eight knot, since it's a complicated geometry i'm not able to model it. I will appreciate any help.

I suggest making several points to guide a 3d curve on it. Use a plane sketch for few points on top view, than make a few offset layers to project the relevant points onto them to make it 3d. connect lines and curves or 3d spline on the points.
A simple sweep with a circle will make the knot.
