The fastest and efficient way to make this bow

Hi Rhino experts!

I am having trouble to find an easy and fast way to remake the bow which needs to look exactly the same like the file I attached.

Please help, thanks!

You got the file already obviously so I’m guessing you’re looking for opinions on how to model it from scratch.

I’d use Sweep1 with multiple deformable ellipse cross sections and History enabled. This will get you the main loops with open ends. Edit the position of the cross sections and the central sweep rail to tie the knot or make the appearance of a knot. Finally, use SplitEdge to separate the open end edge into two parts. Use BlendSrf to make the domed cap at the end and Join the result.
