Refine Line/Curve Quality of SVG Vector Output from Rhino

Hi - I’m using the ‘Make 2D’ command and exporting my Rhino line-art as SVG. When importing into Affinity Designer the SVG line-art is faceted, does not come in as as smooth bezier curve.

Is there a setting in Rhino where I can adjust the quality of the exported svg line-art?

I ditched Adobe Illustrator a while ago so I do not have that option available to me.
Exporting as a PDF gives me the same results when opening in Affinity Designer.

Thanks for any advice.
