Charbini Welcome to the forum! 🙂
The export should conform to SVG 1.0 or 1.1 and specific settings are not required, but you should ensure a proper scaling: StitchBuddy will interpret every unit - independent of the actual measurement unit - as 1/10 millimeter. So a graphic of 1,000 pixels square (or points, inches, meters) will result in a shape 10 cm x 10 cm (or roughly 4“ x 4“).
Depending on the source programm, importing SVGs might require the „import only stroked paths“ setting being deactivated in the „Open“ dialog. Please refer to this FAQ article to learn the reasoning behind and why there is no optimal default setting.
I hope you don’t mind me moving this discussion into the „Tips & Tricks“ category…
