How do I import a custom cutout object?

pardon - what do you mean - is this a 3D object or a 2D object ? is it geometry or is it a mask or silhouette in which case any of the import file extensions should work ? it would help if this was more descriptive - thanks.

(this is the old UI but the process should be pretty much the same)

Thanks a lot for the support.
