How can I draw an ellipse whith several or its points at sonme small vertical distance form the ellipse's work plane?
I am not certain I understand your question.
You can only draw on a work plane. Just like you can only put pencil on paper. You can't make pencil write a small vertical distance above the paper.
Now, some elements can be offset from their origin. But otherwise you're going to need to make a new work plane where you want to draw.

Please provide more information. Are you taking about the elipse that results from sectioning a cylinder by a slanted plane?
If I understand correctly I assume gergon44 is talking about an ellipse bend in 3D space.
Something like this example?

Please mention Revit version, especially when uploading Revit files.
