I am a fustrated peanut.

Hello all!

I am new to Nomad. I am trying to learn how to make Pasties for burlesque dancing. All I really need is how to make a 2D shape like a heart or a fish or a simple circle , rounded. I have scoured the internet looking for a tutorial and whilst I have managed to make a round pastie by chopping a sphere , but It prints horribly. Can anyone help or point me into the right direction please ? Many thanks!
