Manually segmenting things with paint brush and erase brush.

Problem?

Do I really have to paint a simple structure?  
Is there no way to \>\>\> just paint the outlines and then \>\>\> fill (BUT ONLY THAT SLICE IN 2D)

I post an image to explain it all

What you describe is called “Draw” effect in the Segment Editor.

I feel soo ashamed… I didn’t realize that. I clicked on draw and I was wondering why was I getting those simple lines.

I am so ashamed… The first thing I asked on this forum was little bit tricky but this was waaay too simple not to figure it out on my own. I am so ashamed
