Thank you for everyone!
First, I have tried the advice from Daid.
The way of extruding material, path(red lines in Cura), is exactly what I was looking for. But I met two additional issues with the way .
1. How to control the thickness of printed shell with using the option of Only follow mesh surface in Black Magic?
When the shell is printed with option of Only follow mesh surface, one layer is completed with only one extruding path.
2. Is it impossible to print inside surfaces?
Inside surfaces cannot be recognized in Layers View Mode and cannot be sliced as below images.

Second, I have a question with gr5's advice.
1. Does the inner walls which you mentioned mean the surfaces which cannot be recognized in Cura which was mentioned in my above question?
>If you want inner walls and not just outer walls you might have to make the walls .81mm thick (not .41) to get Cura to slice it.
If so,
I tried to make the walls .81mm. But there is no change in recognizing and slicing the inner walls in Cura.
Could you please let me know what I have to do in next step?
Third, I have tried thicken the surface for solid geometry which was advised from Solid Print 3D.
But at present, I am suspending the way, because there is the part which go wrong when it is thickened.
Thank you again,
Tae
