[Noob - looking for simple explanation - What is skin ?]

Wow @GregValiant THANKS for that thorough explanation.

 

You're saying that the layers printed on the bottom and top of the model, excluding the inner and outer walls are the skin (am I correct ?). I'm still confused though, under the shell category there is no way to set number  or thickness of skin (just top surface skin layers), but I can change Top\Bottom thickness. I'm concluding that there are  Top\Bottom layers (adjustable thickness ) and skin layers (non adjustable thickness), my question is what is the difference  or relationship between Top\Bottom and skin ?

I searched and read all I can find, but i'm still not sure what skin is ? where do I see it ? what dose it do ? do I even need it ?

 

 

Thankyou
