Support inside models infill

[wiseby 0]

I have a problem that keeps haunting me. I want to print support inside model for flat surfaces. Otherwise it would print in mid air.

Or make it as a bridge but I cant figure it out. I thought that this would be recognized as a bridge?

 

I would prefer to print a solid layer over the entire model before top surfaces inside the model.

 

Curious why I couldnt find this issue on the internet. Am I doing somthing wrong?!

One solution would be to use modifiers to create support where it is needed.

How do I accomplish that?
