Every time I create an BSP object it goes entire black !
I don’t know why it is not showing the “grids and transparent white aspect”
This is how its supposed to be:

I assume because you have no lighting in your scene 
Add a BP_skysphere and a directional light to use with its settings. Or at a minium a point light to light upy our scene.
Hope this helps
