Blocks disappear in render after a zoom in

Hello

I am working on a 3D model using 3D solids and 3D blocks, then I make a render of a view and works fine, but if I make a zoom in to a zone and render it then the 3D blocks disappear showing only the floor (a 3D solid) and sometimes the render is just plain black, after a zoom out everything works fine. I made an Audit, exploded the blocks, even when making a crop render, no luck. Attached images explain better, I hope.

TIA and regards!
