BL Scening Can you fill in the bottom of models if you want to elevate them?

[nsg3]

As you an see from the pictures I'm attempting to create a massive fountain.
Simply elevating a fountain on some pillars.
From the top it looks fine, but if you look from below clipping kicks in.

Is there anyway to show the bottom? I've been clicking around everywhere and can't figure it out.

It likely doesn't have a bottom on it at all, as it's normally meant to be in the ground (therefore normally you'd never see the bottom, so they'd not include it in the model).

I'd suggest duplicating, turning it upside down, and covering up the water with a flat piece of geometry.

Edit : Added missing part of suggestion

Yeah, that's what I did, essentially, I combined two platforms to make a plate instead of the fountain though so I didn't have to worry about the water.

I thought that might be case with the bottom faces.
