Terrain not visible/existent in elevation view

[michaelgia 12]

I know this has been posted before but I can't find it anywhere. 

 

I have a terrain in plan for sure because I see it in plan and when I click on it, and open it, the terrain dbx opens up. 

However, in the layer set there is no "Red Cross" in the "used" column. 

 

As a result I can't see the terrain in elevation views. 

 

I feel really dumb, because I'm sure this is elementary. 

 

(Terrain is drawn on first floor)

Ha ha. Nevermind. 

I had put the terrain on the "cad, site plan" layer. 

 

So dumb. 

Wow, one hour wasted.
