How do i create a doodad of the orc fortress?

I tried making a doodad with the "greathall,stronghold,fortress" model, but when i place the doodad i can only place a greathall, how do i get around this?

Maby you can make three doodads with the different models.

you can only select the model "greathall,stronghold,fortress", theyr all one model

Just take a look at the map itself.

the fortess in that map is a unit, not a doodad

I thought you where asking about the orc fortress in the campaign, not a unit itself. Why dont you just want to use a normal unit?

IM trying to build an orc city, so i need to be able to rais and lower it, as well as place in half in other doodads

Check required animation names. Try
upgrade
second

I tried basing it off support collum and Ruined Trash and it worked fine. If it's just a cinima, create a new unit and make the model to the fortress or what ever and set height to what ever you want.
