Hi,

You can find information on how to 'connect attributes' in cga here:

Hope this is what you are looking for.

Floor -->
split(x) {~Tile_Width : Tile}*

attr Tile_side_Width = 1.5

Tile -->
split(x) {Tile_side_Width : Wall | ~1 : Tile_Main | Tile_side_Width : Wall}

attr Window_BaseHeight = 0.9
attr Window_Hegiht = 1.4

Tile_Main -->

texName = fileRandom("window/sash_window_*.jpg")

Window-->

texture(texName)

(I wrote a script like this and I don't know where to fix it.)

Try to connect the object attribute to the model by matching attribute names. Change your attribute name on your code from 'attr Building_Heignt = 20' to 'attr NMLY = 20'.

I believe CE will use the value '20' only if it doesn't get any value from the object's attribute.
