Hi,

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

Hope this is what you are looking for.

(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.
