[ODE] Complex Body Creation

[achaudhry]

hi, 
I am trying to create a single object which comprises of 4 boxes attached in a
fixed manner. 
to create this complex object, i am currently creating seperate boxes and then
attaching them using Fixed joints. Is there any other method of creating this
complex object? 

Also after creation, for changing the orientation etc of the complez ogject, i
have to currently change orientation for all individual boxes, is there a way
to group these boxes together as one single object and then perform operations
on them as a single entity? 

Regards, 
Amber
