The only way is if it is scripted into the object.
You could edit the 3D script using the ROTX command
eg ROTx number_of_degrees
most likely at start of script
The other option is to use a more generic shape the has been already scripted to do what you want, or make your own!!!
Something like that is a great way to start GDL experience
look in manual under BLOCK command and ROT commands
in the 2D script the simplest thing is to use the PROJECT2 command
