Call model from another model

Hey Guys I want to call model from another model. Actually I need data from model2 to model3.

Can you tell me how to call model2 from model3?

Just like you would anywhere else:

// Model 3

public function useModel2()




    // play with data here <img src='' class='bbc_emoticon' alt=':)' />


Thanx :rolleyes: :rolleyes:
