2D Drafting problem to join two files in one

Hello I need your help please

I have two .prt files in master model

"-2D INSULA OPP-10-01"

(Conteins ITEM #003 & ITEM #030)

(2D data sheet file) 

"-2D INSULA OPP-10-02"

(Conteins ITEM #006,#010,#021,#210,#211)

(2D data sheet file) 

And I have the file:

#INSULA OPP-10 REV-03 180206 

Which conteins the 3D Model

I need to join all items in "-2D INSULA OPP-10-01"

(only one .prt file)
