Export STL files for import to Maya

Hello!

Would anyone happen to know the proper method of exporting an STL file from Solidworks and importing into Maya?

The issue I am having is when I import into Maya, the 3D object is combined into one shape. When I separate the model in Maya, it will separate the model polygonal-face by polygonal-face, I need it to be in parts. Like the assembly. 

Any help would be wonderful
