How can I modify the position (rotate, move) of an imported geometry?

In order to change the position of the imported geometry, you have to use the following method:

1	Create 2 coordinate systems as follows : A in [0,0,0] with respect to XYZ1 B in [0,0,0] with respect to A
2	Import the geometry and center it to B
3	Modify the rotation angles (about X,Y or Z) of the system B in order to rotate the geometry as needed
4	Modify the origin (X, Y or Z) of the system A in order to move the geometry as needed
