Edit existing parts 3d package

[leslieFRT9A]

Hello,

i have placed a xh 2 pin jst type connector in a schematic and positioned it on the pcb board all as i would like. When i then call up the 3d model of my pcb the xh connector is half embedded in the board surface. I believe this is because the origin of the model was set in the wrong place and the 3d board places the connector origin at the surface of the board.  I would like to fix this by editing the 3d connector package and relocating its origin to the correct surface. 
does anyone know how i can access the 3d connector model in fusion as if i can edit that model the change is easy to make. 
hope someone can advise. 
regards

Go to Package tab and double click on package name.
Or, component you've placed have little caret(arrow). Click on it and you will see connected symbol, footprint and package with component.

Hello SilvioCro and thank you for your help.  I am a little confused as to the following :

Package tab -> not sure what this is as i may just know it as a different name

I have the component placed in the Schematic and on the board and it translates to the 3D board but I am not sure which component location you are reffering to for me to find the caret

Hope you dont mind explaing above for me.

regards
