Line Trace to Crosshair Third person

I have used Hud to create a crosshair in the middle of the can i set a line trace from midlle of body(i got that part working) towards the crosshair?It has to bee done in third person

use camera location as start trace and camera rotation as direction

and end trace would be start trace + direction * trace range

it will aim right at crosshair

take a look at this
