Detail View?

I want to change the appearance of a detail view, but I do not know how to go about it and I am hoping some kind soul will point me in the right direction. In the image below you can see the detail view I have currently. Where I have marked the image I would like to change this line so it is easier to see that it is broken off the main body. A sort of jagged line so it will not be easily confused with a machined type surface. Is this possible?
