Show part as outline without hiding parts behind

Hi guys,

I'm drawing up a Gas Tank Stand we are making and I want to show a dashed line outline of the gas tank in position without hiding any detail from the stand itself.

On the left shows the assembly in its entirety, on the right shows what I want. I did this by selecting all the edges of the gas tank and using convert entity then hiding the tank. This is quite time consuming and so was wondering if there was a way to display selected parts like this or similar.

Thanks in advance for any help you can give.

Cheers,

Steve
