How to undo the effect of a Display3 on a body

Hi everyone,

I have the need to check all the components in an assembly to determine is an external files (other data) exists for the part.

My preference is to use a visual way to signal that a part is missing this data (and it can be created within SW).

I can do the traverser and find the 'offending parts' and I can use the body.display3 method to highlight ....   but how do I turn the display off?  I need to be able to clear it like the other display function that offer a true/false option.

Thanks in advance !!
