Using version 2012, SP5, x64 edition.

I want to show only some of the hidden lines in a complicated part so I am manually Hiding lines. 

In the Isometric view I want to remove only the hidden portion of a visible edge, not the portion that would be visible.  (see the circled areas)

Solidworks doesn't seem to be able to do this even though Exporting the Solidworks drawing to AutoCad shows the Hidden line and a Visible line, making removing that unwanted Hidden segment possible.

Am I missing something that would make it possible to remove the unwanted section of these edges?

Thanks,

Elena
