At my company most of our products come insulated and clad in sheet-metal. For the drawings I want to be able to show the main product as if the insulation wasn't there (ie. solid lines) but with the outline of the insulation shown as dashed lines which i can dimension.
I made the attached image to help explain. The left shows the main product with out the insulation which is exactly what I want that part to look like then the right I set to wire-frame and set the insulation line style to dashed.
So I kind of need to "hide the insulation" but show it as "hidden" even though its the part in front of the rest if that makes sense.
Thanks in advance.
