You would have to create an ALTERNATE POSITION VIEW in your assembly drawing. You need to create a configuration within your assembly model that would have only those parts visible that you want to create the phantom parts in your drawing. I normally call that configuration ALT POS VIEW but you can call it whatever you would need to. Then in your assembly drawing view you create an ALT POS VIEW & select the configuration that you created for it. The one drawback to this is if you have a BREAK OUT section in that view, then Solidworks will not allow you to create an ALTERNATE POSITION VIEW in that drawing view for whatever dumb reason.
One way would to create Display States that capture the look you need, where the components in the background could be a different color, which you could pick a color that would almost blend in with the drawing sheet color......
In a drawing view, RMB select a component and choose Component Line Font.
Using the Component Line Font dialog, uncheck "Use document defaults"
Next, select the drop down menu for "Visible Edges" and set to phantom.
As far as visibility of item underneath, set the view to HLV.
Software has worked like this for some time.
Thank you John.
Ed, Component line font works to make the affected part show in phantom linetype but wherever an other wise visible line passes under the phantom part it shows as a hidden line.
Thank you all for your help.
