How Can I Display Two Components Differently in a Single Drawing View?

[twimer]

I do quite a bit of work designing cast parts and the subsequently machined versions of those castings. Both parts are always shown on separate drawings, but when creating the machined part drawing, it is generally extremely helpful to the machinists if I include a reference line of the cast part. The way I currently achieve this is by putting both components (the casting and the machined casting) into the drawing and putting them on different layers. I will set up the desired view of the machined part, then turn on the layer with the cast part, activate sketch in that view, do a "project curve" where I select just the outside border of the cast part and create sketch lines, then turn of the cast part layer in that view. This works fine except that if I change the cast part, I have to remember to manually update that line in the machined drawing.

Is there a way that I could just keep both layers visible and display the two different parts differently?

Attached is a snippet of the effect I'm looking for (sorry it's small, can't show more than that because it's proprietary, but I think you get the idea).

Hi Twimer,
You can show the view in a shaded mode (STYLE/SHADING/RENDERING STYLE=FULLY SHADED).That way you can apply translucancy to one component and compare the two components easily.
But in case shading is not your choice then there is one more workaround.
Supposingly there are two components in your assembly structure (first one the raw part and second the machined one).Now go to the drafting ...hide one component from assembly navigator and apply a PMI note (let us say REF) to all the edges of the second component (single node but referencing all the needed edges) that you want to display even after the hidden component is brought back.
Now make the hidden component visible again and go to the VIEW STYLE and in the HIDDEN LINE tab turn on the HIDDEN LINE (any line format except invisible) and turn on the REFERENCED EDGES ONLY option just below it.This way the view will show you the complete model along with some of the invisble ref edges for comparison.
You can make the note invisible if you want to.
I am not sure if this will help but as of now this is the only option i am aware of (besides the Shading option).
