How do I search Symbols by name?

Rian

Our diagrams should have certain "mechanical" symbols but Ravel does not have a "symbol" built-in relation. I know it has a shape relation but this does not have a component_name?

I guess the easy question is how do I find this iron man fiducial?...

Here's the code that fails:

(define FiducialIM
    (select (mSymbol) shape  ; NO symbols relation :(      
        component_name?(mSymbol, "IRON_MAN_BOC")
    )
)

P.S. I am told by the designers we can't make these symbols components because they are mechanical only.

    This returns nothing though:

    (define FiducialIM
        (select (mSymbol) component
            mechanical?(mSymbol)
        )
    )

    (report (mSymbol) FiducialIM
     ("All Components ~A" mSymbol, boundary(mSymbol))
    )

    In fact if I report all component (I just replace mechanical? above with 1==1 :) I get a whooping 1:

    All Components #<symbol:DIE> (((3120.5 4340.0) (-3369.5 4340.0)) ((3120.5 -3340.0) (3120.5 4340.0)) ((-3369.5 4340.0) (-3369.5 -3340.0)) ((-3369.5 -3340.0) (3120.5 -3340.0)))

    Here's another image from Cadence if it helps...
