Assura DRC: How to Define derived layers

stuso

Hi there,

I'm wondering how you define your own variables/derived layers, e.g when i'm using this
command:

    newVia2_a = geomSize( VIA2 0.07 )

However Assura doesn't seem to like that i have not deifined "newVia2_a".

Can someone tell me the syntax to do this, i'm assuming it has to go in the  layerDefs section somehow.

Thanks

Stu

    Hi Lawrence, 

    can you(or anyone out there) please ask the Assura guys if you cannot perform geomAnd on derived layers, so for example this would not work:

     drcExtractRules(

    layerDefs( "df2"

          OD          = layer( "OD" )

    ); end df2 layerDefs

        OD_1         = geomSize( OD 0.005 )
        OD_2        = geomAnd( OD_1 )
        saveDerived( OD_2 "TESTING OD_2 ")

    )

    This fails with:

     error:  No such original or unmerged layer 'OD_1'.

    When  i change the geomAnd to geomOr the code compiles (though of course its not what i want functionally).

    I read in the assura manual regarding geomAnd:

    " Description
    Generates new shapes from the overlap of original shapes on the input layers."

    So this perhaps infers that you indeed cannot geomAnd derived shapes?

    Cheers
