objID = css()
drdGetAllowedWidth(objID "M2" ?constraintGroup "foundry" ?upperLimit 0.05 )
=> (32 37 42 47)

Returns width values less than 0.05 for layer M2.

drdGetAllowedWidth(objID "M2" ?constraintGroup "foundry" ?direction "vertical" ?upperLimit 0.1 )

=> ( 32 37 42 47 52
     57 62 67 72 77
     82 87 92 97
