Help with Block with Multiple Line Types

I have created a block (a hydraulic symbol) with multipleline types and when I insert it into a drawing the line typesswitch to the default of the new drawing. i.e. all the dashed lineschange to solid lines. Does anyone know of a way to preserve linetypes in blocks or a place where I can purchase hydraulic symbolsfor Solidworks?

Thanks!SolidworksDrawings And Detailing
