Gets or sets which drawing spaces are converted. Defaults to Both, which does not restrict the conversion. It is ignored when LayoutNames is supplied, because explicit layout names always win. A null value is treated as Both.
publicCadLayoutScopeLayoutScope{get;set;}
Remarks
A scope that selects none of the sheets a drawing offers fails the conversion with an InvalidLoadOptionsException naming the scope and the sheets that are there, rather than rendering the spaces the scope excluded. A drawing that offers no sheet at all is unaffected and still converts as a single unit. Not honoured when converting to PDF/UA-1, for the reason given on LayoutNames.
