Hello Pascal,

TsgPDFExport.PageHeight and TsgPDFExport.PageWidth are measured in millimeters, the default values are 297 mm and 210 mm, respectively. The page orientation can't be set explicitly, you should specify PageWidth and PageHeight instead.

TsgDXFBlock.AddEntity returns a number of entities in the block.

Hello

" you should specify PageWidth and PageHeight instead. "

Problem: this property in read only:

TsgPDFExport = class(TsgSimpleExport)
private
FData: TpdfStrings;
.../...
property PageWidth: Double read FPageWidth;

==> READ ONLY ??
solution ??

Thanks / Pascal

Hello Pascal,

The PDF export parameters are set using the TsgPDFExport.ApplyParams procedure:

Code: Select all

procedure SaveToPDF(ACADImage: TsgCADImage; AFileName: string);
var
  vPDFExport: TsgPDFExport;
  vExportParams: TsgExportParams;
begin
  if not Assigned(ACADImage) then Exit;
  vPDFExport := TsgPDFExport.Create(ACADImage);
  try
    vExportParams := DefExportParams;
    vExportParams.PageWidth := 297;
    vExportParams.PageHeight := 210;
    vPDFExport.ApplyParams(vExportParams);
    vPDFExport.SaveToFile(AFileName);
  finally
    vPDFExport.Free;
  end;
end;
