Exportando CAD

Exportar imágenes 3D de AutoCAD a PDF

Aspose.CAD te permite exportar imágenes 3D de AutoCAD a PDF. Por favor, utiliza TypeOfEntities.Entities3D en ImageOptions.CadRasterizationOptions para especificar que deseas exportar entidades en 3D. El siguiente código de ejemplo carga un archivo 3D de AutoCAD y lo exporta a PDF. Una vez que el archivo se convierte a PDF, puedes abrirlo utilizando tu visor de PDF favorito.

El siguiente código de muestra muestra cómo exportar imágenes 3D de AutoCAD a PDF.

// For complete examples and data files, please go to https://github.com/aspose-cad/Aspose.CAD-for-Java
// The path to the resource directory.
String dataDir = Utils.getDataDir(Export3DAutoCADImagesToPDF.class) + "ExportingCAD/";
String srcFile = dataDir + "conic_pyramid.dxf";
		
Image cadImage = Image.load(srcFile);

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setPageWidth(500);
rasterizationOptions.setPageHeight(500);
rasterizationOptions.setTypeOfEntities(TypeOfEntities.Entities3D);
rasterizationOptions.setLayouts(new String[] {"Model"});

PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

cadImage.save(dataDir + "Export3DImagestoPDF_out_.pdf", pdfOptions);

Exportar diseños de CAD a PDF

Aspose.CAD para Java te permite exportar diseños de CAD a PDF. El método save de la clase CadImage se puede utilizar para exportar el(los) diseño(s) a formato PDF. El siguiente código de ejemplo carga un archivo CAD y exporta su diseño “Modelo” a PDF. Una vez que el archivo se convierte a PDF, puedes abrirlo utilizando tu visor de PDF favorito.

Aquí está el código de ejemplo.

// For complete examples and data files, please go to https://github.com/aspose-cad/Aspose.CAD-for-Java
// The path to the resource directory.
String dataDir = Utils.getDataDir(ExportCADLayoutsToPDF.class) + "ExportingCAD/";
String srcFile = dataDir + "conic_pyramid.dxf";
		
// Create an instance of CadImage class and load the file.
Image cadImage = Image.load(srcFile);

// Create an instance of CadRasterizationOptions class
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setPageWidth(1600);
rasterizationOptions.setPageHeight(1600);

// Set the Entities type property to Entities3D.
rasterizationOptions.setTypeOfEntities(TypeOfEntities.Entities3D);

rasterizationOptions.setScaleMethod(ScaleType.GrowToFit);
rasterizationOptions.setContentAsBitmap(true);

// Set Layouts
rasterizationOptions.setLayouts(new String[] {"Model"});

// Create an instance of PDF options class
PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

// Set Graphics options
rasterizationOptions.getGraphicsOptions().setSmoothingMode(SmoothingMode.HighQuality);
rasterizationOptions.getGraphicsOptions().setTextRenderingHint(TextRenderingHint.AntiAliasGridFit);
rasterizationOptions.getGraphicsOptions().setInterpolationMode(InterpolationMode.HighQualityBicubic);

// Export to PDF by calling the Save method
cadImage.save(dataDir + "CADLayoutsToPDF_out_.pdf", pdfOptions);
