Java API to Create, Edit & Convert CAD Drawings

It enables software developers to convert AutoCAD DWG, DXF & STL Documents to PDF & Raster Images (BMP, GIF, JPG & JPEG) without any dependencies.

Aspose.CAD for Java is a flexible Java library gives software developers the power to open, read, render, manipulate and convert AutoCAD DWG, STL, DWF, DWT and DXF Documents to PDF & Raster Images without requiring AutoCAD or any other CAD software. The library provides an easy-to-use API that fully supports working with CAD files programmatically and integrates them seamlessly into your Java applications. The library is designed to be thread-safe, which means that users can use it in multithreaded environments without worrying about concurrency issues.

Aspose.CAD for Java has included a very useful feature for converting CAD drawing formats such as DXF, DWG, DWT, DGN, IFC, DWF, DWFX, STL, IGES(IGS), CF2, Collada(DAE), PLT, OBJ, SVG, DXB, FBX, U3D, 3DS, STP files to PDF as well as the supported raster image formats such as PNG, BMP, TIFF, JPEG & GIF with just a couple of lines of Java code. Aspose.CAD for Java is very easy to handle and designed to be fast and efficient, with a small memory footprint and optimized performance. The library uses advanced algorithms to ensure that operations on CAD files are fast and responsive.

Aspose.CAD for Java has included some advanced features, such as rendering and printing CAD files inside Java applications. One of the most powerful features of Aspose.CAD is its ability to manipulate and convert CAD files. Software developers can utilize the library to create, edit, and delete CAD objects such as lines, circles, arcs, and text. It is also possible to modify object properties such as color, layer, and linetype. Aspose.CAD for Java provides full support for 3D models and allows you to work with them in the same way as 2D models. Overall, it is an spontaneous Java API supporting advanced features, and excellent customer support making it an ideal choice for Java developers who need to work with CAD files inside their applications.

Export CAD Files via Java API

Aspose.CAD for Java enables software developers to convert various AutoCAD formats to other support file formats with just a couple of lines of Java code. The library allows loading various CAD file formats such as DXF & DWG and converts it to PDF and raster images without needing AutoCAD or any other application. The library has provided several important functions for CAD files conversion, such as export 3D AutoCAD images to PDF, export CAD layouts to PDF, set pen properties options while exporting diagram, decompose cad objects and process separate entities inside insert, ACAD Proxy Entities, read and export IGES format, implement and count mesh models like edges, vertices and faces, set custom point of view for Model layout and many more.

Export 3D AutoCAD Images to PDF via Java API

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);

Render CAD & BIM File Formats via Java API

Aspose.CAD for Java gives software developers the ability to programmatically render CAD and BIM file formats inside their own Java applications. The library allows loading various CAD file formats such as AutoCAD DWG, DWF, DWT or DXF files and convert it to JPEG, PNG, PSD, BMP, DICOM, WebP, EMF, WMF, SVG, PDF and many more with just a couple of lines of Java code. The below example demonstrates how to load DWG file, set the page width and height of the output file and save DWG files to PDF inside Java applications.

Render DWG files via Java API

// Load the CAD file
Image image = Image.load("input.dwg");

// Create an instance of CadRasterizationOptions
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setPageWidth(1000);
rasterizationOptions.setPageHeight(1000);

// Set the render options
PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

// Save the output file
image.save("output.pdf", pdfOptions);

Export AutoCAD DGN to PDF via Java API

Aspose.CAD for Java is a powerful API that allows software developers to work with AutoCAD DGN files inside their own Java applications. The library supports AutoCAD DGN files conversion to PDF as well as raster Image file formats such as PNG, BMP, TIFF, JPEG and GIF with ease. To achieve the goal first you need to load an existing DGN file as DgnImage and set different properties for it, after that Call the save method of the DgnImage class object to save the output file in the format of your choice.

Convert AutoCAD DGN Format to PDF via Java API

// load an existing DGN file as DgnImage.
DgnImage dgnImage = (DgnImage)Image.load(dataDir + "Nikon_D90_Camera.dgn");
// Create an object of CadRasterizationOptions class and define/set different properties
PdfOptions options = new PdfOptions();
CadRasterizationOptions vectorOptions = new CadRasterizationOptions();
vectorOptions.setPageWidth(1500);
vectorOptions.setPageHeight(1500);
vectorOptions.setNoScaling(true);
vectorOptions.setAutomaticLayoutsScaling(false);
options.setVectorRasterizationOptions(vectorOptions);
OutputStream outStream = new FileOutputStream(dataDir + "ExportDGNToPdf_Out.pdf");
// Call the save method of the DgnImage class object.
dgnImage.save(outStream, options);
