Aspose.CAD for .NET 1.0.0 Release Notes
We are pleased to announce the first release of Aspose.CAD for .NET. It allows you to convert AutoCAD DWG and DXF files to PDF and Raster images. It is a native API and does not require AutoCAD or any other software to be installed.
You can also convert the selected layers and layouts from the AutoCAD files. The conversion to PDF and Raster images is of very high quality. At the moment we support the following Cad image types for loading (please refer to the https://autodesk.blogs.com/between_the_lines/autocad-release-history.html DWG file history): o CadR11 o CadR13 o CadR14 o CadR2000 o CadR2004 o CadR2010 o CadR2013

Public API and Backward Incompatible Changes
Please note that Aspose.CAD API was split from Aspose.Imaging API, hence its public API is almost the same so you can easily migrate to Aspose.CAD by renaming the namespaces to Aspose.CAD instead of Aspose.Imaging. Following is an example to convert CAD documents to PDF using Aspose.Imaging and Aspose.CAD respectively. You can notice that just Aspose.Imaging namespace has been replaced with Aspose.CAD.
Aspose.Imaging Code
string sourceFilePath = myDir + "sample.dxf";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(sourceFilePath))
{
//Create an instance of CadRasterizationOptions and set its various properties
Aspose.Imaging.ImageOptions.CadRasterizationOptions rasterizationOptions = new Aspose.Imaging.ImageOptions.CadRasterizationOptions();
rasterizationOptions.BackgroundColor = Aspose.Imaging.Color.White;
rasterizationOptions.PageWidth = 1600;
rasterizationOptions.PageHeight = 1600;
//Create an instance of PdfOptions
Aspose.Imaging.ImageOptions.PdfOptions pdfOptions = new Aspose.Imaging.ImageOptions.PdfOptions();
//Set the VectorRasterizationOptions property
pdfOptions.VectorRasterizationOptions = rasterizationOptions;
//Export the DXF to PDF
image.Save(myDir + "result.pdf", pdfOptions);
}
Aspose.CAD Code
string MyDir = RunExamples.GetDataDir_ConvertingCAD();
string sourceFilePath = MyDir + "conic_pyramid.dxf";
using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(sourceFilePath))
{
// Create an instance of CadRasterizationOptions and set its various properties
Aspose.CAD.ImageOptions.CadRasterizationOptions rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions();
rasterizationOptions.PageWidth = 1600;
rasterizationOptions.PageHeight = 1600;
rasterizationOptions.BackgroundColor = Aspose.CAD.Color.Beige;
rasterizationOptions.DrawType = Aspose.CAD.FileFormats.Cad.CadDrawTypeMode.UseDrawColor;
rasterizationOptions.DrawColor = Aspose.CAD.Color.Blue;
// Create an instance of PdfOptions
Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
// Set the VectorRasterizationOptions property
pdfOptions.VectorRasterizationOptions = rasterizationOptions;
// Export CAD to PDF
image.Save(MyDir + "result_out_.pdf", pdfOptions);
}
