Functionality

• Provides comprehensive document import and export with 35+ supported file formats. This allows developers to convert documents from one file format to another. For example, you can convert DXF to DWG and DWG to DXF documents with professional quality.
• Contains a flexible mechanism for working with files, namely: reading, updating and writing, and also provides the ability to create CAD files separately.
• Provides the ability to work with text, extract all text from an drawing or adjust it by changing position, size and visibility, as well as work with fonts separately
• Provides a flexible variety of capabilities, such as adjusting drawing element line lengths, exporting these components to multiple PNG files, removing certain entities and easily editing a large number of distinct entities and more.. Thanks to its extensive toolkit, users may precisely and customise their images and designs.
• Provides the ability to work with 3D files, including change the observation point and supports mtl files when exporting files to OBJ format.
• Provides the ability to insert DXF/DWG drawings into DWG/DXF.

Getting Started with Aspose.CAD for .NET

Are you ready to give Aspose.CAD for .NET a try? Simply execute Install-Package Aspose.CAD from Package Manager Console in Visual Studio to fetch the NuGet package. If you already have Aspose.CAD for .NET and want to upgrade the version, please execute Update-Package Aspose.CAD to get the latest version.

Add Watermark to CAD using C# Code

You can execute below code snippet to see how the API performs in your environment or check the GitHub Repository for other common usage scenarios.

CadText text = new CadText();
text.DefaultValue = "Watermark text";
text.TextHeight = 40;
text.FirstAlignment = new Cad3DPoint(300, 40);

Export of DWG to PDF with drawing color change using C#

Image img = Image.Load("Drawing.dwg");
MemoryStream ms = new MemoryStream();

var rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 500;
rasterizationOptions.PageHeight = 500;
rasterizationOptions.Layouts = new string[] { "Model" };
rasterizationOptions.DrawColor = Color.Red;

var pdfOptions = new PdfOptions();
pdfOptions.VectorRasterizationOptions = rasterizationOptions;

img.Save("output.pdf", pdfOptions);

Generate DXF drawing from scratch and its conversion to PNG using C#

DxfImage img = new DxfImage();

CadLine line = new CadLine(new Cad3DPoint(0, 0, 0), new Cad3DPoint(100, 100, 100));
img.AddEntity(line);

CadText text = new CadText();
text.FirstAlignment = new Cad3DPoint(0, -50, 0);
text.TextHeight = 10;
text.DefaultValue = "text value";
img.AddEntity(circle);

CadCircle circle = new CadCircle(new Cad3DPoint(50, 0), 10);
img.AddEntity(circle);

var rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 256;
rasterizationOptions.PageHeight = 256;

var pngOptions = new PngOptions();
pngOptions.VectorRasterizationOptions = rasterizationOptions;

img.Save(ms, pngOptions);
