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);
