Adjusting CAD Drawing Size in Aspose.CAD for .NET

Introduction

Are you looking to seamlessly adjust the size of CAD drawings in your .NET applications? Aspose.CAD for .NET provides a robust solution, allowing you to effortlessly handle CAD drawing resizing. In this tutorial, we’ll guide you through the process, breaking down each step to ensure you grasp the intricacies of resizing CAD drawings using Aspose.CAD.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites in place:

• Aspose.CAD for .NET Library: Download and install the library from the Aspose.CAD for .NET download page.
• Sample CAD Drawing: Ensure you have a sample CAD drawing file (e.g., “sample.dwg”) in your document directory.

Import Namespaces

Begin by importing the necessary namespaces into your .NET application. This step is crucial to access the functionalities provided by Aspose.CAD for .NET.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.CAD;

Step 1: Load CAD Drawing

Start by loading the CAD drawing into an instance of the Aspose.CAD.Image class. Ensure you have the correct file path for your sample drawing.

string MyDir = "Your Document Directory";
string sourceFilePath = MyDir + "sample.dwg";

// Load a CAD drawing in an instance of Image
using (var image = Aspose.CAD.Image.Load(sourceFilePath))
{
    // Your code here...
}

Step 2: Create BmpOptions

Create an instance of the BmpOptions class, which is responsible for specifying options when saving the CAD drawing as a BMP file.

Aspose.CAD.ImageOptions.BmpOptions bmpOptions = new Aspose.CAD.ImageOptions.BmpOptions();

Step 3: Set CadRasterizationOptions

Instantiate the CadRasterizationOptions class and configure its properties for vector rasterization.

Aspose.CAD.ImageOptions.CadRasterizationOptions cadRasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions();
bmpOptions.VectorRasterizationOptions = cadRasterizationOptions;

Step 4: Set UnitType Property

Set the UnitType property of CadRasterizationOptions to specify the unit type for resizing. In this example, it is set to Centimeter.

cadRasterizationOptions.UnitType = Aspose.CAD.ImageOptions.UnitType.Centimeter;

Step 5: Set Layouts Property

Specify the layouts you want to include in the resized drawing by setting the Layouts property.

cadRasterizationOptions.Layouts = new string[] { "Model" };

Step 6: Export to BMP

Finally, save the resized layout as a BMP file using the Save method.

string outPath = sourceFilePath + ".bmp";
image.Save(outPath, bmpOptions);

Now you have successfully adjusted the size of your CAD drawing using Aspose.CAD for .NET!

Conclusion

In this tutorial, we walked through the process of resizing CAD drawings in .NET using Aspose.CAD. By following these steps, you can seamlessly integrate this functionality into your applications, providing a smooth user experience.
