Adjusting CAD Drawing Size Using Unit Type with Aspose.CAD for Java

Introduction

In the ever-evolving realm of Computer-Aided Design (CAD), precision and adaptability are paramount. One common requirement is adjusting the size of CAD drawings based on specific unit types. Aspose.CAD for Java emerges as a powerful ally, providing seamless capabilities for manipulating CAD files programmatically.

Prerequisites

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

Java Development Environment: Ensure that you have a functional Java development environment set up on your machine.
Aspose.CAD for Java Library: Download and integrate the Aspose.CAD library into your Java project. You can obtain the library here .

Import Namespaces

In your Java code, include the necessary namespaces to access Aspose.CAD functionalities. Add the following imports:

import com.aspose.cad.Image;
import com.aspose.cad.ImageOptionsBase;

import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PngOptions;

Now, let’s break down the process of adjusting CAD drawing size using unit type into manageable steps:

Step 1: Define Data Directory

String dataDir = "Your Document Directory" + "CADConversion/";

Set the path for the directory where your CAD files are located.

Step 2: Load CAD Drawing

String sourceFilePath = dataDir + "sample.dwg";
Image image = Image.load(sourceFilePath);

Load the CAD drawing using Aspose.CAD’s Image class.

Step 3: Create BMP Options

BmpOptions bmpOptions = new BmpOptions();

Instantiate the BmpOptions class for exporting the CAD layout to BMP format.

Step 4: Configure Rasterization Options

CadRasterizationOptions cadRasterizationOptions = new CadRasterizationOptions();
bmpOptions.setVectorRasterizationOptions(cadRasterizationOptions);

Create an instance of CadRasterizationOptions and associate it with the BmpOptions for vector rasterization.

Step 5: Set Unit Type

cadRasterizationOptions.setUnitType(UnitType.Centimeter);

Specify the desired unit type for the CAD drawing. In this example, we’ve set it to Centimeter.

Step 6: Set Layouts

cadRasterizationOptions.setLayouts(new String[] { "Model" });

Define the layouts to be considered during the export. In this case, we’ve selected the “Model” layout.

Step 7: Export to BMP

String outPath = sourceFilePath + ".bmp";
image.save(outPath, bmpOptions);

Finally, save the modified CAD drawing in BMP format.

Conclusion

With Aspose.CAD for Java, adjusting CAD drawing sizes becomes a breeze. This tutorial has walked you through the process, emphasizing each step’s significance in achieving precise results.
