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.
