Missing coloumns while converting DWG to PDF using Aspose.PDF for Java

I use Aspose.cad For Java 18.3 on trial, when I convert dwg to pdf, only one column of CadInsertObject objects appears and the object has several columns. Could you tell me why?


I have observed your comments and request you to please try using latest Aspose.CAD 18.8 on your end. If there is still an issue then please share the source file, generated output, desired output and used sample code. We will be able to investigate the issue further on our end on provision of requested information.

Thanks for answering!
I had already searched, but I did not find the aspose.cad 18.8 jar file, only 18.3 in the link below.

This is the code I am using for converting dwg to pdf:

import com.aspose.cad.Image;
import com.aspose.cad.SizeF;
import com.aspose.cad.fileformats.cad.CadDrawTypeMode;
import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PdfOptions;
import java.io.File;
import javax.swing.JFileChooser;

public class DwgToPdf {

public static void main(String[] args){ 
    new DwgToPdf().start();

private void start(){
    String srcFile = askForFile().getPath();
    String srcFileOut = new File(srcFile).getParent()+"/DwgToPdf.pdf";
    Image image = Image.load(srcFile);

    CadRasterizationOptions cadRasterizationOptions = new CadRasterizationOptions();

    cadRasterizationOptions.setPageSize(new SizeF(5000,2000));

    PdfOptions pdfOptions = new PdfOptions();
    image.save(srcFileOut, pdfOptions);

private File askForFile(){
    JFileChooser jfc = new JFileChooser();
    int action = jfc.showOpenDialog(null);
    if(action != JFileChooser.APPROVE_OPTION){
            return null;
    File file = jfc.getSelectedFile();	
    return file;


This is the dwg file:

This is the pdf generated without problems, the objects that are getting lost when converting are marked blue. This objects are blocks, and have several columns, however only one column is drawn when converting to pdf through aspose.cad:
