Cannot convert sample.dwg to pdf

I’m trying to convert the sample.dwg (as downloaded from github) to a pdf file using the
CadlayoutstoPDF,cs but to no avail

There is no output pdf file at all ? The following is the code that I used

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.CAD;
using Aspose.CAD.ImageOptions;
using Aspose.CAD.FileFormats.Cad;
namespace Aspose.CAD.Examples.CSharp.Export
{
public class CADLayoutsToPDF
{
public static void Run()
{
//ExStart:CADLayoutsToPDF
// The path to the documents directory.
string MyDir = RunExamples.GetDataDir_ConvertingCAD();
MyDir = @“C:\Users\N\Downloads\Aspose.CAD-for-.NET-master\Examples\Data\DWG-Drawings”;
string sourceFilePath = MyDir + “sample.dwg”; // + “conic_pyramid.dxf”;
// Create an instance of CadImage class and load the file.
using (Aspose.CAD.Image cadImage = (Aspose.CAD.Image)Image.Load(sourceFilePath))
{
// Create an instance of CadRasterizationOptions class
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 1600;
rasterizationOptions.PageHeight = 1600;

            // Set the Entities type property to Entities3D.
            rasterizationOptions.TypeOfEntities = TypeOfEntities.Entities3D;

            rasterizationOptions.AutomaticLayoutsScaling = true;
            rasterizationOptions.NoScaling = false;
            rasterizationOptions.ContentAsBitmap = true;

            // Set Layouts
            rasterizationOptions.Layouts = new string[] { "Model" };

            // Create an instance of PDF options class
            PdfOptions pdfOptions = new PdfOptions();
            pdfOptions.VectorRasterizationOptions = rasterizationOptions;

            MyDir = MyDir + "CADLayoutsToPDF_out.pdf";

            // Set Graphics options
            rasterizationOptions.GraphicsOptions.SmoothingMode = SmoothingMode.HighQuality;
            rasterizationOptions.GraphicsOptions.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;
            rasterizationOptions.GraphicsOptions.InterpolationMode = InterpolationMode.HighQualityBicubic;

            // Export to PDF by calling the Save method
            cadImage.Save(MyDir, pdfOptions);
        }
        //ExEnd:CADLayoutsToPDF            
        Console.WriteLine("\n3D images exported successfully to PDF.\nFile saved at " + MyDir);
    }
}

}

@annewilson,

Sorry for the delayed response. We are working on this issue and get back to you very soon.

@annewilson,

Can you please try using latest Aspose.CAD 17.12 on your end and if there is still an issue then please provide the source DWG file that you have used along with generated output PDF and desired PDF. We will investigate the issue further on our end to help you.
