Hi,
When I convert [this file] using the code below, the output file is missing a sidebar on the right side of the CAD file, is there an option I am setting wrong?

{
var inputFilePath = “input.dwfx”;
var outputFilePath = “input.pdf”;
Console.WriteLine($"Loading file: {inputFilePath}");
try
{
/*using (var cadImage = Image.Load(inputFilePath))
{
var rasterizationOptions = new CadRasterizationOptions()
{

};
var pdfOptions = new PdfOptions
{
VectorRasterizationOptions = rasterizationOptions
cadRasterizationOptions.UnitType = Aspose.CAD.ImageOptions.UnitType.Centimenter;
};
Console.WriteLine($"Converting {inputFilePath} to {outputFilePath}");
cadImage.Save(outputFilePath, pdfOptions);
}*/
//using (Aspose.CAD image = Aspose.CAD.Image.Load(inputFilePath))
