Hello. We need more details to reproduce this. I used this code:

using (Aspose.CAD.Image cadImage = Aspose.CAD.Image.Load(fileName))
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 4000;
rasterizationOptions.PageHeight = 4000;
rasterizationOptions.Layouts = new string[] { “Model” };
PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
pdfOptions.VectorRasterizationOptions = rasterizationOptions;
cadImage.Save(outPath, pdfOptions);

Here is the result: Sample.dwg.pdf (503.9 KB)


loading of SHX fonts with

rasterizationOptions.ShxFonts = new string[] {

additionally allows to scale these symbols and make them thin.

as I can see, there are some issues with SHX for Java, I created CADJAVA-10799 to cover this.
