When I try to extract table from pdf that is from AutoCad, it doesn’t work.
It returns error with message “internal error occured during work of tableabsorber”
but other pdf that is not from Autocad. it works well.

here is my code. What can I do for this issue?

        Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(file);
        Aspose.Pdf.Page p = pdfDocument.Pages[1];
        Aspose.Pdf.Text.TableAbsorber absorber = new Aspose.Pdf.Text.TableAbsorber();
        absorber.Visit(p); //here error occured
