Some contents are missing after converting dwg/dxf to PDF using Aspose.CAD(C#)


I found issues on testing Aspose CAD for .NET

Some contents are dropped after I convert some dwg/dxf files to PDF.

I used your ExportToPDF sample itself, which I changed source file path only.

I am sending source dwg/dxf files, correct PDF files, and output PDF files created with Aspose CAD for .NET.
You can download them at https://www.dropbox.com/s/6toqf5zb9pknjoi/MissingContents.zip?dl=0

I created reference PDF files for comparision with AnyDwgToPDF - http://anydwg.com/dwg2pdf/

The missed contents are various for source dwg/dxf files.

For examples;

  1. 1344465490.dwg – all factional numbers were dropped. You can find the positions at 1344465490_IssuePosition.png. I suspect that it may result from unavailable SHX fonts. I think that it is very critical to miss any number in drawings.

  2. Bottom_plate.dwg, Gear_Pump_Subassy.dwg, LEVER_DETAIL.dwg, Pump_wheel.dwg, Trolley_Structure.dwg, Wheel_casing.dwg, robot_handling_cell.dwg
    Some lines were dropped.
    I downloaded them at Autodesk website (it means that they must be very popular and must be converted well.) –

  3. SMA-Controller.dxf – all contents are dropped.

You can find the output of Aspose and anydwg are different at a glance for all files.

If the issues will be solved, I will buy Aspose CAD for .NET in a week.

Best regards.
