Try exporting the curves only.

If you need filled objects with color use a hatch instead. The benefit of this is the object then displays correctly in Illustrator or here in Coreldraw as shown

Hi Ly -

Those are the isocurves of the object that are visible in, e.g., the Wireframe display mode.
To export this to PDF as you see it in the viewport, you will have to use the Raster Output option in the export dialog. If you need vector output, you will have to use the workflow that Michael described.
