How to get 2D export to Inkscape at high quality?

The AI file format does not work. I exported from Rhino having selected “Save Geometry Only”, assuming that this creates a very simple AI file.

When I import into Inkscape 0.48 / Windows 7, that fails with error messages:

  • Adobe Illustrator 9.0 and above (PDF based):

    Failed to load the requested file C:\Temp\logo.ai

  • Adobe Illustrator 8.0 and below (Postscript based):

    1. UniConvertor failed

    2. Failed to load the requested file C:\Temp\logo.ai

It seems that:

  • Rhino exports to Illustrator 8.0 and below format.

  • The tool UniConvertor conversion tool used by Inkscape has issues on Windows 7. See comments on Inkscape bug 745997. Inkscape 0.48 includes UniConvertor 1.1.5.

    A recommended workaround is to install UniConvertor 1.1.4 separately, and then do the conversion manually from the Windows command prompt:

    uniconv input.ai output.svg

    I have not yet tried that.
