Thank you so much for the help. It works very well after defining the surface.<br><br>A minor thing is the generated mesh is a little bit nonuniform, i.e. of different size. This can be seen from the attachment. But this is really a minor thing. I think it is because the nodes on the curve is not uniformly distributed when Inkscape outputs DXF file. <br>

<br> </div>Don't know if it is the shortest route, but it works ...<br> <br> - In inkscape "save as" .dxf<br> - open in qcad and save as dxf 2000<br> - use perl script in utils/converters/autocad/dxf2geo.pl to convert to geo<br>
- in gmsh define surface and mesh<br> <div><br> > I am wondering if anyone has done this before. It will be great if I can<br> > reload the output into inkscape afterwards.<br> <br> </div>Just save as svg, probably without background.<br>
