[Inkscape-user] Edges of polygon surface

Hi,

I'm exporting 3d surfaces from Mathematica. This creates a large number of polygons where neighboring polygons have two equal vertex-points.

Following problem: Although no stroke is used for the polygons and the coordinates of neighboring polygons are exactly equal, theres a teeny tiny space visible between them.

One hack around is to scale every polygon to 100.01% so that it overlaps a bit, but this is no solution.

Does anyone have hint for me?

I can of course provide a sample svg if someone wants to have a look.

Cheers Patrick
