  Hi Kaspar,
  Sketchup is a 'poly' modeller where the surfaces are made up of triangular facets, IGES is a universal translation of NURBS surfaces so it's not possible to directly convert poly data into IGES you need something in between, a program like 'Mesh to Solid' http://www.sycode.com/products/mesh_to_solid/index.htm to convert poly data to NURBS or T-Splines.

  Well i just came on two solutions via autodesk. In sketchup , save the skp file as a dae file. ( or as a kmz, rename as zip, extract en search for the dae file )

  With the free software Meshlab import the dae and save it as a dxf;. Open this dxf In Autocad Mechanical and save it as Iges.

  Or open the dae file with the autodesk free software Fbx convertor. Convert this file first as fbx. Convert the fbx-file as dxf and open it in Autocad Mechanical to save it as iges.

  export skp to stl
  load in sw (surfaciq stl)
  save in iges

  (off course the stl need to be perfectly closed)

  Here's a new plugin for Sketchup for exporting directly to IGES that may be useful: http://forums.sketchucation.com/viewtopic.php?f=323&t=43307

  I haven't tried it myself(haven't any need for it), so I can't verify if it works or not.
