Sketchup to dxf file conversion - one job & potentially ongoing work.

Hello, we have a lot of sketchup files that I'd like converted to dxf. I can do this myself with the dxf exporter, however it exports arcs and circles as a number of flat sides, so they need replacing with the proper arcs and circles. Anybody with both reasonable Sketchup and FreeCAD experience should be fine. I'm guessing it would be done on a job-by-job basis, or perhaps per hour, with in pre-agreed boundaries.

The Sketchup files have all been done in version 8, and I can share the Sketchup installer, DXF exporter and 'point at center' plugins if required. Attached are two files to give you an idea.
