  • 3. Presenter Background Dr Julien de Charentenay: Practical engineer with excellent CFD knowledge and an interest in software development
  • 4. SketchUp • History 2000 Released by @Last Software 2006 Acquired by Google 2013 Acquired by Trimble • Programs of interest K-12 African University Visiting Professionals Project Spectrum
  • 5. SketchUp
  • 6. SketchUp Basics • SketchUp Make (Free) vs SketchUp Pro • Modelling principles • Plugins
  • 7. SketchUp Limitations • Minimum length "tolerance factor for length is 0.001 of an inch" Source: http://sketchucation.com/forums/viewtopic.php? f=15&t=25175&p=218997#p218989 0.001 inches = 0.0254 millimetres

  • 27. SketchUp, what's not so great? • Watertightness • Plugin to assess watertightness http://sketchucation.com/forums/viewtopic.php? t=30504 • More attention with the advend of 3D printing
  • 28. SketchUp, what's not so great? • IGES/STEP support • No in-built support • Available through - paid - extension(s)
  • 29. SketchUp, what's not so great? • Importers and plugins speed of execution • Due to speed execution, some functionalities may be impractical for large cases.
  • 30. Overall SketchUp is a great 3D design tool: Easy to pick-up and ease; With a good base of users; Very practical for quick modelling for use in conjunction with openfoam; But has practical limitations.
