      uh..okay
      suddenly I feel like "penny" talking to "Sheldon" πŸ˜„

      ...actually I wondered if there was a way to automate the trace with some raster/vector software.

        The vectorizing programs I've tried all made very ragged vectors which translated into huge segment counts in SketchUp. If the image is suitable or made suitable for it, TIG's plugin would be great. For most of the tracing I need to do, it would take as long to make the image suitable as to just trace it and get it over with.

          That is what TIG is offering in his plugin. However the first step is make the background transparent in an image editor if it is not already so, so that the software "knows" where to make the trace.

          There are automatic vector-izing programs but probably not what you want for a cut-out. Varying success from what I see.

          Looking at "Intarsia" it looks like these are linework patterns, not cut-out texture images, so I sense TIG's tool is not what you want. Probably drawing by mouse (or tablet) is going to be faster and cleaner.

              Pilou, would you show us the vector lines you get from that image? Put them into SketchUp.

                  I make a snaphot from the su forum!
                  With default parameters and without regulate anywhere in any progs that give that! (skp final file linked)
                  Inside Expression 3 (i have not the original expression file by graphinc! so snapshot above so JPG compression don't help! --> mutiply colors! )
                  You can of course modulate the start colors for have a more precise result!
                  (here only 4 colors! Suffisant if you want just the outlines! you can take till 40 color)

                  redfish1.jpg

                  You will have choice to export in different format Illustrator Ai ...
                  exportai.jpg

                  ...and EPS, PDF and FLASH

                  I had taken AI 7.0 then import inside Moi then export directly in format SKP πŸ˜‰
                  Inside Moi (who can accept also EPS, PDF )
                  redfishmoi.jpg

                  Moi export default parameters
                  redfishmoi1.jpg

                  Inside SKP : for a direct work without any regulates it's not so bad! πŸ˜‰
                  Funny the original black circle eyes has disapeared maybe black is the transparent color somewhere!
                  Expression 3 is a crazzy free prog! 😎

                    That is interesting on many levels and I bet it would be suitable for many artistic inflections.
                    Just to satisfy your curiosity etc

                            In the Extension Store: https://sketchucation.com/pluginstore?pln=BezierSpline

                            Best would be to install the Sketchucation Extension Store tool under Resources at the top of this page. Then use it to install extensions hosted here.

                            There's also FredoSpline which has more options than the older Bezier Spline.
