        Dear Richard,

        How did you produce the shape in your third image. Could you put together a small tutorial?

        Thanks,
        Bob

          I'm not Richard, and he may have a better way, but here's a tutorial on how I did it.

          It seems amazingly complex when I write it all out, but it was simple and quick enough when I was doing it.

            Hi SchreiberBike,in your tutorial you mention:

            Explode all the components.
            Use the Skin.rb ruby to connect the faces and to
            clean up the excess lines.

            Could you explaine what you mean and how you do that with Skin.rb ruby.
            Thanks.

              Hi Pagan,

              Here you can find different versions of the skin.rb.
              It will alsoput a toolbar onto your work area (you may need to activate it from the View > Toolbars menu). Select either the faces (if you have them) or the lines/edges and run the script. Play with it a little bit until you have a grip on it (sometimes it seems to bee a bit tricky).

              Gai...

                  Dear SchreiberBike,

                  Thanks for for putting together the tutorial. I will have to give it some thought.

                  Kind regards,
                  Bob

                    A quick tutorial on how I created the image in my last post and the first image I posted. This was really just an experiment to see how/if a shape could be chamfered and does not work for every shape.

                    A - Create your basic shape and group it:

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel1.jpg

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel2.jpg

                    you can see in this example there are not all lines carry on across the whole object, thus there are no 'ribs' as in SchrieberBike's example
                    B - Create your radius

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel3.jpg

                    C - Create a flat plane below your object and using the sandbox tools drape your object onto the flat plane
                    Edit: There shouldn't be any need for this step instead keep a copy of the shape of the object when you create it, but this way would be good for more complicated shapes created from lots of intersections etc.

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel4.jpg

                    D - Delete excess geometry, move your created radius down to here and offset the shape inward to the points of the radius

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel5.jpg

                    E - Copy the top of the shape up to the points of the radius (similar to idea as above)

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel6.jpg

                    F - Push pull every other section of the offset shape (step D)

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel7.jpg

                    G - Intersect the shapes created in step E, and then delete the geometry from step F

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel8.jpg

                    H - Delete excess geometry so you are left with the top cap and contours for the chamfer

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel9.jpg

                    I - Use skin.rb to skin the chamfer

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel10.jpg

                    J - Explode all the geometry, soften/smooth edges (its also worth deleting any coplanar geometry to tidy things up a little)

                    http://www.rsw3d.co.uk/sketchup/bevel/bevel11.jpg

                    Heres the model as well bevel.skp

                      Wow Richard, that is ingenious. Thanks a bunch for your clear and concise explanation!

                        Just been experimenting with this, and it works well for more complicated shapes also:

                        http://www.rsw3d.co.uk/sketchup/bevel/bevel_complex1.jpg

                        bevel_complex.skp
                        This was done the same way as above, except it was rotated so the front face with the bevelled/chamfered edges faced upwards.
