      Hi Everyone!

      I'm new to this forum. I have been using sketchup for some time but now i want to use it for more complex modelling. I come across this problem with the round edge plugin of Fredo6 and i don't know how to work around it. I hope you guys can help me out!

      I want to make a rounded edge on a complex curve on a box. Both the side and top faces of the box is curved leaving for a complex curve. See the attachment for screenshots:

      Here is the sketchup file:
      2017_03_20_complexe curve radius2.skp

      Unfortunately, making the rounding results in bad geometry. The radius size should be doable, as it is not bigger then the side radius. I hope one of you experts are able to help me out with this problem!

      cheers!

        Sorry no time for see that!
        But when you post a file SKP post save as V6 for a more large audience! ๐Ÿ˜‰

          A few pointers...
          It is fixable see the attached v6 SKP.
          But it needs some reworking to ensure the smoothed edges on the curved top align with the ends of the smoothed edges in the rounded corners.
          Remove unnecessary divisions.
          Also some tiny bits of edges can be merged to avoid issues.
          Also change you Model Info > Units to NOT snap to 1mm, it'll make the fix much easier...
          I've attached the SKP but please try the fixes yourself, so you learn...

            Hi TIG,

            Thank you so much for helping me out so quickly! I do have some questions though:

            • How did you remove the unnecessary divisions? If i do it the top faces delete as well.
            • "Also some tiny bits of edges can be merged to avoid issues." How do you merge these edges?

            Thanks again for the help. I really appreciate it. I hope to hear from you soon.

            cheers Jelle

              In the 'yellow-blob' example I deleted the three edges and redrew one side edge and a new crossing smoothed edge.
              You could also try moving a vertex with no preselection and the Move tool.
              To make a neat sloping last face I made large rectangle and grouped it temporarily, then overlaid it on the problem edge face.
              I then use Move on the relevant top vertices to lift them up in the Z [blue] so that they are projecting above the temp-group.
              Now I exploded the temp-group.
              Then selected all of the geometry and intersected it.
              I then deleted the various unwanted geometry to leave a good raking face.
              This makes a good form that will accept a rounded set of edges...

                Curious seems Round Corner don't works inside the SU 2016! ๐Ÿ˜ฎ

                Else for your object I have no problem for round uper face in 2015! ๐Ÿ˜ฒ
                I select only the edges angle and automatically all perimeter is selected!
                Even you have some edges overlaping!

                  Thank you again TIG!

                  I was able to follow your instructions and make it work. There is still one thing that is bugging me. When i try it, i see the top face triangulated (or something), while with your model it looks perfectly smooth. Why is this? Any ideas?

                    If you follow my advice and still get some extra lines, then you can use a 'delete-coplanar-edges' tool, or try erasing those you suspect of being unneeded - if they are redundant then their removal will not adversely affect the two faces which should now merge into one.
                    If deleting the edges loses the faces then something is adrift as they were therefore not 'coplanar'...

                      Thank you very much! i will try to download a plugin for that. I still don't know how the result can be different from your model though.. oh well!
