          That's a great example of blending shapes with creases. I'm thinking I should set up a dedicated section on the website for these types of studies.

            But what about the thicker lines in that render - representing the original edges? How is that done? Multiple passes?

              Since two of your plugins are not enough πŸ˜‰ :

              • SubD
              • Edit group
              • Select all
              • SeletionToys: Select only -> Edges
              • Group selected edges
              • Gropued edges without faces are treated as profiles
              • Increase profile width in the style settings
              • Exit SubD group
              • Unsmooth quads

                    Can you explain to me, why the first attempt fails. Why I should select one edge of triangulated face, that the second attemt must be fine.

                      The Convert triangulated Mesh to Quads function doesn't always succeed. It's hard, impossible, to reliable determine exactly how the mesh should be converted as it would require AI understanding of the mesh's topology. In your example it's easy for use humans to see what should be a quad, but not for a script. The script doesn't even take into account soft/smooth/hidden properties - it just sees a set of triangles.

                      In the case of your mesh there it looks like you have hard edges and then some soft+smooth edges between triangles pairs. Then you want to use the Convert SandboxTools Quads to QuadFace Tools quads instead. (left to the monkey icon). If those edges where hidden you you'd want to use the Blender Quads to QFT Quads function (the monkey icon).

                        Humm, i was in similar situations... means that either more documentation is needed to make it easier to understand when to use each function, or maybe if you would think appropriate, to make the quad-detection script to be more "intelligent", so it can take into consideration multiple parameters at the same time. For example not all Fredo Tools are good in creating or preserving quads... but they do smoothing. So, would be good to rely better on conversion.
                        Thank you! Keep up the good work ! πŸŽ‰

                          Yes, better documentation is indeed in need - as well as improving the tools. But docs are on the top of my list when I get home from my travels next week.

                          I plan to set up a new site for QFT - move away from the BitBucket wiki.
                          Better text and visuals describing the various features of QFT. GIFs to illustrate common topology pattern.

                          And extend SUbD's site to include more examples of how various topology patterns subdivide.

                            I was thrilled by the panton chair example shared by Ithil3d on youtube. I thought I'll build one trying slightly different method. A good few minutes and here's what i got.

                            model

                            test render

                              This is a very good SubD example!

                                Yes the difficulty with Subdivision modeling against the Nurbs modeling where you have yet all the curves of the model, is to imagine the "rustic" cubic form before it's transformation! πŸ˜„

                                  Is there any plugin working like Blender's Add Loop cut, see link below? I think that this would be really useful when using SubD.

                                    If you look back a little you will see that we talk about that too, it's called Quad face tools, you can find it in the plugins library.
