      Now you've 2 groups. The cylinder and the points.

      Edit the points group the manipulate the cylinder group. The points can be moved individually or in multiples. Pick a row and move them. The mesh should update when the move is committed.

      Just practice 👍

        Thanks for the help. I'm starting to make it look like the image.
        It's going to take practice you're right. This is cool!

            it is at the bottom of the first post, just click on it and save it to your plugins folder.

                    Hi, itscabbage:
                    I would highly recommend reading through the entire series of pages in this thread. Among the pages are animations, visuals etc. that can provide information on how to use the tool. If you are unable to activate it, perhaps you should check to see if it is in the proper folder. This is dependent on whether you are using Windows or Mac.
                    FFD does take a little practice.
                    And, if you haven't already done so, update your profile. This will enable helpers to determine specific solutions, especially with regard to operating systems.

                    I take the slow, deliberate approach in my aimless wandering.

                      For some reason, only the first version works for me.

                      I set NxN
                      width=11
                      depth=11
                      height=1
                      subdivise=false

                      First version everything is OK, scale move rotate...

                      Second version, nothing moves (see ruby report)

                      Tig's version, trying to move the original group just disappear? 😲 no console report.

                      Any idea?

                        I made the adjusted version because the older versions were all causing issues, clashes with other scripts etc, the observer was very flaky...
                        My version works fine for me when tested using your settings, although I don't fully understand the 'moving the group...disappear' issue 😕 what disappears ? If you move the group away from the guides it will deform differently...
                        You can only have one set of FFD guide-points at a time, so is this your issue ?
                        The 'second' version had the most fails so I'd expect the litany of error messages...

                          I set NxN parameters and clicking ok the group disappears, it is still in the outliner but nowhere in the model.

                            I also try with only SketchyFFD.rb in plugins folder, same result.

                              It works fine for me with z=1 set, provided that the geometry has some 3d-ness.
                              If I draw a grid 10x10 as a flat 2d group it does then fail !?
                              Not having written the original code [I just fixed some known issues] I am unclear why...

                              Adding a short vertical line to the grouped mesh fixes it... Capture.PNG I'll check though the code and see if I can trap for this...

                                If I add a vertical line in the group it works.
                                Good to know.

                                            There is little difference with this update !
                                            How are you trying to deform a sphere ??
