      I can't get this plugin to work and I need to use it desperately for some artificial snow I'm making for a building roof top.

      I put it into plugins folder and then I tried tools but no luck.

      An Install guide would be helpful.
      Thank you

      Install by putting the script in your plugins directory.

      As it says on the first post

      Edit, I see it's on right click menu FFD now but I only have 3 commands?
      Lock, unlock and make patch. None of them seem to do anything?

      Could someone direct me to a guide to using this plugin. Thank you.

        FFD won't allow you to create a N x N cage if it's raw geometry or a component

          So how do you create the cage? I am just starting at Sketchup.
          I've been using it for 1-2 months now.

          Here is what I'm trying to make.
          The snow cap on top of this window.

          I already made a cylinder. Radial bended it around the top. Now i need to deform it like snow

          How do you suggest I do this. Thank you.

            Have you read the description in the first post?

            Make your cylinder a group. Right click and choose N x N. Input values for height, depth and width. These will be the points that weight your cylinder.

            Edit the point group and adjust points accordingly.

            It's best if you attempt to do this then ask when things become difficult.

              Ok I've completed your steps up to "edit point group"

              I'm not quite sure how, could you explain it? Thanks for the patience.

                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.

                                        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.

                                            Here's my update http://sketchucation.com/forums/viewtopic.php?p=36127#p36127
                                            The recently reported NxN issues with NaN [0.0/0.0] & Infinity [1.0/0.0] fixed, these occurred when the selected group was 2d & NxN height=1...
                                            Also the NxN dialog now remembers the last used values that session for the NxN lattice [width, depth, height, subdivide]...
