        One possibility
        Draw a rectangle
        Pull it with Ctrl any time you want
        Select all (triple click)
        Move it one time + CTRL = Copy
        Type "10*" (or more) = Multiple
        Select all (triple click)
        Group it
        Select group Right Click / FFD
        Edit the goup "FFD"
        Move points
        Et voilร  ๐Ÿ˜‰

            There's a subdivide feature in the script.right click> FFD> NxN> set subdivide to true.

              Yes but will be any effect on the subdivide of a simple rectangle!!!
              Nothing will arrive when you will move a point of the FFD!

              Seems the only easy methode is draw a rectangle with the Sandbox ๐Ÿ˜„

                Hi..

                I think there might be a problem with FFD an ASGVIS V-ray for scetchup.. FFD did not work while i had V-ray installed but now that i have uninstalled V-ray FFD works fine again.. Same problem as with subdivide and smooth script..
                can anyone else confirm this ?? Btw, FFD is a brilliant script. ๐Ÿ‘

                    Works nice! But "transformations reset" needs sometimes before FFD starts.

                        this looks like a wonderful ruby!!!

                        too bad it's not working for me, it doesn't do anything, and when I try undoing it beaks my geometry apart!

                        would have loved to use it ๐Ÿ˜ž

                          Its not over yet. If its not working, then its installed wrong or your using it wrong. Or you have version 4 of SU ๐Ÿ˜„

                          Could you provide a better description of what its doing wrong? Perhaps screenshots, maybe a video. Just give us some more detail and we'll get it working for you.

                            I'm running Sketchup 7 and just added your FFD tool. I can move points but there is no 'update FFD' option when I'm finished. Is FFD not compatible with Sketchup 7?

                            Thanks!

                              The shape should update automatically, you might have to give it a bit of time, though.

                              If that doesnt work delete the control points, explode the group, regroup and try again.

                                After waiting on a 2.4 GHz dual core XP system, nothing changed. I've just installed FFD on my computer (2.1 GHz dual core) and created a circle so I could elongate one point. Nothing. This is disappointing.

                                  Have you tried it on 3d geometry? i think it can work on 2d things, but ive never gotten the hang of it.

                                    I create a sphere, group it, right-click and do 3x3 FFD, enter the new group with Construction Points, move some to another position, exit the group, right-click the sphere group and choose Update FFD. Nothing happens.

                                    Can you open the ruby console and see if it is printing any errors?

                                      Hi Chriss,

                                      it really makes fun to work with FFD! I looked at your code and found the factorial function where you mentioned to encrease performance by adding a table for factorials. I made it dynamic and it boosts your code! Just replace the section with:

                                      
                                      #used by calcBernstein. could be replaced by a table since in 
                                      #this application n is never more than 3 (number of control points).
                                      $fTable = []
                                      def factorial(n)
                                          sum = $fTable.rassoc(n)
                                          if sum
                                          	return sum[0]
                                          else
                                      	sum = 1
                                      	sum.upto(n) { |i| sum *= i }
                                      	$fTable << [sum, n]
                                      	return sum
                                          end
                                      end
                                      

                                      Ciao, Stefan

                                        Thanks Stefan! Its a nice idea. I updated the plugin with an adaption of the code and applied it to the Bernstein Polynomial as well. It sped up the initial weighting of a big model from 75 seconds to 15 seconds.

                                        I also figured out a way (in theory) to speed up the actual deformation by like 50x. The only problem is I would have to handle moving the control points without using any of Sketchups tools like select, move and rotate. Ugh!

                                            Thank you for the update. It really is an effective modeling tool.

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