      Sounds promissing....Thanks for the script...It looks like there is a less and less reason to leave SU...

        so far, it seems the best option is to create two halfs of the closed loop you want (be it a circle, elipse or anything else). Than you loft and join them.

        If you want to loft a circle to a line, MAYBE its possible to cut the circle in two. Then you loft half the circle to the line, and then you loft the other half of the circle to the same line. Then you join the two sides.

          Well i was thinking about leaving SU and one of those reasons where no loft support.
          Until now.
          You are really making Great Plugins you are very generous an talented man.
          Thxs a lot Chris.

              OK good news is it works on my laptop on both SU7 and SU6.
              On my other XP I found culprit. It is tt_double_cut.rb.... As soon as I removed it(as this was only one which was not on all comps) loft started to work.
              I know Tom's script is only alpha but it seems to clash with yours.

              Double-cut should not be used in a production environment. It makes SU unstable, liable to bug-splats and interferes with the observer events. It will need major rebuilding to make it work, so I won't be looking to track down bugs in in the alpha. It is in it's current state FUBAR. I need to get my thinking-cap on first before I start on re-writing it. (I also need a minor break from it as well as my frustration level increases just by looking at it as it is now 😞 )
              Sorry for the inconvenience.

                Sorry to hear it Thom, its a plugin with a lot of potential. Hopefully the observers situation will get worked out and stabilized in future releases.

                Good luck with it when you feel like getting back to it!

                  Hi Chris, and all the others (my first post)
                  I find the first version of your script (0.1a) is realy a good start. The loft tool in moi 3d have the same result with two curves. The bezier connection seems only necessary with tree or more curves. It makes a smooth connection between curves. Anyway. This is the tool missing in sketchup. How brave you are! Thank you for your script, and all of you who keep sketchup fascinating.
                  Moujiik.

                    Hey moujiik, that is a great image that clearly shows what I was asking about. Indeed it just makes straight connections from point to point with only 2 splines. Its not until you add a 3rd spline that it starts to use a bezier connection.

                    In the current version, I faked in a bezier curve even on 2 curves, and I think I'll leave it in place. Partially because I've also now added the ability to control the amount of curve. So if a user selects just 2 splines and wabts the straight straight connections, with multiple segments, it will be possible in the next version I release.

                    Thanks for the image and the kind words!

                        I think this may already be enough to allow me to create my uplifted neo-dolphin suit!

                          Dear Chris,

                          What I actually did to get the bowl was to:

                          • start with a circle about the origin, and on the X-Y plane
                          • explode the circle
                          • delete one segment
                          • move and copy the modified circle in the Z direction
                          • scale the upper circle about its centre
                          • use simple_loft
                          • stitch the open part using the line tool

                          Regards,
                          Bob

                            What happens if one tries to use two half circles to create a bowl (see image). The edges are not suitable for joining.

                              Ahh, very true. Well, someday I'll get it so that it works with circles and ellipses and all closed splines. Then it will work much smoother 😄

                                This is for me the problem with loft.
                                There are other tools that creates surfaces bounded by 2, 3 or 4 curves..
                                It looks like a double loft.
                                But something like this is possible?

                                  Yeah, something like that is probably possible. Its not something I'm working on. But maybe in time. I would need to play with it in rhino or 3dsmax and figure out what its really doing to the geometry. I can't tell exactly how its making the cross splines. But I'm sure I could figure out if I played with it long enough.

                                    Yes, but beziers overlap. Better way is to have say circle and circle losing one segment at same position and lofting remain.

                                          Chris i think found a little bug.
                                          When I try to loft two lines inside a group SU crashes.
                                          Everything else is working perfect
