      The first tool exists right now with courtesy of Chris Fullmer :[Plugin] Component Stringer

      I think Remus is talking about a tool to simulate rope or chains - which is not what Chris' tool is doing.

        A remark to Remus: Your Catenary Curve is made with only 16 segments. It's probably too few in many cases. It would be better to add the choice of this number( 😉 )

        I'll have a look at it 👍

          Hi thomthom,
          You are rigth! I had probably been taken by the hurry of enjoyment. Chris's "Component Stringer" is a very cool tool, but intending to do a different job.

          We can make a chain with it but it very uneasy and far from perfection!

          @tig said:

          Make half chain link (U) and use this tool then edit that chain and copy/hand the U geometry into an O loop of say 2.2 the original length, now you have your links; us 'make unique' on one of the links, edit it and rotate its contents 90 degrees. Select every other link and replace with this rotated one... a chain... done.

          In such case, it will be better to do this way:

          And for making a rope, I'm sure we can do a good job with our same Chris Fullmer's Shape Bender.

            Try this, it's untested so give us a shout if it's broken.

              Hi Remus, 😉

              Something is wrong for me. "Simple Catenary Curve" opens and asks the number of segments (cool), but after validation, nothing happens..

                Sorry, it was a silly bug as i was distracted while writing it last night. Hopefully this version should work.

                  Sorry Remus,
                  Something is still wrong!
                  The Catenary curve is drawn so small that I can't zoom on it.

                  I have reloaded your first one to experiment FredoScale Strech tool to figure out something like my suspension bridge's ropes.

                  seems not bad. I have no mathematic element to say if that remains a Catenary Curve.

                      Hi REmus,
                      I just tryed your Tool "Simple Catenary Curve"
                      After the Dialog-box it seems that no Element was drawn.
                      where is the curve? 😮

                      Uli

                        Uli, its always drawn at the origin...you may need to zoom in close.
