Hello Mac1,

The angles will be smooth much like a sine wave so kinking would not be an issue. Yes it is a flexible track that allows to you bend the shape you would like within a certain maximum radius.

Thanks Gilles I'll give that a shot.

Hi Mac1, the bar is rather thin ~3/16 think and .5" high and rather pliable (monorail track for track lighting). I figured there would be some spring back but I was just going to bend it with the form and then modify the form as needed to deal with the spring back. Thanks for the input.

Thanks Mitcorb.

I think fredoScale will do what I need. It is hard to illustrate what I am after but what I am trying to do is bend a 4' metal bar around a curved form and I am try to use sketchup to figure out how to cut the wood template around which I will bend the metal. So I was starting out with a 4' long polyline and then using f-spline but that only fixes the ends so after I bend it the total length of the polyline increase. I was wondering if there was something that fixed the entire length of the polyline and not just the end. I hope this makes sense. Thanks for pointing me to FredoScale.

Hello,

Is there a way to make a spline that does not stretch? I need to bend a 4' bar along a spline so I need it to maintain its length.

Thanks for any help.
