Thanks, that's great. I'm not up to the C++ code but I've hacked [this demo](https://jsfiddle.net/flywire/ph4cfavd/) from [here](http://jsxgraph.uni-bayreuth.de/wiki/index.php/B-splines): > The points are connected by a cubic B-spline curve (i.e. order=4). ...

Hmm, the demo also calculates a line for 2 points so clearly they are using whatever they can to interpolate between points. It seems reasonable to extend spline to use...

I don't understand the concepts well enough to understand your communication so I can't confirm anything. https://jsxgraph.org/docs/symbols/JXG.Math.Numerics.html#.bspline > Computes the B-spline curve of order k (order = degree+1) through a...

[ Received by email ] > Could you guide us with the 3-point open B-spline implementation in https://librecad.org/ ? LibreCad currently requires a minimum of 4 points but https://jsxgraph.org/docs/symbols/JXG.Math.Numerics.html#.bspline works...

Quick and dirty conversion needs testing: https://github.com/flywire/LibreCAD/tree/dark-mode/librecad/res/icons/dark-mode

[Reference example](https://github.com/executablebooks/sphinx-copybutton/issues/185#issuecomment-1319144019). btw Can a final character be added to copied content?

Example at https://sphinx-copybutton.readthedocs.io/: ```py >>> a = 2 >>> print(a) 2 >>> >>> b = 'wow' >>> print(b) wow ``` copy/paste gives: ```py a = 2 print(a) b = 'wow'...
