yes, we would like to have spline and spline interpolation curves, i.e., spline curves to pass given points.

OK, thanks. I've found LibreCAD as a great system. Now, once I managed to build the application, I plan to implement some new sort of splines, which would go through the defined points and which would be possible to divide and draw with patterned line style. This is, I believe, quite a hard task for the current B-splines implementation. The idea behind is to approximate intersection of two cylinders, for example. I will create a new thread if I make any progress.
