Unfortunately, hyperbola is not fully implemented. We have most components ready, by missing the GUI support for creation and the actual rendering (drawing the curves), clearly the most important parts are missing from the user perspective. Any help is welcome.

For parabola support, you can actually get it by the spline Points (degree=2).

Using elliptical arcs to approximate a hyperbola is not easy.

For approximation, you can try the plot equation plugin, then you have the freedom to draw a hyperbola

Hi,
what would be an easy way to draw a hyperbola in LibreCAD.
Can it be done by modifying an ellipse?
Thanks
