It creates quadrilateral splines such as trapezoids and parallelograms — simple four-sided outlines as node geometry. This Node creates various 4-sided spline geometries, such as trapeziums or parallelograms. ![Image: R25_4side.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/R25_4side.jpg)\ The different types of spline shapes that can be created by this Node.
