Anotations

Scope note:

Forms or outlines consisting of a curved line that winds or meanders in multiple directions but does not cross or intersect itself. An example is when describing furniture pieces, the fronts of which are shaped in alternating concave and convex curves. For other features, such as arches or moldings, composed of flowing, wavelike curves, use "undulating." For features consisting of or bounded by curved lines in general use "curvilinear."
