JoinedCurve

JoinedCurve[{segment1, segment2, ...}] represents a curve consisting of connected segments.

Examples

Connected line segments:

Graphics[JoinedCurve[{Line[{{0, 0}, {1, 1}}], Line[{{1, 1}, {2, 0}}]}]]

With Bezier curves:

Graphics[JoinedCurve[{BezierCurve[{{0, 0}, {0.5, 1}, {1, 0}}], Line[{{1, 0}, {2, 1}}]}]]
