# contour

Contours surround strokes you draw with the Brush tool.

Brush strokes require more memory to store than do shapes you draw with the centerline tools: Polyline, Pencil, Ellipse or Rectangle.

- You can convert your brush strokes to centerlines to reduce the amount of memory required for storage (file size).
- You can also delete control points in contours to reduce the file size of your animation.
