How to draw a curve (spline) in 2D CAD
The curve tool draws a smooth spline through the points you tap. Use it for garden borders, paths, organic shapes and anything that is not a straight line or a true arc.

- Tap points along the curveTap each point the curve should pass through. It smooths itself as you add points.
- FinishTap the last point again, or tap ✓, to finish the curve.
Tips
- More points give you more control; fewer points give a smoother curve.
- Curves can be dimensioned with an arc length dimension.
- For a true circular curve, use the arc tool instead.
Questions
Can I trim a curve?
Dragging the trim tool across a curve removes the whole curve. Lines, arcs, circles and ellipses are cut back to the crossing.
