====== tool_image60 Curve ======

> Allow users to create curve by using this tool. Users can draw the curve directly, and do not have to use Segment Tool to draw a segment and then drag it into curve by using Curve Tool; allow users to move a group of control/regular points by entering desired value or by freehand, which improves the efficency of pattern-making.

===== Draw a curve as desired =====

> Select {{en:resources:pattern_tools_reference:tool_image60.png|tool_image60}} Curve Tool, left-click to draw a curve. Three points make a curve.

=== NOTE ===

  - Three points make a curve. Because the limition of points, the curve is not smooth enough, so users can add more points on the curve by using Add Point Tool to adjust the curve. > {{en:resources:pattern_tools_reference:tool_image62.png|tool_image62}}
  - Allow users to move the curve point to modify the bending of the curve. > {{en:resources:pattern_tools_reference:tool_image63.png|tool_image63}}

===== Move a group of curve point (control point) as desired =====

>   - Select the desired curve;
