Change Curve Direction

Used to reverse an element's (line, line string, arc, ellipse, complex chain, complex shape, curve, or B-spline curve) direction.

You can access this tool from the following:



  • Ribbon: Modeling > Curves > Curve Utilities > Change Curve > Direction
  • Toolbox: Modify Curves

When this tool is used with a Selection Set, the different elements can be changed by clicking on the handle. All the elements can be changed by holding the <Ctrl> key and clicking on a handle.

When placed, an open element's direction is from its start point (the first point defined) to its end point.

An element's direction is significant when:

  • It is labeled with the Element Dimensioning tool using the Label Line mode.
  • A view is rotated to align with it.
