Sometimes, it is useful that the tangents of a Beziere spline are on the same line. Equal tangent direction doesn't mean that the tangents look into the same direction it just means that they are on the same line passing through their shared control point.

Modes
The equal tangent direction tool is available in all modes. Note that it makes most sense to use it in point mode since you can only see the control points and tangents in point mode. This spline tool only works on raw spline objects.

• 
  To use the equal tangent direction tool, you first have to select the control points of the spline whose tangents should be on the same line. Once you've made your selection call the menu command "ToolsSplineEqual Tangent Direction". The tangents of all selected control points will now be repositioned so that the second tangent of a control point is on the same line as the first tangent of the control point. If no selection has been made the command performs on all tangents.
