Start and End Condition MenuKeyCreator \ Create \ Spline \ Start-and-End-Condition-Menu
The Start and End Condition Menu appears in the Conversation bar frequently throughout spline creation. You can choose how to set the tangent vector at the end points of 2D and 3D splines to control the spline's shape. This menu does not appear with the Helical, 2D Closed, or 3D Closed options.
Automatically sets a curvature of zero to the appropriate end of the spline. This is the same as attaching the spline to the end point without applying any external forces. The ends are free.
This option specifies a tangent vector at a spline end point with two indicated positions.
End of Entity
This option specifies a tangent vector by using the tangency at the end of any existing curve, except circles.
This option allows you to enter the X and Y vector components, which determine the slope and magnitude of the tangent vector.
NOTE: If you set the View/World switch to View under Edit>Settings from the pull-down menu, the vector components are relative to the view coordinate axes. If you set it to World, the vector coordinates are relative to the world axes.
Determines the direction of a tangent vector using the entered angle between the tangent vector and the positive X axis. Angle only appears on the Start/End Condition Menu when you create a 2D Open or 2D Auto spline.
NOTE: A temporary marker is placed at the appropriate end of the spline.
