To modify splines created with Create > Spline, you must first Explode the spline. Click Edit > Splines > Explode. After you exit the Explode dialog box, the Transform Copy dialog appears. Use the Transform Copy dialog to create the new spline a different color, or in a different layer. Then when you use Edit > Splines > Node to edit the new spline, use Masks or Layers to hide the old spline.
Analyze
Select a parametric spline to display a window that indicates the location and tangent vector information.
Move Node
Move a node to another location.
Tangent Vector
Change the direction of a tangent vector by indicating a new location for the tangent vector to point towards.
Line Tangent
Create a line that represents the tangent
vector at the spline node selected. The length of the line created equals
the magnitude of the tangent vector.
Splines can be thought of as having a directional quality that is indicated
by the direction of their tangent vectors.
Magnitude
Change the magnitude of a tangent vector to increase or decrease its effect on the spline.
Example, Magnitude
|
Original spline |
Magnitude doubled |
Magnitude reduced |

Copy Tangent Vector
Assign the direction of a tangent vector at one spline node to another spline node.
This does not copy the magnitude.
Copy Magnitude
Give one tangent vector the same magnitude value as another simply by clicking the nodes.
Untrim Yes / No
Click Untrim to change from Untrim Yes to Untrim No. While set to Yes, any trimmed spline selected will be temporarily untrimmed. The spline will return to its trimmed state when this is set back to No, when another spline is selected, or when you exit the spline editing menus.
