 It contains and manages a spline that can be edited using [[layout-tool]].

+===== Controls =====
+==== Presets ====
+This pop-down allows you to store and retrieve splines using our [[tools:presets|]].
+==== Closed ====
+Determines if the spline is closed (a loop) or open.
+==== Information Display ====
+Currently only shows the number of knots in the spline.
+==== Use Defaults ====
+If enabled, the spline will use the defaults defined in the [[prefs]] to display and evaluate the spline.
+You can use custom values for this spline by disabling this option and changing the following values.
+==== Evaluation Steps ====
+The number of cached values per span that are used to compute the orientation along the spline.
+If you find the orientation to be "jaggy", increase this value.
+These are also used to compute the values required for [[tools:s-tk:displacement-node|]] and [[tools:s-tk:proximity-node|]].
+==== Selected Steps ====
+This is used when the spline is selected and drawn into a viewport.
+The value is number of lines drawn in the layout viewport per span to approximate the shape of the spline. The higher the value, the smoother the viewport representation is.
+However, a larger value also takes longer to draw and uses a bit more memory.
+==== Deselected Steps ====
+This is used when the spline is not selected and drawn into a viewport.
+The value is number of lines drawn in the layout viewport per span to approximate the shape of the spline. The higher the value, the smoother the viewport representation is.
+However, a larger value also takes longer to draw and uses a bit more memory.
+This value can be quite low if you have many splines in your scene and the ones you don't have selected don't have to be as precise.
+==== Open Spline Prefs...====
+Open the [[prefs]]
+==== Shapes ====
+As of October 2019, shapes are now supported as well. The controls in the Shapes tab allow you to solo to the shape selected in the list. You can also access the
+Progress envelope via this tab.
+Details on editing shapes are available here: [[tools:s-tk:layout-tool#shape_animation|"Spline Edit: Shape Animation"]]
