A ShapePath represents one key of spline data for a shape.

Name	Description
bounds	the bounding box
clockwise	True if clock-wise
closed	True if closed (read/write)
flags	a List of Integers representing the flags for each control point
numPoints	the number of control points
points	a List of tuples containing the control point information
range	a Tuple (start, end) with the t-value range for this shape type
type	the Shape Type

Name	Description
clone()	returns a copy of the path
evalDerivative(t)	evaluate the derivative at t
evalPoint(t)	evaluate the point at t
interpolate(path, t)	generate and return a new ShapePath by interpolating with `path` using t
selected(index)	True if the control point at index is selected
transform(Matrix, selected=False)	transform all (or just the selected) points by the Matrix

Name	Description
Flag_Selected	The control point is selected
Flag_Tagged	The control point is tagged

+|clone()
-|Constructor - Initializes the base class. The menu can be listed separately or prefixed to the label with the '<nowiki>|</nowiki>' character.
+|returns a copy of the path
 |-
-|available()
+|evalDerivative(t)
-|Should return True (the default) if the Action is available. The Action should examine the current state in this method and assert (with an optional error message) that conditions are good for execution.
+|evaluate the [[Point3D|derivative]] at ''t''
 |-
-|execute(path=None)
+|evalPoint(t)
-|Called to execute the Action. UI Actions should be undoable. Importer/Exporter actions are passed the path to the file to operate on.
