`getFeatures` (self)	Returns a list of all features of ShapeVariable.

Example

from hwx import inspire

model = inspire.newModel()
part = inspire.PolyNURBS.createBrick(x=1, y=2, z=3)
featurePoints = part.getFeatures(inspire.FeaturePoint)

# select existing cage points, allowing them to move in 
# a specified direction during optimization
sv1 = inspire.ShapeVariable(
{featurePoints[0]: [0, 0, 1], featurePoints[1]: [0, 1, 0]}
)

# To allow these cage points to move in different directions
# we must create multiple shape variables.
sv2 = inspire.ShapeVariable(
{featurePoints[0]: [0, 1, 0], featurePoints[1]: [0, 0, 1]}
)

property features#: A list of all features of ShapeVariable.

getFeatures()#: Returns a list of all features of ShapeVariable.

property pointDirections#

A dictionary representation of each FeaturePoint direction

Returns:: dict[FeaturePoint, math.Vector]
