Model.reflectmarkwithoption#

Model.reflectmarkwithoption(collection, plane_normal, plane_base, option)#

Reflects a selection of entities about a plane.

Parameters:

  • collection (Collection) – The collection containing the entities to reflect.

  • plane_normal (hwTriple) – The hwTriple object defining the plane normal components used for the reflection. User can also supply a Python list of three doubles.

  • plane_base (hwTriple) – The hwTriple object defining the base point components of the plane used for the reflection. User can also supply a Python list of three doubles.

  • option (int) –

    0 - Maintain the z-axis of bar elements during reflection.

    1 - Maintain bar element connectivity during reflection.

Examples#

Reflect the element with ID 15 about a plane normal to the x-axis with its base at the origin by maintain the z-axis#
import hm
import hm.entities as ent

model = hm.Model()

model.reflectmarkwithoption(
    collection=hm.Collection(model, ent.Element, [15]),
    plane_normal=[1.0, 0.0, 0.0],
    plane_base=[0.0, 0.0, 0.0],
    option=0,
)
