Model.rotatemark

Model.rotatemark(collection, plane_normal, plane_base, angle)

Rotates a selection of entities about a plane.

Parameters:

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

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

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

• angle (double) – The angle to rotate in degrees.

Example

Rotate the elements with IDs 56 and 57 about the z axis ( 30.0 degrees ) with an origin of ( 3.0,4.0,0.0 )

import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection that contains the elements to rotate
element_collection = hm.Collection(model, ent.Element, [56, 57])

model.rotatemark(
    collection=element_collection,
    plane_normal=[0.0, 0.0, 1.0],
    plane_base=[3.0, 4.0, 0.0],
    angle=30.0,
)
