Controls the display of 2D element ply normals.

Parameters:

  • ply_name (hwString) – The name of the ply to display normals for.

  • collection (Collection) – The collection containing the element entities whose normals are to be displayed. If empty, all plies in the specified ply are considered.

Example#

Turn on the display of normals for elements with IDs 1-10 in “Ply1”, at 10% screen size#
import hm
import hm.entities as ent

model = hm.Model()

# Creating a collection that contains the elements with IDs 1-10
filter_elements = hm.FilterByEnumeration(ent.Element, list(range(1, 11)))
elements_collection = hm.Collection(model, filter_elements)
