Model.normalsadjustbynodes

Model.normalsadjustbynodes(collection, node_collection, size, display)

Adjusts the normals of 3D elements according to nodes of a solid element.

Parameters:

• collection (Collection) – The collection containing the input entities to adjust normals for. Valid entities are elements and components.

• node_collection (Collection) – The collection containing the node entities that define the selected solid element face.

• size (double) – Specifies the size of the normal graphics to be drawn. If set to zero, the vector is drawn at 10% of the screen size.

• display (int) –

  0 - Display all elements normals upon function completion.

  1 - Display only adjusted element normals upon function completion.

Example

Adjust the normals of elements with IDs 1 - 10 based on faces defined by nodes with IDs 5 , 7 and 9 use a display size of 10.0

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)

model.normalsadjustbynodes(
    entity_type=ent.Element,
    collection=elements_collection,
    node_collection=(model, ent.Node, [5, 7, 9]),
    size=10.0,
    display=1,
)
