Model.morphconstraintcreatearcrad

Model.morphconstraintcreatearcrad(scollection, acollection, type, name, plane_normal, plane_base, dptr, radius, bound, arc, color)

Creates a model type constraint based on the radius or arc length of an edge domain.

Parameters:

• scollection (Collection) – The collection containing the input shape entities.

• acollection (Collection) – The collection containing the entities used for radius measurement. Valid entities are nodes and lines.

• type (int) –

  0 - Measure radius or arc angle using domain

  1 - Measure radius or arc angle using axis

  2 - Measure radius or arc angle using line

  3 - Measure radius or arc angle using node

• name (hwString) – Name of morph constraint.

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

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

• dptr (Entity) – The domain entity of the edge.

• radius (double) – Constrained radius or arc angle.

• bound (int) –

  -1 - Greater than specified angle

  0 - Equal to specified angle

  1 - Less than specified angle

• arc (int) –

  0 - Radius

  1 - Arc angle

• color (int) – The color of the constraint. Valid values are 1 through 64.

Example

Create a model type constraint for the domain with ID 21 with the option of have the radius or arc angle measured in the plane of the domain , about an axis , about a line or about a node , and the option of have the radius or arc angle forced to be greater than , less than , or equal to the specified value .

import hm
import hm.entities as ent

model = hm.Model()

model.morphconstraintcreatearcrad(
    scollection=hm.CollectionByInteractiveSelection(model, ent.Shape),
    acollection=hm.CollectionByInteractiveSelection(model, ent.Node),
    type=0,
    name="radius",
    plane_normal=[1.0, 0.0, 0.0],
    plane_base=[0.0, 0.0, 0.0],
    dptr=ent.Domain(model, 21),
    radius=5.0,
    bound=0,
    arc=0,
    color=32,
)

Note

If arc=0, the radius will be constrained. If arc=1 the arc angle will be constrained.

The shapes on the collection will be used to force the model into compliance with the specified constraint if possible
