Model.linedragelements#

Model.linedragelements(collection, guidelines, guideendpoints, plane_normal, plane_base, ondrag, biasstyle, biasing, using_default_vector)#

Creates a mesh by dragging elements along a line.

Parameters:

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

  • guidelines (EntityList) – The line entity representing the guide line

  • guideendpoints (EntityList) – The list containing the node entities which will be used to segment the guide line.

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

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

  • ondrag (int) – The number of elements to be created along the drag.

  • biasstyle (int) – The type of biasing to use.

  • biasing (double) – The biasing intensity value.

  • using_default_vector (int) –

    0 - Use plane normal vector

    1 - Use default normal vector

Example#

Drag linearly the element with ID 100, along the guide line with ID 2 and guide nodes with IDs 2154, 2155 with plane with normal along y-axis and create 4 elements#
import hm
import hm.entities as ent

model = hm.Model()

model.linedragelements(
    collection=hm.Collection(model, ent.Element, [100]),
    guidelines=[ent.Line(model, 2)],
    guideendpoints=[ent.Node(model, 2154), ent.Node(model, 2155)],
    plane_base=[850, 150, 470],
    plane_normal=[0, 1, 0],
    ondrag=3,
    biasstyle=0,
    biasing=1,
    using_default_vector=0,
