Model.morphbeziershape

Model.morphbeziershape(dcollection, ecollection, shapeid, sym, con, vvec, mag, type, meth, umark)

Create polynomial or spline based shapes for handles on the domains on the collection.

Parameters:

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

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

• shapeid (int) – The ID of the shape.

• sym (int) –

  0 - Do not use symmetry

  1 - Use symmetry

• con (int) –

  0 - Do not use constraints

  1 - Use constraints

• vvec (hwTriple) – The hwTriple object defining the vector. User can also supply a Python list of three doubles.

• mag (double) – Magnitude of perturbation

• type (int) –

  1 - Use vector for handle perturbations

  2 - Use element normals for handle perturbations

  3 - Use shape for handle perturbations

• meth (int) –

  0 - Polynomial

  1 - Spline

• umark (int) –

  0 - Use all elements to determine normals

  1 - Use elements on ecollection to determine normals

Example

A shape is created for each handle on each domain on the collection using the selected type to determine the perturbations

import hm
import hm.entities as ent

model = hm.Model()

model.morphbeziershape(
    dcollection=hm.CollectionByInteractiveSelection(model, ent.Domain),
    ecollection=hm.CollectionByInteractiveSelection(model, ent.Element),
    shapeid=12,
    sym=0,
    con=1,
    vvec=[1.0, 0.0, 0.0],
    mag=5.0,
    type=3,
    meth=1,
    umark=0,
)

Note

If type is 1 or 2, mag will be used as the magnitude of the handle perturbations. If type=3, the perturbations on the shape will be used.

If symmetry is used, all handles linked to marked handles by symmetry will also be perturbed. If constraints are used, they will be applied to the perturbations.
