Model.morphmaptotacitvecoffset#

Model.morphmaptotacitvecoffset(collection_nodes, collection_handles, collection_elems, use_symmetry, use_constraints, project, vector, mode, offset)#

Maps nodes to, or offset from, a collection of elements using the temporary shape created by Model.morphmaptshp() and Model.morphmaptshpedge() as a guide. Selected handles can optionally follow behind the morphing operation.

Nodes can be projected on to the target elements along a vector, normal to the target elements, or projected normal to the elements touching the nodes.

Parameters:

  • collection_nodes (Collection) – The collection containing the entities.

  • collection_handles (Collection) – The collection containing the entities.

  • collection_elems (Collection) – The collection containing the entities.

  • use_symmetry (int) – 0 - Do not use symmetry (only option)

  • use_constraints (int) –

    0 - Do not use constraints

    1 - Use constraints

  • project (int) –

    0 or 10 - Project along vector defined by vector

    1 or 11 - Project normal to the elements on the collection

    2 or 12 - Project normal to shell elements touching nodes

    If offset is non-zero, the offset will be measured from the closest point on the elements for values of 0 and 1. The offset will be measured along the projection vector or normal for values of 10, 11 and 12.

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

  • mode (int) –

    0 - If Model.morphmaprecalc() has been used to calculate new influences

    1 - To recalculate new influences inside this function

  • offset (double) –

    The distance to offset nodes from the target.

    The offset will be measured from the closest point on the elements for values of project of 0, 1, and 2.

    The offset will be measured along the projection vector normal for values of project of 10, 11, and 12.

Example#

Map all nodes to elements with IDs 1-100 with an offset of 1.2 when not using Model.morphmaprecalc()#
import hm
import hm.entities as ent

model = hm.Model()

model.morphmaptotacitvecoffset(
    collection_nodes=hm.Collection(model, ent.Node),
    collection_handles=hm.CollectionByInteractiveSelection(model, ent.Handle),
    collection_elems=hm.Collection(model, list(range(1, 101))),
    use_symmetry=0,
    use_constraints=1,
    project=2,
    vector=[1.0, 0.0, 0.0],
    mode=1,
    offset=1.2,
