Model.morphmapedgestosurfaceoffset

Model.morphmapedgestosurfaceoffset(user_mark_id, collection, use_symmetry, use_constraints, project, vector, number_of_mid_handles, offset)

Projects the handles on the marked morph volume edges to the surfaces on the mark along the specified vector, surface normal, or normal to any attached shell elements (unusual for morph volume edges).

Parameters:

• user_mark_id (int) – The ID of the user mark containing the morph edges. Valid values are 0-3.

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

• use_symmetry (int) –

  0 - Do not use symmetry links

  1 - Use symmetry links

• use_constraints (int) –

  0 - Do not use constraints

  1 - Use constraints

• project (int) –

  0 or 10 - Project along vector defined by vector_id

  1 or 11 - Project normal to surfaces

  2 or 12 - Project normal to attached shell elements

  If offset is non-zero, the offset will be measured from the closest point on the surfaces for values of 0, 1 and 2. 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.

• number_of_mid_handles (int) –

  -1 - Do not change the handles on the edges

  0 - 5 - Update the number of mid-handles on the edges to this number

• offset (double) –

  The distance to offset nodes from the target.

  The offset will be measured from the closest point on the surfaces 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.

Examples

Map edges on user mark 0 to a surface along a vector with offset of 1.2 and leaving the handles unchanged

import hm
import hm.entities as ent

model = hm.Model()

model.morphmanageedgemark(edge_id=0, user_mark_id=0, mode=3)
model.morphmanageedgemark(edge_id=2, user_mark_id=0, mode=1)
model.morphmanageedgemark(edge_id=4, user_mark_id=0, mode=1)

model.morphmapedgestosurfaceoffset(
    user_mark_id=0,
    collection=hm.Collection(model, ent.Surface, [1]),
    use_symmetry=1,
    use_constraints=1,
    project=0,
    vector=[1.0, 0.0, 0.0],
    number_of_mid_handles=-1,
    offset=1.2,
)
model.morphmanageedgemark(edge_id=0, user_mark_id=0, mode=3)

Map edges on user mark 1 to a surface along the surface normal with 3 mid-handles per edge

import hm
import hm.entities as ent

model = hm.Model()

model.morphmanageedgemark(edge_id=0, user_mark_id=1, mode=3)
model.morphmanageedgemark(edge_id=2, user_mark_id=1, mode=1)
model.morphmanageedgemark(edge_id=4, user_mark_id=1, mode=1)

model.morphmapedgestosurfaceoffset(
    user_mark_id=1,
    collection=hm.Collection(model, ent.Surface, [1]),
    use_symmetry=1,
    use_constraints=1,
    project=1,
    vector=[1.0, 0.0, 0.0],
    number_of_mid_handles=3,
    offset=0.0,
)
