Model.geom_extrude#

Model.geom_extrude(method, node_list=s_defaultEntityList, locations=hwDoubleList(), guide_list=s_defaultEntityList, vector=hwTriple(0.0, 0.0, 0.0), distance=0.0, frame='tangent', reverse_dir=False)#

Creates surfaces by extruding nodes or locations along guide lines or along a vector.

Parameters:

  • method (hwString) –

    The extrusion method. Valid values are:

    along_line - Extrude nodes or locations along lines.

    along_vector - Extrude nodes or locations along a vector

  • node_list (EntityList) – The list of entity objects representing the source nodes to extrude.

  • locations (hwDoubleList) – The list of x, y, z coordinates defining the source locations to extrude.

  • guide_list (EntityList) – The list of entity objects representing the guide lines. Valid for method="along_line".

  • vector (hwTriple) – The vector x, y, z components defining the extrusion direction. Valid for method="along_vector".

  • distance (double) – The extrusion distance. Valid for method="along_vector".

  • frame (hwString) – The extrusion frame. Valid values are fixed, tangent, and frenet. Valid for method="along_line".

  • reverse_dir (bool) – The flag to use the reverse direction. Valid for method="along_line".

Example#

Extrude locations (-28.0 -61.0 -6.0), (23.0 -43.0 0.0), (73.0 -43.0 0.0) along vector (0.0 0.0 1.0) by distance 57.0#
import hm
import hm.entities as ent

model = hm.Model()

model.geom_extrude(
    method="along_vector",
    locations=[-28.0, -61.0, -6.0, 23.0, -43.0, 0.0, 73.0, -43.0, 0.0],
    vector=[0.0, 0.0, 1.0],
    distance=57.0
)
Extrude nodes ID 5, 6, 7, 8 along lines 10, 11, 12 without reversing the direction in tangent frame#
import hm
import hm.entities as ent

model = hm.Model()

model.geom_extrude(
    method="along_line",
    node_list=[ent.Node(model, id) for id in [5, 6, 7, 8]],
    guide_list=[ent.Line(model, id) for id in [10, 11, 12]],
    frame="tangent",
    reverse_dir=False
)
