Model.linedraglinetoformsurface#

Model.linedraglinetoformsurface(sectionlinelist, sectionnodelist, draglinelist, dragnodelist, refplane_normal, refplane_base, using_default_vector)#

Drags a trimmed line along a trimmed line to create a surface, and optionally, prepares it for immediate use within the automesher. It can also identify a region in the shape of a line-dragged surface for the automesher to use under the mesh without surface option.

Parameters:

  • sectionlinelist (EntityList) – The list of line entities to be dragged.

  • sectionnodelist (EntityList) – The list of two node entities which lie on the lines in the sectionlinelist which will be used to trim the line during surface creation.

  • draglinelist (EntityList) – The list of line entities to drag along.

  • dragnodelist (EntityList) – The list of two node entities which lie on the lines in the draglinelist which will be used to trim the line during surface creation.

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

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

  • using_default_vector (int) –

    Flag that defines the type normal vector. Valid options are:

    0 - Use plane normal vector

    1 - Use default normal vector

Example#

Drag lines with IDs 3 and 4 along lines 2 and 1 use the given plane , create a surface but no elements#
import hm
import hm.entities as ent

model = hm.Model()

# The model.surfacemode(mode=4) directive tells HyperMesh not to pass the information
#  on to the automesher for element creation.
model.surfacemode(mode=4)

sectionline_list = [ent.Line(model, 3), ent.Line(model, 4)]
dragline_list = [ent.Line(model, 2), ent.Line(model, 1)]

model.linedraglinetoformsurface(
    sectionlinelist=sectionline_list,
    sectionnodelist=ent.Node.getentitylist(),
    draglinelist=dragline_list,
    dragnodelist=ent.Node.getentitylist(),
    refplane_normal=[0.0, 1.0, 0.0],
    refplane_base=[0.0, 0.0, 100.0],
