Model.draglinetoformsurface#

Model.draglinetoformsurface(linelist, entitylist, direction_vector, distance, solid_stitch=0)#

Drags trimmed lines 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 dragged surface for the automesher to use under the mesh without surface option.

Parameters:

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

  • entitylist (EntityList) – The list node entities which lie on the lines in the linelist, which will be used to trim the line during surface creation.

  • direction_vector (hwTriple) – The direction vector to drag the lines.

  • distance (double) – The distance to drag the lines.

  • solid_stitch (int) –

    0 - Created surface will not be stitched to a solid.

    1 - Created surface will be stitched to a solid.

Example#

Drag the lines with IDs 1, 2, trimmed by the nodes with IDs 29 and 30, -100.0 units in the direction of the y-axis, create a surface but no elements#
import hm
import hm.entities as ent

model = hm.Model()

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

Line1 = ent.Line(model, 1)
Line2 = ent.Line(model, 2)

node1 = ent.Node(model, 29)
node2 = ent.Node(model, 30)

model.draglinetoformsurface(
    linelist=[Line1, Line2],
    entitylist=[node1, node2],
    direction_vector=[0.0, 1.0, 0.0],
    distance=-100.0,
