Model.surfacesplinefrompoints#

Model.surfacesplinefrompoints(collection, options)#

Creates a spline surface using selected nodes or points as boundary conditions.

Parameters:

  • collection (Collection) – The collection containing the entities to use as input. Valid entities are nodes and points.

  • options (int) –

    Specifies options for creating the surface.

    Bit values are used and the value is calculated as (Bit0 + 4*Bit1). Valid Bit options are:

    Bit0 Surface trim mode. Valid values are:

    0 - Trim by parametric rectangle.

    1 - Trim by points boundary.

    Bit1

    Mesh stitching. Used to control the connectivity of the mesh created on the new spline surface in simultaneous meshing modes. Valid values are:

    0 - New mesh is not connected.

    1 - If Model.surfacemode() is set to 1, existing mesh nodes are used if new spline edges are stitched to those lines.

Examples#

Build a spline from the displayed points and do not connect mesh#
import hm
import hm.entities as ent

model = hm.Model()

model.surfacemode(mode=1)

model.surfacesplinefrompoints(
    collection=hm.CollectionByDisplayed(model, ent.Point), options=0
)
Build a spline from the displayed points and do not connect mesh#
import hm
import hm.entities as ent

model = hm.Model()

model.surfacemode(mode=1)
