Model.geom_simplify#

Model.geom_simplify(collection, primitive_type='box', cover='per_body', simplify=0, delete_original=0, dest_comp='current', comp_name='')#

Simplifies the general shape of the input selection by fitting a box, a cylinder, or a convex-hull.

Parameters:

  • collection (Collection) – The collection containing the entities to fic the general shape.

  • primitive_type (hwString) – The type of shape used for fitting. Valid values are box (default), cylinder, and convex_hull.

  • cover (hwString) –

    Applicable only for input entity type surfaces. Valid values are:

    per_body - Input surfaces are grouped into connected set of surfaces and individual fittings are done per group. (default)

    all - Fitting is performed for all input surfaces at once.

  • simplify (int) – Valid only for primitive_type="convex_hull". If set to 1, the shape is further simplified by combining faces together, or removing small size faces. The new shape will not cover the input as tightly as the non-simplified convex hull. Valid values are 0 (default) or 1.

  • delete_original (int) – Applicable only if the input entities are surface. Valid values are 0 (default) and 1. If set to 1, the input surfaces are deleted after successful fitting.

  • dest_comp (hwString) –

    Valid values are:

    current - New entities are created in the current component. (default)

    original - New entities are created in the component of the input solid.

    named_comp - New entities are created in the named component specified in comp_name. If a component with the given name does not exist, a new component is created.

  • comp_name (hwString) – The name of the component in which user wants the result entities to be created. (default = “”)

Example#

Fitting cylinders to a set of surfaces with IDs 20-50, in a component named “CYLINDER FITTING”, with a cylinder for each connected set of input surfaces#
import hm
import hm.entities as ent

model = hm.Model()


# Creating a collection that contains the surfaces
filter_surfaces = hm.FilterByEnumeration(ent.Surface, list(range(20, 51)))
surface_collection = hm.Collection(model, filter_surfaces)

model.geom_simplify(
collection=surface_collection,
cover="per_body",
dest_comp="named_comp",
comp_name="CYLINDER FITTING",
)
