class TrimmedSurface(untrimmed_surface: Surface, outer_boundary: CompositeCurve3D, outer_boundary_para: CompositeCurve3D, outer_curve_on_parametric_surf_para: CurveOnParametricSurface, inner_boundaries: List[CompositeCurve3D] = None, inner_boundaries_para: List[CurveOnParametricSurface] = None, name: str = 'TrimmedSurface', construction: bool = False)

Bases: Surface

__init__(untrimmed_surface: Surface, outer_boundary: CompositeCurve3D, outer_boundary_para: CompositeCurve3D, outer_curve_on_parametric_surf_para: CurveOnParametricSurface, inner_boundaries: List[CompositeCurve3D] = None, inner_boundaries_para: List[CurveOnParametricSurface] = None, name: str = 'TrimmedSurface', construction: bool = False)

Parameters:

• untrimmed_surface (Surface)

• outer_boundary (CompositeCurve3D)

• outer_boundary_para (CompositeCurve3D)

• outer_curve_on_parametric_surf_para (CurveOnParametricSurface)

• inner_boundaries (List[CompositeCurve3D] or None)

• inner_boundaries_para (List[CurveOnParametricSurface] or None)

• name (str) – Name of the geometric object. May be re-assigned a unique name when added to a GeometryContainer

• construction (bool) – Whether this is a geometry used only for construction of other geometries. If True, this geometry will not be exported or plotted. Default: False

Methods

evaluate(Nt)
from_planar_boundary_curves(outer_boundary)
plot_surface(plot[, Nt])	Plots the trimmed surface using the pyvista library
to_iges(*args, **kwargs)	Converts the geometric object to an IGES entity.
transform(**transformation_kwargs)	Creates a transformed copy of the surface by transforming both the outer boundary in geometric space and the untrimmed surface.

Attributes

plot_surface(plot: Plotter, Nt: int = 100, **mesh_kwargs)

Plots the trimmed surface using the pyvista library

Parameters:

• plot – pyvista.Plotter instance

• Nt (int) – Number of points to evaluate on each boundary curve. Default: 100

• mesh_kwargs – Keyword arguments to pass to pyvista.Plotter.add_mesh

Returns:

The evaluated rational Bézier surface

Return type:

pyvista.core.pointset.StructuredGrid

to_iges(*args, **kwargs) → List[IGESEntity]

Converts the geometric object to an IGES entity. To add this IGES entity to an .igs file, use an IGESGenerator.

transform(**transformation_kwargs) → TrimmedSurface

Creates a transformed copy of the surface by transforming both the outer boundary in geometric space and the untrimmed surface. The parameteric trimming curves are left unmodified.

Parameters:

transformation_kwargs – Keyword arguments passed to Transformation3D

Returns:

Transformed surface

Return type:

TrimmedSurface
