Parameters:

meshpyvista.PolyData

Surface mesh to convert.

Returns:

OCP.TopoDS.TopoDS_Compound

Faceted compound.

Raises:

pyvista_cad.OptionalDependencyError

Examples

Build a faceted OCCT compound from a PyVista sphere (requires the [step] extra):

>>> import pyvista as pv
>>> from pyvista_cad import to_topods
>>> shape = to_topods(pv.Sphere())
>>> type(shape).__name__
'TopoDS_Solid'
