pyvista_cad.CadMultiBlockAccessor.split_by_label

CadMultiBlockAccessor.split_by_label(label_array='cad.label')

Combine the assembly, then split by per-cell label value.

Combines every leaf into one mesh and partitions it by the distinct values of the label_array cell-data array, one block per unique value. Value-based partition, not a pattern match.

Parameters:

label_arraystr, default: ‘cad.label’

Name of the per-cell array whose distinct values define the partition.

Returns:

pyvista.MultiBlock

One block per unique label value.

Parameters:

label_array (str)

Return type:

MultiBlock

Examples

>>> import numpy as np
>>> import pyvista as pv
>>> import pyvista_cad
>>> a, b = pv.Cube().triangulate(), pv.Sphere()
>>> a.cell_data['cad.label'] = np.array(['a'] * a.n_cells)
>>> b.cell_data['cad.label'] = np.array(['b'] * b.n_cells)
>>> parts = pv.MultiBlock([a, b]).cad.split_by_label()
>>> sorted(parts.keys())
['a', 'b']
