extract_geometry¶

UnstructuredGrid.extract_geometry(progress_bar=False)¶

Extract the outer surface of a volume or structured grid dataset.

This will extract all 0D, 1D, and 2D cells producing the boundary faces of the dataset.

Note

This tends to be less efficient than extract_surface().

Parameters

progress_barbool, optional: Display a progress bar to indicate progress.

Returns

pyvista.PolyData: Surface of the dataset.

Examples

Extract the surface of a sample unstructured grid.

>>> import pyvista
>>> from pyvista import examples
>>> hex_beam = pyvista.read(examples.hexbeamfile)
>>> hex_beam.extract_geometry()
