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.
- progress_barbool,
- 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() PolyData (0x7f2f8c132040) N Cells: 88 N Points: 90 X Bounds: 0.000e+00, 1.000e+00 Y Bounds: 0.000e+00, 1.000e+00 Z Bounds: 0.000e+00, 5.000e+00 N Arrays: 3
