  • 'U': Unselect a set from the current set.

return_selectedbool, optional

Return the keypoint numbers selected. Optional, and can be disabled for performance. Default False.

Returns:
np.array

Numpy array of keypoint numbers if return_selected=True.

Return type:

Examples

Create a new selection of keypoints [1, 5, 10]

>>> mapdl.geometry.keypoint_select([1, 5, 10])

Create a new selection of keypoints from 1 through 20

>>> mapdl.geometry.keypoint_select(range(1, 21))

Unselect keypoints 1 through 20

>>> mapdl.geometry.keypoint_select(range(1, 21), sel_type='U')

Append to an existing selection of keypoints

>>> mapdl.geometry.keypoint_select([1, 2, 3], sel_type='A')

Reselect from the existing selection of keypoints

>>> mapdl.geometry.keypoint_select([3, 4, 5], sel_type='R')

Select no keypoints

>>> mapdl.geometry.keypoint_select(None)

Select all keypoints

>>> mapdl.geometry.keypoint_select('ALL')
