ElementSet

class compolyx.ElementSet(graph, obj=None, parent=None)

Element set class.

• Exemplary usage:

  >>> m=db.models.values()[-1]
  >>> eset=m.element_sets['DECK']
  >>> eset.modify(op='none')
  >>> eset.modify(op='new', element_labels=[1,2,3,4])
  >>> eset.modify(op='add', element_sets=[ m.element_sets['Deck_layup-1'] ])
  >>> eset.modify(op='intersect', x=[-6.5,-5.5])
