### *class* compolyx.PropertySet(gil\_wrapper, parent\_=None, name\_='')

Python PropertySet class

This class wraps GIL-functionality and adds Python-UI utilities to all material PropertySets (Engineering Constants, Stress Limits, etc.).

### Examples

```pycon
>>> model = db.active_model
>>> Eglas = model.material_data.materials['E-Glas']
>>> Eglas_strain_limits = Eglas['strain_limits']
>>> print Eglas_strain_limits.property_names

```

\[‘eXt’, ‘eXc’, ‘eYt’, ‘eYc’, ‘eZt’, ‘eZc’, ‘eSxy’, ‘eSxz’, ‘eSyz’, ‘effective\_strain’\]

```pycon
>>> Eglas.update()
>>> Eglas_Xt = Eglas_strain_limits.query('eXt', {'UserVar1' : 0.3, 'Temperature' : 65.7})

```
