IsUpToDate

This function returns if an instance has geometry derived and if this geometry is still up-to-date. It could return false if geometry has never been updated or in case a property has been updated, or a (recursively) related instance has an updated property since last calculation of geometry.

Property owlInstance

Size: 64 bit / 8 byte (value)
The handle to the specific instance in the design tree. The instance handle is static within one open model but is most probably different when the same instance is opened in another model. The instance is always exactly of one unique class.
