# isrenderobj

> Returns whether the value is object with the Drawing object type. This is a methods check only; it does not check whether the underlying Drawing object is still active, tracked, or destroyed. the Drawing API registers this API only when the required rendering environment is active is true; when that check is false, the initializer returns before creating these globals.
