ObjectContextManager Class

[Ertqwa]

Hello Forum,

I use the ObjectContextManager class to manage annotation scales.

objObjectContextCollection = objDatabase.ObjectContextManager.GetContextCollection("ACDB_ANNOTATIONSCALES");

AcDbObjectContextManager:

Exposes the collection of context types supported by the drawing. Each AcDbDatabase exposes an AcDbObjectContextManager which can be used to register, unregister, and enumerate custom context collections.

Unfortunally I can't find much information about this class. Can anyone give me some information about what a custom context collection is inside AutoCAD, and what kinds are there? Which strings besides "ACDB_ANNOTATIONSCALES" can be used in GetContextCollection()?

Thank you for your time.

Thank you for your response, but that was not my question.

The ObjectContextManager is currently only used for Annotation Scaling. However, it was designed to be a generic context object API, meaning that you can create your own Object Context data that utilizes this same object model.
