=== Creating and editing instances ===
----
# Create a new metaclass via „Derive new object“ from the context menu
# Open the control “Object Editor”
# Save the changes
The system creates a new instance of “CUSTOMMETACLASS” and sets the “INHERIT” property to the metaclass the context menu was opened at. New derivates can be created for any system metaclasses as “BASECLASS”, “REFERENCE”, “SELECTIVELIST”, … etc.
