Object User Data

Object User Data

Every object in KernelCAD model keeps a user (application)-defined 32-bit integer value and an arbitrary length string called Object User Data.

The integer is not used by the Kernel CAD component itself. It is designed to store any user/application defined value. Normally the number is used to link the object to an external data in the application like object description. The Object User Data can also be used to link the object to its data in User Data Table.

The string is also used as Layer Name of the object in calls to methods of ILayers to show/hide objects with the same layer name. This is the only place, apart from IUserData.Get/SetLayerName, where the component accesses the string in read-only manner.

The two properties can be accessed via IUserData interface.
