When you use to create an object in that contains a lot of information, such as a feature, it is important to be able to set up all of that information before adding the object to the database. The object-oriented style of does not allow explicit access to the contents of such a structure, however. Instead, you must use a special workspace object that is allocated and filled by the application using functions provided for that purpose.

The “workspace” is a memory area in that contains data structures not yet part of the design database.

The workspace object is identified by a handle that contains the address of the memory for the object, which is therefore similar to an OHandle. To distinguish this from handles that refer to objects in the database, such handles are called workspace handles (WHandles).
