When you use Creo TOOLKIT to create an object in Creo Parametric 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 Creo Parametric database. The object-oriented style of Creo TOOLKIT 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 Creo TOOLKIT application using functions provided for that purpose.

The “workspace” is a memory area in Creo Parametric 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 Creo Parametric database, such handles are called workspace handles (WHandles).
