ObjectGenerator class

DIObjGenerator COM class allows creation of instances of objects, which are not directly part of the rendered model. See also Object Array sample and Cannon sample.

DIObjGenerator  is an Object Generator, which allows creation of new objects. In COM terminology DIObjGenerator  is a Class Factory. It can be instantiated in COM-enabled development environments by using either its Class ID or Program ID (see below). Note that KernelCAD control does not have to be created in the application before creation of the object. 

In .NET environment DIObjGenerator can be created using standard new operator as (C# example):

       KernCADnet.DIObjGeneratorClass sect = new KernCADnet.DIObjGeneratorClass();

Actual name of the wrapper class might be different in different versions of the development environment. Refer to Object Browser in the project after adding a reference to the KernelCADnet component (See Patch Tutorial).

In C++ the DIObjGenerator can be instantiated by using its Class ID and call to CoGetClassObject() COM function. See  Cannon sample for details of implementation.

In native Visual Basic an instance of the class can be created using the Program ID and CreateObject() API as follows:

            Dim gener3D As Object

            gener3D = CreateObject("KERNELCAD.DIObjGenerator.1")

DIObjGenerator implements a single interface IDIObjGenerator, which can be obtained via call to CreateInstance() COM API in C/C++ or a cast in other languages.

Create method of IDIObjGenerator can be used to create new instance of objects. Types of objects, which can be created using IDIObjGenerator are listed in Object type enumeration.
