1.2

Creates another instance of a "world" for Visual CADD™ to create or modify a drawing.

extern "C" WORLDHANDLE WINAPI VCNewWorld(HWND hWnd_);

function VCNewWorld(hWnd_: Smallint):Longint; stdcall;

Function NewWorld(ByVal hWnd_ As Long) As Long

hWnd - the hWnd handle for the object to be used as the new world.
Returns - a long representing a Visual CADD™ worldhandle.

Whenever the application needs to create a new drawing area, such as in an MDI window, Visual CADD™ needs to know the hWnd value for the object which is to contain the new drawing space. This creates a new environment for the drawing and exists entirely outside any other current drawings or worlds. The returned long is used by other Visual CADD™ API calls to reference which world the call be affecting.
