Dynamically Rotate Model View Example (C++ COM)

This example shows how to dynamically rotate a model view. It also shows you how to speed up the process by using the StartDynamics and StopDynamics calls.

RotateTheView(ISldWorks* m_pSldWorks)

{

 LPMODELDOC2 p_ModelDoc = NULL;

 LPMODELVIEW p_ModelView = NULL;

 HRESULT res = S_OK;

 // Retrieve the model document pointer

 res = m_pSldWorks->get_IActiveDoc2( &p_ModelDoc );  

 if( res != S_OK || p_ModelDoc == NULL )

  return;

  // Get the active view pointer

 res = p_ModelDoc->get_IActiveView(&p_ModelView);  

 if( res != S_OK || p_ModelView == NULL )

 {

  p_ModelDoc->Release();

  return;

 }

 int i;

 // Prepare view for rotation

 p_ModelView->StartDynamics();      

 for (i = 1; i < 100; i++)

 {

   p_ModelDoc->ViewRotateplusy();

 }

 // End dynamic rotation mode

 p_ModelView->StopDynamics();      

 // Repaint the screen

 p_ModelDoc->GraphicsRedraw2();      

 //Clean up

 p_ModelView->Release();

 p_ModelDoc->Release();

}
