Return Box Extents Example (C++ Dispatch)

This example shows how to return the box extents of assembly components.

NOTE: There is no checking to see if the components are suppressed.

 

void GetComponentExtents()

{

 LPDISPATCH  pDispatch;

 IModelDoc  ModelDoc;

 IConfiguration Configuration;

 IComponent  RootComponent;

 VARIANT   varChildren;

 SafeArray*  psaChildren;

 VARIANT   varBox;

 SafeArray*  psaBox;

 IComponent  Child;

 long   i, nChildren;

 double   extent[6];

 double   value;

 long   j;

 

 

 // Get the AssemblyDoc

 pDispatch = GetSOLIDWORKS()->GetActiveDoc();

 ModelDoc.AttachDispatch(pDispatch);

 if ( ModelDoc.GetType() == swDocASSEMBLY )

 {

 

  // Get the direct children of this assembly

  if ( (pDispatch = ModelDoc.GetActiveConfiguration()) != NULL )

  {

   Configuration.AttachDispatch(pDispatch);

 

   if ( (pDispatch = Configuration.GetRootComponent()) != NULL )

   {

    RootComponent.AttachDispatch(pDispatch);

 

    varChildren = RootComponent.GetChildren();

    psaChildren = V_ARRAY(&varChildren);

    SafeArrayGetUBound(psaChildren, 1, &nChildren);

    for ( i=0; i<=nChildren; i++ )   // Note Ubound 0 is 1 child

    {

     SafeArrayGetElement(psaChildren, &i, &pDispatch);

     Child.AttachDispatch(pDispatch);

   

     // Extract the extents from the components

     varBox = Child.GetBox(FALSE, FALSE);

     psaBox = V_ARRAY(&varBox);

     SafeArrayLock(psaBox);

     for ( j=0; j<6; j++ )

     {

      SafeArrayGetElement(psaBox, &j, (VOID *)(&(value)));

      extent[j] = value;

     }

 

     // Destroy the Box SafeArray

     SafeArrayUnlock(psaBox);

     SafeArrayDestroy(psaBox);

     Child.ReleaseDispatch();

    }

 

    // Destroy the children SafeArray

    SafeArrayDestroy(psaChildren);

   }

  }

 }

 

 return;
