Hi Ed, unfortunately I don't think it is possible currently for a script to use interactiveViewChange() in this way.

The way view.interactiveViewChange() works currently is that it posts a message and then lets the current call stack unwind and doesn't start the view change loop until when the message is processed.

I will add in an optional 2nd parameter to interactiveViewChange() to make it go into its modal loop immediately rather than posting a message, so in v5 you will be able to do it like this without setting up your own event loop:

moi.ui.mainWindow.viewpanel.getViewport('3D').interactiveViewChange('zoomarea', true);

Thanks Michael - I'll use the Continue button for now.

Looking forward to Ver 5.

Hi Ed,

Checking moi.majorVersionNumber might be helpful?

    if ( moi.majorVersionNumber < 5) {
        moi.ui.mainWindow.viewpanel.getViewport('3D').interactiveViewChange('zoomarea');
	
	while (1)
	{	
	    moi.ui.commandDialog.waitForEvent();
	    
	    if ( moi.ui.commandDialog.event === 'continue' ) {
                return;
            }
	    
	}
    } else
        moi.ui.mainWindow.viewpanel.getViewport('3D').interactiveViewChange('zoomarea', true);

Good idea Larry - We'll do.
