[quote user="Paul Connelly"] Maybe you should describe why you feel you need to update the viewport[/quote]
I'm attempting to focus a view on a particular element. Here's where I'm setting the view origin & extent...
viewInfo.SetGeometry(elementCentre, elementDelta, rotation); viewGroup.SetViewInformation(viewInfo, nView); viewGroup.SaveChanges(); viewGroup.SynchViewDisplay(nView, false, true, false);
When I run the code I see no change in the view. If I update the view manually, I see the view focus on the element. My assumption is that I need to update the view after SynchViewDisplay().
