What is the difference between LayoutManager.CopyLayout and LayoutManager.CloneLayout ?
How they behave?
In ObjectARX there is an AcApLayoutManager.updateLayoutTabs() .
Is there a similiar function in .NET ?
As far as I can tell the only difference is that you can specify a placement index using the clone method, whereas the copy method will place the tab at the end (i.e. to the right).
Unfortunately it doesn't seem like AcApLayoutManager.updateLayoutTabs() has been exposed to .NET. However I have found that an Editor.Regen() statement seems to refresh the tabs nicely.
