How Change Default Zoom Level When Opening New Document

If "Zoom to Height" is satisfactory to you, then you might use CorelDRAW's regular workspace customization to assign a keyboard shortcut to that Command. That would get you down to only having to use a single keystroke to get the zoom you want.

As an alternative, you could look at my Zoom to Selection Plus macro. That includes a sub that allows one to "zoom to page", but with a user-defined amount of "padding".

That could give you a "zoom to page" that doesn't waste any of the available space in the drawing area in CorelDRAW. As with any CorelDRAW Command, that sub could have a keyboard shortcut assigned to it to make it a one-click tool.

Hello,
If You use VBA automatization You may ad this code in Globalmacros.gms at ThisMacroStorage Level, DocumentNew event
Private Sub GlobalMacroStorage_DocumentNew(ByVal Doc As Document, ByVal FromTemplate As Boolean, ByVal Template As String, ByVal IncludeGraphics As Boolean)
ActiveDocument.ActiveWindow.ActiveView.ToFitPageHeight
End Sub

After this New documents will be opened always at Zoom to Page Height level and more then - no any hot key must be pressed.

Greetings!
