@Jeffin90620 yes, north is at the top of the screen. But, since I am trying to stick with landscape for simplicity, I would actually prefer north to the right. I can select the viewport and that gives me a rotation handle, but rotating it does not change the view inside.
@JohnR Workspace / Model Space Floating is grey unless the viewport is selected. If I select the viewport, I can select that Workspace option, but I am unclear how it is that I would change the view. Select everything and rotate?
The remark about Camera Movements got me hopeful since another task I need to tackle is adjusting the isometric views so that the point of view is closer in, so that the walls don't block so much of the view. However, Camera Movements is greyed out in Paper Space. I have done this kind of adjusting the point of view, but it was many years ago and was done in Model Space as I had not yet discovered the joys of Paper Space.
