How can I create a 45-degree rotated top view in my drawing?

I’m currently working on a design for a large techno show. The layout, viewed from above, consists of trusses and squares that are rotated 45 degrees. I would like to create a top view of the design where the trusses appear as straight lines (i.e., rotated 45 degrees), so they are shown properly in the drawing. This would be especially helpful to fit multiple trusses on a single page. Does anyone know how to achieve this effect?

I am familiar with the YouTube video “Capture Focus Swing Camera,” but unfortunately, this approach doesn’t seem to work for the final plots.
