…for new documents and every time I launch Rhino?
You could make a script that runs at startup that sets “Left” as active.
Or maybe save a new file as template that has Left maximized.
@Holo is right.
It is not possible to fundamentally change Rhino’s Cartesian, right-handed, Z-up, Top/Front/Right/Perspective default view arrangement.
Set the views as desired.
Save As Template with name you want to use.
Set default template to the saved template: Options > Rhino Options > Files > Template Files > Default
Then, to reset the views, if they are altered in the modeling process, use
-ReadViewportsFromFile“Path to template”
The right-hand cartesian is just fine. The direction of the view is what is wrong. At least in Ship Design. In ship design top view you look down the Z- (same as Rhino), side view you look along Y+ (same as Rhino) but transversal views, which is front in ship design you look along X+ (y+ is to your left, z+ is up) This one is exactly the opposite of Rhino default “Right”.
That is the case in EU at least. I know some countries orient their ships backwards
