Actually, for top view it is 0,0,1, so it seems the vector is already reversed.

But then as I said, why am I able to enter any value, and that includes values greater than 1? (try it you'll see) That is why these values confuse me. Or maybe they're coordinates for a start point of a vector ending at the center of the object? And why sometimes the view rotates, like the ISO that you need to rotate 60º to put it right? I guess I'd need to familiarize myself with Coin3D to find out. Which considering my level of understanding, I'm probably better off experimenting blindly till I stumble on the right numbers by accident.

When I model in Solid Edge I like to toggle between iso, dimetric and trimetric views, I have keyboard shortcuts mapped. I'd like to get the same in FreeCAD's Gui, but it is a very minor and unimportant wish. For drawing views I find that either dimetric or trimetric are often clearer than iso.
I found the Automatic Drawing script in the Macros Recipes page and I'm trying to modify it to my needs. For one thing I'm used to third-angle projection, first-angle projection confuses the hell out of me! Those silly north americans!
Changing the ortho views direction and rotation was easy but now the views are not aligned anymore. Ah well, another thing to figure out.
If I ever manage to develop the knowledge and skill, this is what I'd like to do: a drawing view wizard. First you choose your base view (top, front, right), then you're given a dialog box where you tick the projected views that you want (this capture is taken from Solid Edge):
