Not disagreeing - we use the projected left view as well…
But I’m wondering if this user preference or if this is actually a standard. As far as I can see, ISO 10209:2012 on Technical Product Documentation specifies the first-angle projection but only says:
orthographic representation comprising the arrangement, around the principal view of an object, of some or all of the other five views of that object
Note 1 to entry: With reference to the principal view, the other views are arranged as follows:
— the view from above is placed underneath;
— the view from below is placed above;
— the view from the left is placed on the right; - the view from the right is placed on the left;
— the view from the rear is placed on the left or to the right, as convenient.
In germany we habe the “Hoischen”, a small booklet with 500 pages that is used since the 1940s as a reference for technical drawings, it´s used by nearly everybody in the industry. It says, that left view is the preferred method.
