Yes, the “User Guide” as it is is horrible. Whomever wrote it likes to make up terms, the bane of Windows. For example, what is a “Windows Menu”? They are of course referring to the Windows, drop down menu, with items listed on it. They tell you to go there to find Windows Dialogue boxes, or something else they refer to as a Windows Dialogue box tray.
A dialogue box could be anything. This ‘tray’ item is a mystery, but typical of Windows making up words or phrases no one has heard before. And nothing is cross referenced so information just ends, hanging in space. What now?
The computer industry needs a formal vernacular, what exists now is just the similar ramblings of various electrical engineers and the like, who use common phrases get used enough that the rest of us pick them up, but there is no formal Information Technology dictionary, as there is for medicine, engineering, etc…
So people writing guides come close to uniformity, but seem to always ‘make stuff up’ at the critical moment of information delivery. Why is Layout so confusing? Because no one defines concisely what it does. You try to learn routines that don’t have any apparent use. Just what exactly is a layout document for? To pull permits? Then Layout should have a routine for developing those presentation sheets.
To present concepts to a client? That would be another routine, less focused on specific items as much as focused on effective presentation format, the big picture.
