The documentation of CAD software seems to be getting worse and worse. Two reasons for this, I think. One is that CAD software is becoming more and more complex, as well as increasingly interconnected, and that outpaces the ability to clearly document its functions.
Another reason is that CAD vendors rather that you pay to learn their software, preferably paying them. None of this on-your-own-time nonsense. We have highly-paid professionals standing by. Kind of like being bullied into buying an unwanted extended warranty: you've paid for the product; now pay us some more. Oh, and don't put away that chequebook just yet...
Or maybe, just maybe, CAD vendors haven't gotten around to fixing it, after exhausting their resources on programming and marketing. As in this example: I'm perusing the online docs for IntelliCAD v6.4 (the very latest version) and come across this documentation mired in antiquity:
PLATFORM -- Indicates on which platform IntelliCAD is running.
Saved: Not saved
Range: Microsoft Windows 98 or Windows NT
Glory be! The old days always were the best.
