Hi there
I have a critique based on experience with electronics circuit board design using library database on components. Often its wrong and the components cannot be solderd onto their pads because of inaccurate dimensional data. (when I designed circuit cards I made the CAD/components guys check every outline) Most library driven systems depend upon rebuilding components, in the database, which is a waste of time for an individual. Multiple entries for each item are not allowed, yet my tent may weigh 5 ounces more than someone elses because - its seam sealed, or dirty, or has an extra flap sewed to it. Its the ponderous side of computer usage.
