They have models of different arms and hands so that this can be checked. The programs are somewhat expensive, but nothing compared to the cost redesigning everything when something doesn't fit. It probably cost us a quarter million dollars just because an extra large cup in the cup holder would be hit by the overweight operator when (snip a dozen other specific things putting everything at the right limits...) and there we could fix it by making the cup holder smaller, but we still had to pay the engineers to rerun the program after the redesign just to make sure that the new cup holder wouldn't affect something else unexpected. <br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Is it worth it?

I've got a dual monitor setup, 27" in front of me and 21" just to the right. When doing CAD work, it's mostly done on the main screen, with the smaller one containing notes, word processor, internet
browser, calculator, useful tools along those lines. But to comment on scale: A practical problem I run into is with small parts. It is a basic functionality of CAD to zoom, pan, and rotate the part or assembly on screen. You can take a tiny part and fill
the screen with it and lose appreciation for scale very quickly. <br></div><div><br></div><div>SO<br></div><div><br></div></div><div style="font-family:Arial;"><br></div><div class="qt-gmail_quote"><div class="qt-gmail_attr" dir="ltr">On Wed, Jan 15, 2020 at 12:32 PM James Peck <<a href="mailto:jamesgpeck@hotmail.com">jamesgpeck@hotmail.com</a>> wrote:<br></div><blockquote style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204, 204, 204);padding-left:1ex;" class="qt-gmail_quote"><div style="font-family:Arial;">When vehicles were designed on the board, they drew in 1/2 scale. You could look at a drawing and relate it to reality. If you taped a drawing to a wall, you could get a sense of the vehicle size. If a designer had a full size or 1/2 size CAD screen, those
inaccessible places would be much more noticeable. People doing 3D solid modelling sometimes have multiple screens, one for each view. It would be difficult to design anything on a smart phone screen. It is not much easier on a small monitor. Monitors do continually
get larger, just like TV screens.<br></div><div style="font-family:Arial;"> <br></div><div style="font-family:Arial;"> Some years ago I read some issues of a then DaimlerChrysler employee newsletter. One article covered a group that real world verified that all maintenance operations could be performed on a new model. If the maintenance could not be performed, the group would
have to design a specialized tool or get a tool manufacturer to design the tool and offer it for sale.<br></div><div style="font-family:Arial;"> <br></div><div style="font-family:Arial;"> They did all this after the vehicle had been designed and production was imminent. I am guessing that moving heaven and earth would be easier than getting the product design changed.<br></div><div style="font-family:Arial;"> <br></div><div style="font-family:Arial;"> Toyota which emphasizes production efficiency not product design may not do it any differently.<br></div><div style="font-family:Arial;"> <br></div><div style="font-family:Arial;"> Cecil Bearden AT List member, Oklahoma farmer, and Professional Engineer (<a href="mailto:crbearden@copper.net">crbearden@copper.net</a>); <snap> This is the problem of designing with AutoCAD and those other computer drafting programs.

has no idea of the clearance in the finished product. <snip><br></div><div style="font-family:Arial;"> _______________________________________________<br></div><div style="font-family:Arial;"> AT mailing list<br></div><div style="font-family:Arial;"> <a href="mailto:AT@lists.antique-tractor.com">AT@lists.antique-tractor.com</a><br></div><div style="font-family:Arial;"> <a rel="noreferrer" href="http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com">http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com</a><br></div></blockquote></div><div style="font-family:Arial;"><span>_______________________________________________</span><br></div><div style="font-family:Arial;"> <span>AT mailing list</span><br></div><div style="font-family:Arial;"> <span>AT@lists.antique-tractor.com</span><br></div><div style="font-family:Arial;"> <span>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com</span><br></div></div></blockquote></div><div>_______________________________________________<br></div><div>AT mailing list<br></div><div>AT@lists.antique-tractor.com<br></div><div>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com<br></div><div><br></div></blockquote></body></html>
