Inventor NG World Cup - quick poll

[Anonymous]

Hi all present and future participants in the IvNGWC challenge.

I've been given the suggestion that the PDF challenge file should be
accompanied with a SAT model file and even a 2D DWG file to avoid
misunderstandings/misinterpretations regarding the 2D layout (you'll then be
able to zoom in, control the LWT etc.).

What do you think?

1: Do you want a SAT file?

2: Do you want a 2D DWG file?

3: Do you want both?

4: Don't you want any changes (PDF file only)?

Hi Peer

Since I was the one bringing that suggestion up to you yesterday. I will offcourse answer here.

My suggestion is that we get dwg + sat models instead, by that the contest is about pure 3D
modelling and thereby not inflicted by 2D "drawingreading" abilities by individuals.

PDF files with lineweights = on isn't for a instance not so good for zooming.

For my sake many real world modelling challenges was modelling from a physical model, like the
shoesole ( http://www.techsolution.dk/saal.gif )

With one of the former contests, I had to use around 1 hour, calculating the needed dimensions
and interpret the drawing (not my strong point :-), then I started Inventor and 15 minutes
later the model was done.

So in other words "Inventor" NG Worldcup is in my opinion primarely a drawing-reading +
modelling contest.

I can see from the other respondees in this thread that I'm pretty alone with my standpoint and
I guess that future challenges still would be based on pdf-files and I will offcourse make the
models, but it isn't sure that I will send my results and time.

Bottomline I thing that our Inventor NG World Cup is a great idea 🙂

Hi Peer,
keep it as it is. You are doing a splendid job. It is great fun and we learn
a lot.
I must admit that I hate it when the model is dimensioned in Imperial :-). I
wish the other side would go metric 🙂
Keep up the godd work and keep Inventoring

God week end

Metric? What is that? Isn't that a base 10 system?

Sounds complicated to me.

I am probably going to mess this up but............
2 farthings to a half penny.
2 half pennies to a penny / copper.
3 pennies to a three pence / thrupenny bit (12 sided I think).
6 pennies to a six pence / tanner.
12 pennies to a shilling / bob.
2 shillings to a two shillings / florin.
2 1/2 shillings to half a crown.
5 shillings to a crown.
10 shillings to a ten shilling note / ten bob note.
20 shillings to a pound.
21 shillings to a guinea.
Penny - pennies & pence, as in one penny two pennies & three pence bit.
Old penny 1d, new penny 1p?
We gave up imperial and now by law you cannot sell by imperial alone!
Now its just P's and pounds.
So why do you operate a imperial measure and a decimal currency?
Foot and inches............oh don't start that again..........:)

We have an interesting thing going on here in Canada. As a country we are
"Officially" Metric, but being so close to the US and having so much trade
with the US, every industry I have worked in since I started working uses
nothing but Imperial.

Lars,
I don't fully understand your request.
You state that one challenge took you 1 hour of calculating and
interpreting - while the modeling only took 15 minutes.
How are you planning on creating the model from a dwg+sat file? By bringing
in geometry and extruding from there?
Or open the SAT and create a bunch of sketches from the existing geometry -
then deleting the dumb model and extruding/revolve the remaining sketches?

What challenge is there in that?

We should all be experienced designers and engineers - we should all be
capable of reading and interpreting 2D drawings - it's supposed to be part
of our foundation of knowledge.

Where am I wrong?

I try and do everything metric, which is tough when it comes to things like trilobe thread forming screws with flat undercut heads like we use EVERYWHERE....... but it can be done. Seems like a lot of the arguments to not go metric disappeared with digital CNC equipment. It no longer comes down to cranking the handles on the manual "etch 'a sketch" mill.

Problem is there is so many "imperial" parts, nuts, bolts screws etc.. out
there that you could never do away with them entirely. Therefore people
will continue to use them. I have no problem with the metric system (in
many cases I prefer it) but I don't think we'll ever convert over.

It would be a similar task to switching us to driving on the left...

It was sucessfully done in Australia around 35 or 40 years ago (1966 I think). Change to Decimal Currency from pennies, shillings etc. I think the change to mm from in occurred at the same time.

PS. Being too young to have lived in anything other than an age where mm are used, it was a shock to the system to go and work for an Aerospace company and have to use 3/16" and 5/32" etc all of a sudden (bloody yanks! 🙂 while on work experience (sorry "Industry Based Learning") at uni.

[Anonymous]

It's absolutely sad Steve but I know machine shops who will still sit down
with a calculator and convert each and every dimension over to Inches if I
send it to them in metric. I always make a point of showing them that
little "mm" button on their digital readout displays on their mills. They
just shrug it off.

My main problem with going 100% metric is when I know the parts will be made
in the U.S. first - then subsequent parts made off-shore. The U.S. just
doesn't have readily available stock in metric sizes. 1/4", 3/8", 1/2"
plate must be called out. I don't know what they do when they make the
parts in Asia.

Over here we seem to have both sizes readily available, but it is likely that one or the other is substituted. ie for a 2x4 lump of wood (still referred to as that in some places) you would be supplied a 50x100. I think the commonly available sheet sizes are metric conversions (1.6mm approx 1/16in) etc, same with plate sizes (6mm ~ 1/4). I am happy to say though, it doesn't really effect me though in what I do, only when we have to deal with American datapacks (I just can't imagine what 5/32 is).

Looking at history, I don't think migrating to a reasonable system of measurement
is that big of a stretch.  I use to work on English cars which had Witworth
hardware.  Back then, you could pick the stuff locally, now it is considered
NOS or special order.  All it would take is about 50 years of producing everything
metric.  About 25 years into it, getting inch stuff would be like getting
parts for a '50s Corvette (you can get them but it takes a little more effort).
 The conversion was well on its way in the early 80's then stopped by our
president.



Seems to me that a couple more space mission failures due to Imperial measurement
screw ups and...  Had it not been for the short sightedness of our then president,
the US would have been well on its way to conversion to the metric system.
 Heck, back in '72, my mother converted and loved it (she didn't like working
with fractions).

No, the sat-file is only for viewing and eventually measuring, the same is true for the 2D dwg-
file.

The idea is offcourse to build the model from ground. My idea is that our Inventor cup should
be a true modelling contest, not drawing reading/ interpreting contest as it primarely is now.

That sound as a very clumsy method 🙂

Some of the challenges during time is based on 2D-drawings that for one example among others
doesn't contain primare outer/ main-dimensions, which is wrong according to DIN/ISO standards.
Sorry but you asked, so I had to bring it up.
So in other words the 2D documentation in some of the challenges can be better, despite the
fact that it is possible to retrieve the nessesary information based on the drawings as they
are. But this is done without Inventor, but with a calculator instead 🙂
