Tolerances

62 Views, 20 Replies

I see that in R6, in the parameters, there are a couple of new columns
that on the surface appear to be really useful, but I'm at a loss as to
how one might use them.

The one I'm looking at is entitled "Tol.". I would have thought this
might be useful in that one could specify the tolerance of a feature in
the modelling stage and have it carried through to the drawing.
However, I'm completely perplexed as to why it is there and what one
does with it. Online help appears to have been written using the
'Enigma Machine' so it hasn't helped.

Has anybody figured this one out?

Richard,
How about this one. Visual Basic for Application in Inventor. It
certainly is not what the title says. It is very heavily structure object
oriented programming, with no windows to construct, just reams and reams of
terse structured program.
I remember the old days. First portable computer I worked on was a
PDP11, with little round magnetized cores for memory. To turn on you really
had to bootstrap the big box. Flip these switches and then those. and then
stick you program ticker tape in to read in your program. It used basic.
Very little structure, short little words and of course very little that
could be done, but I was good at it.
So much for my fuddle duddle remarks.

When sketching, as you add a dim the box comes up where you type the value,
right click in it and select "Tolerance"

You can add tolerance to sketch dims which pass through to the drawing.

You can also do this when prompted for a value in the Extrude dialogue
etc.etc.

Rory:

Thanks ever so much for your input. By following your instructions I
created a model of a disk Ø5.125 x 0.5 thick and applied a tolerance of
+0.000 and - 0.005 to the diameter. By using the 'Get Model Dimensions'
and modifying the tolerance I managed to achieve my results.

There's no doubt the addition of this feature was well intentioned, but,
for the edification of the IV developers, I'd like to take the liberty
of describing steps I took that me to my frustration:

1/ Copied an existing part and it's drawing. The part is a disk with a
hole in it. Both had to be slightly modified.
2/ Since starting to use IV6.0, I'd noticed the "Tol." field and assumed
I could add a tolerance here. I tried various combinations of right or
left clicking here but the results were futile. Try it. For software
that supposedly works the way I do, this is confusing. If the field is
there, it should do something, or at least it should show that you've
done something.
3/ Spent (wasted) 1/2 hour wading through the on-line help and found
some 'Motherhood and apple pie' type propaganda on the subject but
absolutely no help. Please, do you have to make it so obvious that the
author of your online help has neither a clue about what IV does nor
what users are trying to achieve with the product.

The expectations I had, but was completely disappointed in were:

1/ In the parameters list, click on 'Tol.' and be able to add tolerances.
2/ Once, through the kind advice of someone on this newsgroup, a
tolerance was applied, it should be presented by changing the tolerance
in the drawing.
3/ The slightest, subtlest, hint of a clue in the online help. At least
this could have indicated how absolutely ridiculously restricted this
feature is.


Thanks for letting me vent my frustration.

In the Parameters dialog box you can pick the value in the Equation column.
When the value is selcted the arrow pulldown menu will appear and you can
set the tolerance here as well.

The Tol. column is used to quickley set the dimension at its min, max, and
nominal field.

I agree that it should be easier to find information through the help. It's
there if you know what to look for, but there's no tutorials for it.

They do need to work on the way tolerances are passed to the IDW however.
Right now unless you use "Get Model Dims" which I think only <1% of people
do (I certainly don't) it's several clicks to get them to show up
correctly..

Thank you. I'd love to know how all of you figure these things out.

Do you have any idea what the yellow circle, + and - mean?

It sure seems that way. Why isn't that in help? Is Adesk too
embarrassed to admit this (and I'm not sure I'm referring to on-line
help or tolerance) is just a marketing tool with limited practical use?

And while I'm beating a dead horse, now that I've finally figured out
how to add a tolerance, when I 'Get Model Dimensions' for a dimension
with a tolerance the text appears with an underline. If I manually
apply tolerances to a dimension, which we all agree should happen
automatically, there's no underline. Why the discrepancy? Either it's
an ANSI standard and should apply in each case, or it's not and it
should apply in neither.

Gosh I'm picky tonight.

Richard

I just assumed that the yellow circle meant the dimension is modeled at
nominal; the + models the dimension at its max; the - models the dimension
at its min. I think this may be half useful for checking for tolerance
stack interferences. Although, I haven't tested my theories thoroughly.
