Hi folks !<BR>> I'd like to better understand the
meaning of "Geometry check" info.<BR>> Anybody
knows where it's possible to get info, docs, examples about it
?<BR>> <BR>>
<BR>> <BR>> Causes are pretty much as Geesaman described; info is
scarce, Help files <BR>> have some info that might be worth considering
(use interactive help on <BR>> 'Info>Geom checks') but you'd spend your
time more wisely cultivating a <BR>> PTC modeling guru. Maybe there's a
course they offer that takes you <BR>> through the error resolution
process. I haven't found it yet.<BR>> <BR>> In my experience, the
chief thing that causes geom checks is accuracy <BR>> issues, especially
between Pro/e and other modeling packages, when <BR>> importing and
exporting models. Model size, for accuracy purposes, often <BR>> does not
translate easily between packages and scale is accounted for <BR>>
differently in each.<BR>> <BR>> Some things that can be done to
aide this data translation, especially <BR>> when we are talking about
assemblies or tooling/manufacturing <BR>> merged/cutout parts:<BR>>
<BR>> 1. Convert part accuracy to absolute (highest
level) accuracy. This<BR>> should be a
realistic proportion/scale/ratio for comparing
part<BR>> accuracies. You can turn this
on by setting<BR>>
enable_absolute_accuracy to YES in config.pro
('Tools>Options')<BR>> 2. In config.pro, set
accuracy_lower_bound to something
obscenely<BR>> small, like
.00000001<BR>> 3. Also set def_abs_accuracy to something
like .00001 which will
come<BR>> up
when you pick Absolute Accuracy in the
'Edit>Setup>Accuracy'<BR>> menu
as the default value.<BR>> 4. Set all parts and assembly
to absolute accuracy<BR>> 5. If you want to "Open" import
files directly, set the
configuration<BR>> option
intf_in_use_template_models to YES. This buys you
your<BR>> default csys, planes,
parameters, settings like material,
units<BR>> and accuracy and anything
else embedded in the start part. If
the<BR>> start part's model units are
different from the import model's,<BR>>
Pro/e does the conversion.<BR>> 6. Otherwise, create a
new part from start part, then do<BR>>
'Insert>Shared Date>From file' and select your .igs or .stp
or<BR>> .sat or etc part type from the
drop down list.<BR>> 7. Regen everything and see if you
get the geom chk again. 95% of the<BR>>
time I have done this, the 'geom chk' went away, Pro/MAGICALLY!<BR>>
<BR>> I've not seen any comprehensive references on this. If they
exist, they <BR>> are available privately. PTC is all about secrecy,
especially in how its <BR>> program works. The more you pay, the more you
find out!!!!! You think if <BR>> you put out for a license, you should know
how the program works!?! No, <BR>> there's much more to pay to get into the
inner circle where they share <BR>> the real knowledge.<BR><BR><BR>Thank
you for reply.<BR>I remember to have seen in the very old ProE manual (maybe
rel 13!) some <BR>pages dedicated to geometry check, but i haven't that
manual.<BR>I generally find geometry check also if there are many rounds and
it <BR>should be useful to have some references in order to avoid these kind
of <BR>problem.<BR>Thank you again<BR>Bye<BR>Pier</BLOCKQUOTE><BR>
<DIV>I remember those manuals, as well. I've heard that they were produced as
PDFs and were distributed with the documentation disks. Never could confirm this
but yeah, you're right, they stopped publishing the bound editions around R20.
Online, under Reference Docs, there is a "Help Topics Collection" that could be
the equivalent of these docs because it seems to cover every module, including
ones on feature creation, part modeling and part design with stuff on rounds and
geom check. 50 Megs of PDF documents ought to be of some use.</DIV>
