First off, I apologize if this is the wrong forum....
There is a big dilemma where I work right now. We have process units
which were done in Pro-E that we have sent out to bid. Some models used
within the Pro-E models do not have a Pro-E drawing associated with the
model but simply have an old hand drawing. Apparently we are getting
some feedback from some vendors that they want models. I assume they are
talking about STEP files for example to compliment the drawings they
will be receiving in hardcopy format. Now the models were created to
nominal with the tolerancing referenced on the drawing with a note :
Machining tolerance per js-Js13 (ASME B4.2)
It seems to me that as long as the vendor has the drawing with the
required dimensioning and the tolerancing noted either through the note
above or actual tolerancing within the dimension, that the STEP file
could be used by them to input into their CNC for example with the
understanding that all tolerances are included on the drawing and not
necessarily in the model.
There are people here jumping up and down thinking that we may need to
create Pro-E drawings for all of the parts that only have a hand-drawing
(of course the deadline for finishing the project is looming). I just
don't think we will need to do that. I am wondering if anyone with a
better machining background can help me understand the vendor
perspective. I have been asked to be included in a big meeting tomorrow
to discuss these issues. It seems to me the vendor wants the STEP file
to import to make their job much easier and less time consuming.
How these issues were never thought about from day one boggles my mind,
but apparently they never were.
Also, as an aside, are there any add-on software packages that you know
of that could automate the process of creating step files for models? I
really would like to avoid pulling up each part and saving as a STEP
file for example.
Any responses to this blanket inquiry would be much appreciated.
Thanks,
Nick
