Unable to Project Work Planes

Can anyone help me? I can't project any workplanes onto any of my sketchs. I am using Inventor 6 SP2.

Sounds like a similar thing to what I am experiencing. *0% of the time a rebuild all will show an error on these parts. It just seems that whatever is causing the error is buidling with each successive derivative to the point that it falls over completely. I'm getting an error on one part witha rebuild all that says "Projection Failed". This is not attached to any sketch or feature that I can see. I'll post an image to iCF.

steve,
I've got a hard time tracking this stuff down, even with everything
right in front of me and full control of the model. Looking at
your file list though, and the fact that you have a whacked workplane
associated with a derived surface, I'd wonder about "file2".
Is it associated with your whacked WPLane? Unless some of the names
are out of order, it looks like it's used early and later on in your
structure. I guess you just go to the bottom and work up, until you nail
the problem.
good luck,
darvin

browser window), i think that this may be the problem child file.

Its hard to imagine what's going on here as the files not in front of us,
but before reading this post this morning and having read your last one
above it dawned on me that all is not right with the file.
I do not remember all the details or even if Kent made them public to this
NG at the time so I cant compare the two situations, but if your file is not
referencing any other file then it should survive a rebuild all. I cant
remember who said it but using rebuild in a file after every new feature ( I
normally do it after 3/4) shows up corrupted sketches etc. After two or more
years of using IV I am now spending more time rearranging sketches and
features in files so they are better at surviving changes further up the
browser Like I said I am not making a comparison with Kent's situation.
Like Darvinv's said you will have to start at the bottom of your tree of
parts and redefine sketches / workplanes as you go and fix the errors as
they appear...... as they will.
Final tip after work on your file which say is just a plain old IPT save
then rebuild all and save again before close confirms the files ultimate
integrity, safe for another day and any errors will appear then not
tomorrow.
I would have thought that even a file that contains other derived files etc
would survive rebuild all?
Maybe someone can comment? All this especially if the file(s) contain a lot
of work, good luck and I am sure that I am not the only one who would like
to get my hands on your file....looks great, we understand your
confidentiality agreement not allowing you to post, cheers.

I have an update from information supplied by Quinn. He has found that the derived component origins have become misaligned to the origin within the part file I am working on. All methods of measuring show everything to be OK as far as alignment goes, but the kernel or soemthing internal is not seeing it that way. If Quinn recreates the workplanes relative to the derived compenent and not to the origin, the work planes project OK. Autodesk have asked to see the files and I'm hoping that I can give them to them to have a look.

Steve
