Inventor 11 save error.....

[Hickoz_bro]

Hey guys,

got a Drawing i'm working on at work, but i can't save it... when i try "save" i get "access violation - no RTTI data" error... or something to that effect, can't remember exact wording...

how do i fix it with out closing inventor and loosing my work?? i can't "save copy as" either, unless i use a different file type... what file type can i use that will retain all the formatting, imported objects (.jpg) etc..

FYI, i'm using Inventor 11, SP3...

any help would be greatly appreciated, i'd like to save before inventor crashes for some reason, and i loose the lot anyway...

I think I would not trust the file anyhow. I would Ctrl Alt Del and go back and open the file as I saved it 10 minutes ago. You do save every ten minutes or so, right?
You might have an Oldversions to recover.


Oops, now I remember - you were the one wanting autosave

you may also know me from such threads as "Anyone else find Inventor the most frustrating program ever?" and "Basic general questions?"


no, i don't save every 10 mins or so... the idw's don't take more then maybe 30mins to do, start to finish. the problem is save, so if i can't save, how would it have saved previously???

btw? when have you ever been able to "TRUST" an inventor file?? we get errosr happening for no good reason all the time... just today, i had a sheet metal part that i couldn't constrain to... i had to go back and re-define all features because it "forgot" what i had done, simply didn't recognise the contour flange feature from start. and btw.. what does "general error" mean? 'cause we get that alot too... and what about "your trying to constrain to geometry which no longer exists" when your clicking "apply" on the very constraint it's refering to? and what does 2009 inventor do that's so special it can't run on non SSE2 processors?

WHY, if inventor is the designers choice, does it have SOOOO many flaws??

and why is it that the apparent answer to all of the above questions is "do some proper training" when anyone i speak to who IS in the know, and has been using inventor since the beginning says that it really does just have all these problems... people talk more about inventors flaws then it's brilliant features...

some more research of this error shows it to be just one of those things...

no apparent cause, no apparent cure...

Re: Access violation - no RTTI data!
Pete,

This is a bit of a generic error and it tends to be minor (ie not a
crasher) - no run time type information (or some variation), this has always
been one of Inventor's error messages (since R1).

Each situation of this error is most likely an unrelated case; each one
needs to be looked at.

Usually there should be no need to restart Inventor or reboot the machine.
However, if it starts showing up all over the place once you've seen it
once, a restart of Inventor is a good idea.

With that said, if you can replicate this error with a particular file
(would be kind of surprising since it is a run time issue) or have a set of
reproducible steps we would be interested in looking into it further.



Sorry I don't have more to offer,

i'll just delete stuff until it saves... or crashes... which ever comes first.

I think the people you are talking to don't know what they are talking about. You can take that statement for whatever you think it is worth, but on my reputation I state that you should not be experiencing the problems you are describing. I guarantee that if I was at you site I could eliminate these problems. Period.

I got the RTTI error yesterday. You have to restart Inventor. :(
And I "habitually save" about every 2 minutes out of habit.

We have lots of problems also. The lady next to me was trying to hatch an area in a drawing, and it took most of it, but for some reason it would not take rest of the identical ribs. So she had to redraw over the tops of the already projected lines and then it worked.

Just yesterday, I mirrored two sketched squares, to the other side of the sketch, then click "extrude". Inventor only recognized the very first original square (in the upper left). I emailed Inventor and they said ,"I’m also guessing that you mirrored the sketch and only the original sketch is extruding. This is because the coincident constrain can’t be mirrored to reference geometry." But I can reproduce it now and it works so I don't know what the problem is/was.

Lately when I "project geometry" I have to redraw over the tops over the edges of the projected geometry, because for some reason Inventor sometimes does not see the entire projection. Plus, you cannot "trim" projected geometry. Solidworks lets you "trim" converted entities (Projected geometry), which is nice. I find myself having to wait for the "select other" box so I don't pick the longer, projected line I am using for reference geometry.

JD - Becareful about offering to fix all my problems, you may just find your inbox full of screen shots like the one below... can you explain why my "heap" isn't big enough?? IMO inventor is a big enough heap as it is...

Arusho - According to autodesk (unofficially) you shouldn't need to restart inventor for the error to resolve it's self, however in both cases of getting it myself, you have to resolve.

when you tried to hatch, i presume your refering to the "fill" tool (unless there's something i don't know about, which given my total lack of education is more then likely) you can only select one region at a time (a brilliant feature of inventor... they really thought this one through) so in order to hatch several regions you need to repeat the process several times... (that's the kind of inventor efficiency we all love)

however assuming you know this already, then perhaps the projected geometry is being displayed as "sketch only" or something like that.

as for mirroring sketches etc, this is another brilliant feature... unless you draw a rectangle or a closed region shape (circle, rectangle etc) or trace the profile with the line tool in a continuous loop (don't trim, extend, or join) then you can't mirror, or pattern your sketch, then create a feature from that mirrored/patterned sketch. to demonstrate, draw 4 lines no joined, then join the ends to make a polygon using the coincident constraint tool, then create a pattern and try to extrude the pattern. that shouldn't work... however if you create a polygon using the rectangle tool, then you can pattern/mirror it with no problems and the pattern will extrude no problems...



Now... to see how my first error ("access violation - no RTTI data") ended up... see below

As if inventor isn't a big enough heap already!! it wants MORE!

Based on my experience with others having similar problems these type of problems are most efficiently solved by being on site rather than trying to solve by phone, email or forums.

can you even so much as offer a suggestion as to what i might BEGIN to look for? Autodesk themselves don't even know what causes the problems i've been having? so where do YOU start?
in MY experience any technician who comes to site does exactly the same thing the useless new guy does... i.e. blindly looks through the options and settings looking for anything awry, and if they don't find anything then they just make up some elaborate bull**** hypotheses about why i recieved the error, and why they can't fix it, then charge you $120/hr for their troubles...

[arusho]

holy cow! Never seen "heap" before.

Did you turn down everything? I.e. The Performance settings. Is that all turned down? Whats your video card, etc.. (or did we cover this before?).

Oh yah, I meant "FILL" which is "hatch" which looks like a paint bucket. :?

Also, contact your local reseller, I think you guys are paying a "support contract"? Yesterday I told our reseller that they were not doing a very good job and we want more training and knowledge, etc...I told him I told my boss "we are looking at Solidworks because Inventor support is really bad"...So they said "we will come out next week!"
Or just look at Solidworks, which I really love. :D
Good luck!

arusho - i googled the "heap" error and all i found was 3 results... so obviously it's not that common, i've been e-mailing back and forth with autodesk to try and find a cause for the problem, but no solution as of yet.

Hadn't thought to contact the reseller to be honest, i haven't dealt with them myself before, so it didn't cross my mind, but i might shoot them an e-mail to see if their support is worth anything... and yeah, i think pulling the solidworks card is a good choice... we've got both inventor 2009 and solidworks 2008 here at home and to compare, Solidworks is Beethoven.... Inventor is Karaoke... it's got SOME nice features, but it's not enough to win me over..


EDIT: Oh, back to that heap error... we haven't touched any performance settings at all, the computer has been running the same setup for weeks with only the usual random crashes, but nothing this bizzare... i can't help but get the feeling it's related to page file size... which is 1.5Gb or something like that?? i got the "HEAP" error after "undoing" several times to see if i could find a point where i could save... that's where the RTTI error turned into the HEAP error...

[arusho]

Call your reseller! I assume your company is paying an annual fee for support (probably thousands of dollars!)? And I assume you never talk to them and they never talk to you? (unless you upgrade, but that is only network support, not user support).

After I told my reseller last week, "we might buy Solidworks" they are coming out this week! I said "we are paying you guys a lot of money, you need to be out here once a month - just take a walk around for 30 minutes and see if we have any issues, and also we need someone to talk to", (lately the say, "we don't know, we will call you back" then they call back and say "uuuh, just upgrade to SP2, maybe that will fix it").
