Just got this error again. Adding a hole feature to a piece of angle steel from content center...

Anyone know what RTTI data is?

Please continue to help Johnson narrow down your issue but to answer your question:

RTTI is Run Tim Type Information

It is a programming construct used in many programs to determine the type of a class/object at run time rather than compile time.

I almost always see this error when we try to "cast" a NULL pointer to the type of object we think it is.

It is a software coding mistake or bad assumption on our part. If you can get a reproducible case to Johnson we can fix it.

I've never seen an RTTI error that we were unable to fix.

Hi Johnson,

I just sent you an email, and included the file I was working on when I got the RTTI error.

Thanks for your help!

And yes, I always submit the crash report when I get one in IV.

I don't always answer the canned email I get afterward, saying "I'm a developer, please send me your files".

I have never received a response back from those and figured it was a waste of time.

Thanks

Ben

Ben,

 As one of the developers 🙂 some crashes are data specific so sending us your files if you are so inclined is VERY helpful.

Fixing a crash/issue from a CER is often very difficult.

If you can give us the file(s) and say, do this, then this, crash... we can fix those!

You may not receive a response after you send the files but we absolutely use them and appreciate them

Ok, I'll definitely keep sending them then.

I won't even pretend to know the nuances of creating stable software; I'm sure it's super difficult.

I'll help in whatever way I can.

Hi,

I can only second Steve's comment. Thanks for any help to reproduce a crash/bug with a set of reproducible steps.

I have a way to reproduce this "Access violation - no RTTI data!" error.

Our company has decided to use Enovia based PLM and through the Inventor integration when logged into 3DExperience, if you go to a file through Windows Explorer that you have not had open before signing into Enovia, then go back to Inventor, you can not do anything because everything is froze. It is not crashed and you can not see the error message hiding behind the Inventor window.

If you do a Ctrl-Alt-Del and bring up the Windows Task Manager, highlight the Autodesk Inventor and right click  you will get a pop up window and go down to Minimize, select that and you can now minimize Inventor to task bar, then you will find the error message that you can exit out of and continue working.

This happens every time with this senario as we speak, which is a pain, but doable for now.
