Mass property calculation could not match requested accuracy

I've has Inventor tell me this for thin walled tubes with holes in them, but
not for a simple part like the attached one. Autodesk are you listening
yet? This has been an issue for a long time. Mass calculations for parts
with holes on curves do not work properly. On many parts the error comes up
with "low" selected. By default each time I try to save the file, the error
window pops up.

Sometimes it occurs with "Very High" as well.

Im getting this error too...its a pain in the **** ...every time I save my assembly this error box pops up a heap of times (one for every part in the assy that has a hole on a pipe at an angle to the pipe centreline (Im modeling pipe launders in a process plant so theres lots of em)....Is there still no fix for this?????

The ID that River mentioned has been resolved and solves this issue with the release of Inventor 2011 which includes the new Autodesk Shape Manager (ASM). Thank you.

I still see this issue in INV 2012.

I dont think this has been solved. Has it?

Autodesk - What is going on here??!

 

I am also running Inventor 2012. Professional 64 Bit SP2 and I am having the same problem. Why is it mentioned that the problem has been solved in a previous version of Inventor only to find it returning in a new release?

 

Come on....

There could be circumstances where the shape of the part is too complex for the ASM kernel to calculate mass properties with very high precision. Especially check if you have any complex surfaces or surfaces of bad quality in your part (for instance due to import from other CAD systems).

To find out if we are talking about a defect or not we need a copy of your files. Thanks.
