Mass properties are not calculated

Just starting on Creo 2.0, and when I save a part (or assembly) I get the following conflict window pop up:

"Mass properties are not calculated"

Now.... I know what it means The trouble is I have not created a mass properties feature or a saved analysis and I currently have no need or desire to calculate the mass properties of my part. I have to check this box off every time I save a file.

Does anyone know how to get rid of this?

It is the mass properties config option:

mass_property_calculate automatic

I have commented it out in my config.pro for the time being. I'm not sure why it now requires a check off every time you save, whereas in earlier releases it didn't. Must be an "improvement".

Something is calling for one of the mass property values, maybe a format is trying to report the weight of the object or even the material callout. Check the relations for the part and the individual features. Something want data. This is not normal behavior for bare bones setups.

There is no parameter calling for any mass property value. I have just created a new part using our standard start part and I get this message even when there is no geometry in the part, just datums.

When I do the same thing, using the exact same start part, in WF5.0 I do not get this message. I only get it in Creo 2.0. Apart from the release of Pro/Creo there is no difference between the two parts, they are both created from the same (WF 5.0) start part.

Check to see if the following config option is enabled

mass_property_calculate

I am also having this problem. After playing with the config settings I can make the error stop showing at the expense of having accurate weight show up in my drawings. To clarify, the setting which stops the "mass properties not calculated" error stops drawing weights from updating at all.

How can I fix the system so that it works appropriately?

Thanks,

I suspect there is an error in the part's mass property parameters and therefore cannot complete the calculation. If you want it to work properly, all the data has to be entered.

If you believe it is correctly entered, you might create a customer service case and have them take a look.

Has there been a significant change in the Mass Prop datasets from WF5 to CREO 2? This error is new and started when we transitioned to CREO 2. It happens with every part, every assembly, and every drawing. Generating a new mass-properties report will stop it until some change is made to the part, like adding a note. Then you cannot save without this error popping up. It has become extremely frustrating.

Thanks,

Thread bump time...

If you don't (want to, or can't) have the option set to Automatic, how do you force an update?

In Wildfire it was something convoluted like Edit -> Setup -> Mass Props -> Generate Report (which we created a mapkey for as it was so awkward), but where's that gone in Creo 2?

Thanks!
