Creo 9.0.7 Assigning density via a material file. Same file is used to assign material to many parts, even several other parts in this assembly. For some reason, with a few of the parts it does not stick. Or more accurately, though the parts dims are english, the density changes to a value like kg/m^3 even though it says lbs/in^3. Not all the parts, just some. I can delete the material, then assign it again, and it sticks for a while, but after big changes or when opening them next day, it reverts to the wrong density. This is not new to me, and it is not unique to the one material file. On this project I finally got so frustrated I documented it carefully via video and sent it to tech support. It's been a week, and so far only a call to say they are looking into it.
Because weight is of particular interest in this assembly, this problem is especially annoying. However, I have seen this a few times in the past year or so in Creo 9. For a lot of work, accurate weight is not a concern, so I chose to NOT waste my time reporting it. That's how most of the many bugs are. I have opened so many calls with PTC that are bugs, then after a lot of extra time to document it, they whitewash it or tell me they are not a priority for development.
I posted the call number so those internal to PTC can look and see, and so others reading this post know there is more to it than just complaining.
I've been working in PTC products since 1994, v.13. The bugs seem to be in waves where the software is almost unusable for a while, then they start to get a handle on things again. Never is the software bug-free, but sometimes less than others. Right now is bad, so I don't know what's up internally, but someone needs to pull a clue and start paying attention to the quality (if I can use that word loosely) of the product.
