Mass Props Skeleton part

[amedina]

I got a user asking about mass properties in Wf4 M190. Specifically he sets
a skeleton part as suppressed or removed by a simplified rep however the
mass property mass does not change. Its clear to me that the mass of the
skeleton has a value. What is not clear is:

1) Is there a bug that prevents suppression of a squeleton from removing its
mass?
2) maybe the mass of a skeleton part is not counted in an assembly and I was
not aware of this until now? (this would explain why the mass does not
change if the skeleton is removed)

Any directives? tips? I'll try to figure it out today somehow.

Alfonso

There is no mo mass to a skeleton, as there is no solid geometry to have mass.

IIRC, this is intended functionality, as Skeleton parts are not intended to
have solid geometry, only datum planes, sketches, surfaces, axes, etc.

To clarify what others have said, a skeleton part is ignored when doing
mass property calculations. Typically, a skeleton is created with no
solid geometry; however there is nothing to prevent one from creating
solid geometry in a skeleton part. Regardless of solid geometry or not,
Pro/E ignores the mass of a skeleton in mass properties calcs.



This assumes that your skeleton is a true skeleton part and not a
standard part simply assembled first and used as a skeleton.

Great. Yeah I have no idea why the user added a solid to a skeleton. I'll
have to ask him to create a model for that so that he gets the correct mass.

thanks!
