mass prop symbols in relations

[procadman]

I've done this for every release since R13 but I'm having
an issue with WF4:

using the relation weight=mp_mass(""), so I can get an
accessable model parameter for dwg display etc, returns a
"
warning Model changed since mass props calculated. May
need to recalculate." error.

This error remains no matter how many time I run Mass
Props.
Furthermore the value for "weight" remains 0.

I've loaded a material file with the correct density and
it shows up correctly in the Mass Props info window.

What am I missing?

the new parameter is PRO_MP_MASS, rather than MP_MASS

 

[procadman]

Thanks. I'll try that.

I still use mp_mass(""). I get that error message also, but it goes away after I regenerate. Is there a config/pro option that covers this?


pro_mp_mass doesn't work for me. Error mesage comes up:



Invalid symbol 'pro_mp_mass' found.

 

[procadman]

I spoke too soon.
The error I now get is:
"Invalid symbol 'pro_mp_mass' found."

using the relation weight=pro_mp_mass("")

 

[procadman]

Sorry,

Didn't see your follow-up post.
I'm not sure of a config option for it.
I will look further.

Don't include("")in the relation when using PRO_MP_MASS. There may have been a time when you needed to create a relation to get an accessable mass parameter but you don't now.

That works.

thanks,

pro_mp_mass without ("") eliminates the constant "recalc"
error.

However, using the relation "weight=pro_mp_mass" still
returns a value of 0.000 when evaluated.

Analysis/measure/mass prop displays the correct result.

I think the mass properties need to be run. Try running the mass properties with Edit>Setup>Mass Props and select Generate Report. I've noticed in the past that selecting Analysis>Model>Mass Properties doesn't seem to update the PRO_MP_MASS value. The other thing you can try is set the option mass_property_calculate to automatic.
