Parameters

[Robert_26]

Dear All,


I want to show the weight of assembly model. I have assembly and sub assemblies, I need to show teh weight of this sub-assemblies, I f anybody knows the coments of the parameter I am using &PRO_MP_MASS but this funcion is calculation entire assembly model, Please Help me

define a parameter in part / sub-assly' / main assly' as shown below.


WEIGHT= mp_mass("")


regen the model. define the parameter in your drawing format &WEIGHT and you will get it.

How do you add the parameter in drw part/sub-assy/main assy template files? I've tried but can't since there is no mass. Or did I just answer my own question?


Also, when I add the parameter "weight=mp_mass("") to a prt file with a model in it, it still says "Mass properties for this model are not calculated yet." What am I missing?


I'm using basic wf3 package.</BLOCKQUOTE>

You can use pro_mp_mass in the parts but not the assembly (I think)..


What you can do is run a Mass Properties of the assembly and save an analysis feature which can get the weight of the assembly. You'll want to make sure density or material files are assigned to all the components first. Make sure the analysis feature is the last feature in your parts/assemblies. You can use it in all your parts, family table part and assembly files. For the family table part, you'll want to add it to the generic. (pro_mp_mass will still work for regular parts). In the analysis feature, you can access a parameter, which you can rename to "WEIGHT" and then you can access that on your drawing. If you have WF4, you can put the analysis feature in the "footer" (I can't remember whether this functionality is out in WF3 or not.)


As an aside, if you could put the mass props analysis feature in the footer, perhaps it makes sense to add this feature to your template asm and prt. Something to try for the future perhaps. (We're still on WF2 and transitioning to WF4.)


Good luck,


JD

kdjolly,


first u need to setup density for calculating the mass. here is the way....


#EDIT #SETUP #MASS PROPS....


there appears the window and set your density and be careful about ur units. this value should align with ur set units.





these things u can set in ur templates so that u can avoid repeated entries. since 4 years i am doin this n getting pretty accurate results. even i m using WF3.


hope this helps u.

Mass parameter for the calculating individual part weight in assembly is &MASS:0[.2]
0 is Session Id
[.2] is No. of decimals
You can find Session Id of each part by going to Relations--> Show--> Session Id

Please add


mass=mp_mass("") at the individual parts under Relations before typing in


&MASS:0[.2] .You can also test this in your assembly Relations -->Evaluate for verifying if the mass calculated is correct
