Question

Family table: mass in repeat region

  • September 3, 2015

I have seen other posts and tried them with no success.

Does anyone have a suggestion on how to display on a drawing repeat region the Mass of each individual item on a family table.

Currently I thought &fam.inst.param.name == mass would work.

Aric,

I think that you have to add "MASS" parameter column into family table and enter its values manually. I can't imagine any automatic solution...

In each of our parts and assemblies we have a parameter called mass as a real number

This is in the template so it gets populated at each new model generated.

in each of our parts we have a relation:

/** mass properties of the part file

mass=mp_mass("")

volume=mp_volume("")

surf_area=mp_surf_area("")

cgx=mp_cg_x("","c-x0y0z0","") /* may vary based on part csys name

cgy=mp_cg_y("","c-x0y0z0","") /* may vary based on part csys name

cgz=mp_cg_z("","c-x0y0z0","") /* may vary based on part csys name

/** end of mass properties of part file

in each of our assemblies we have a relation:

/** mass properties of the assembly file

mass=mp_mass("")

volume=mp_volume("")

surf_area=mp_surf_area("")

cgx=mp_cg_x("","asy_csys_def","") /* may vary based on assy csys name

cgy=mp_cg_y("","asy_csys_def","") /* may vary based on assy csys name

cgz=mp_cg_z("","asy_csys_def","") /* may vary based on assy csys name

/** end mass properties of the assembly file

In your bom table, add a column with a report parameter &asm.mbr.mass

based upon your bom table, it will report accordingly.

(qualification statement - at least mine does....)

Family table instances behave differently than standalone parts and assemblies.  Take a look at this article from PTC tech support on how to create a repeat region that correctly updates and displays the mass for family table instances.

Tom,

thanks for sending the link. I have tested CS143060 procedure in CR2 M070 and it works well. Just one additional note: All family table instances must be verified. The verification process puts correct values into weight column.

I wasn't real keen on setting the config option "mass_property_calculate" to "automatic".  This could cause serious performance issues when working on large assemblies.  I think I would turn it on just long enough to have the family table's mass value calculated, then turn it off when done.  The last calculated value will remain in the table, even with the option off.
