Prostructure members to use the density "mass" that is in the material database.

The issue is that the only place the member gets the density is from the that part and family "Report Components Tab". so not able to have different materials EG stainless steel member that have the same part.
there is a material garde in the data group but is only a label not anything to do with the type of material.
This is the same for Plate if you want the mass of grating and FRP grating you need to have a different part for each item that need a different mass.

How frequently will feature be used? Several times a day
How much time will you save? Having the correct mass for items would be a good idea

    Hi Johannes

    There are a number of things that happening here.

    1. The material mass is been calculated from the Family/Part Editor Reports tab (see image Mass_1)

    2. This is then only a static formula that is using the density in the components section of the Family/Part Editor (see image Mass_2)

    3. The material grade in only a descriptor but the database (ProStructuresMaterial.mdb) contains a mass value (this is the same database that the application ProStructures uses but when you get mass of a member in ProStructures is uses the value in the database, if you change the grade, it changes the mass) see image Mass_3

    In image Mass_4 you can see that there are different weights for different materials, these are the Structural | Material descriptors, but that value is not used to calculate the mass.

    Hi David, could you explain usecases that are affected or would require the mentioned features?
