Shows the weight of the fabricated part, assembly or cast unit. The calculation formularule stated in a mathematical language

Formula is part of an equation.

depends on the object:

  • For parts, returns the net weight, which is the actual weight of the fabricated part. Rounding of the profile corners are not taken into account.

  • For bolts, returns the bolt weight, and for other objects a zero.

  • For assemblies, returns the sum of part weights.

The calculation is based on part volume and density of material. The density value used in the calculation depends on the profile cross-sections:

  • If cross-sections are defined in the profile catalogcatalog that displays profiles and information on the profiles

    In addition to the available profiles in the respective Tekla Structures environment, the user can add fixed or parametric user-defined profiles to the profile catalog. It is also possible to import profiles to the profile catalog.

    , density is the value of Property: Profile Density in the material catalogcatalog that displays material grades and information on them

    By default, the material catalog contains standard, environment-specific materials. The user can add, modify, and delete material grades.


  • If there are no cross-sections, density is the value of Property: Plate Density in the material cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.



For parts, the net weight is not the actual weight of the fabricated parts. The profile cross sectiongeometrical form of a part sectioned perpendicular to its axis

is calculated using straight angles, so the roundings in the corners are not taken into account (unless you are using the advanced option XS_SOLID_USE_HIGHER_ACCURACY ). This causes significant difference between the calculated and the actual weight especially when big cross sections are used.
