WEIGHT_NET
This is a template attribute. Template attributes can be used in filtering, or to retrieve data from the model to use in drawings and reports. For example, when you create a report, Tekla Structures replaces the attributes added in the report template with the corresponding object property values.
Shows the weight of the fabricated part, assembly or cast unit. The calculation formula 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 catalog, density is the value of Property: Profile Density in the material catalog.
-
If there are no cross-sections, density is the value of Property: Plate Density in the material catalog.
For parts, the net weight is not the actual weight of the fabricated parts. The profile cross section 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.
