Calculate Underlying Levels
If this alternative has been selected, the weight of the underlying levels in the part structure will be calculated. However, only the main part's weight will be saved during the calculation.
Include Parts with Fixed Weight
This alternative is selected by default. Fixed weight is used for parts where the material is processed so that the finished product's weight is less than the raw material's weight. For these parts you enter the weight manually and the weight will not be overwritten during the next calculation.
