Component Weight Transfer
In the Modeling environment/Main Assembly, this journal transfers weight information (weight attribute - EW_Body_Weight) from solid bodies to components. Summarizes all component weights to assign a Total Assembly Weight attribute to the Main Assembly, excluding weights of underlying components. To be used exclusively with the original - EW_Material_12mm Plywood. When you assign one of NX's built-in materials, this function occurs natively.
