If you open Sustainability for an assembly with components that have not been assigned materials in the Sustainability database, a Task List prompts you to assign materials or exclude the components from the calculation.
-
In the Task List, select a component.
- Do one of the following:
- Click Exclude.
A 
symbol indicates that the component is excluded from the calculation.
- Under Material, select a Class of materials and a material Name.
The software displays the part's weight and the amount of recycled content, and a green check mark 
appears beside the component.
Optionally, modify the settings for the Manufacturing, Use, Transportation, and End of Life sections of the Task Pane. See Setting the Manufacturing Options and Setting Use Options.
You can modify settings later by selecting the material in the FeatureManager or graphics area.
- If you have defined a material for the environmental impact calculation and want to assign it in SOLIDWORKS as well, click Set Material.
- Repeat steps 1 through 3 for all components in the Task List.
The Message area turns green.
- Click View Results to initiate the environmental impact calculation.
