Materials tab

Part mass (weight)
This value is used in calculations to determine the proportion of a particular substance entered into the materials list, and the total mass of an assembly that includes the current part.
Exclude child mass/materials
This checkbox is only displayed for assemblies that show a BOM tab, as defined in the item's Part Types collection member.
When the checkbox is marked, the mass and materials reported to higher-level assemblies in roll-up reports is simply whatever is contained in this item's Part mass (weight) and Materials list. Any mass or materials contained in items on the current item's BOM are ignored.
When the checkbox is cleared, the mass and materials reported to higher-level assemblies in roll-up reports is the recursive sum of items on the current item's BOM, plus any residual amounts in the current item's Part mass (weight) and Materials list.
Regardless of the setting of this checkbox, the value reported to higher-level assemblies are excluded (reported as zero) if the Exclude item from roll-up: Mass & materials checkbox on the current item's Attributes tab is marked.
Items shown on an item's Sources tab have no effect on mass or materials roll-up calculations.
Materials list
You can identify the part's substances that should be tracked for regulatory compliance and reporting. Each line item consists of (a) the material, (b) the quantity and its unit of measure, (c) a calculated proportion (based on the Part mass value, supplied above), and (d) an optional location of the substance within the part (for instance, connector plating).
Although any unit of measure may be used, in most industries gram is the preferred measurement unit.
