What is the name of the list showing components used in an isometric drawing?

The correct answer is the Bill of Materials. A Bill of Materials (BOM) is a comprehensive list that outlines all the components, parts, and materials needed to complete a project, such as an isometric drawing for piping systems. It typically includes descriptions, part numbers, quantities, and sometimes pricing information, making it essential for project planning and execution in various engineering fields.

In the context of isometric drawings, the BOM serves as a reference to ensure that all necessary components are correctly identified and sourced for fabrication and installation. It facilitates communication among team members and stakeholders, allowing for accurate inventory management and procurement.

In contrast, while a Parts Inventory and a Component List may serve similar purposes, they generally lack the structured details and comprehensive nature of a BOM, which is designed specifically for project management and construction activities. An Assembly Guide typically provides instructions on how to assemble components rather than listing them systematically, and therefore does not fulfill the same role as a BOM.
