Final answer:
The types of information found on industrial prints but not on commercial prints are tolerances and precision measurements, assembly instructions and procedures, and material specifications and surface finishes.
Step-by-step explanation:
The student's question involves identifying types of information found on industrial prints that are not commonly present on commercial prints. After examining appendices for specifications, three such pieces of information include tolerances and precision measurements, assembly instructions and procedures, and material specifications and surface finishes. Industrial prints are essential for ensuring that all components are created and assembled with the required precision. Tolerances specify the allowable variations in dimensions and are crucial for functional fit between parts. Similarly, assembly instructions guide technicians on how to put together complex machinery or products, ensuring consistency and quality. Lastly, information on material specifications and surface finishes is important for the durability, appearance, and performance of the final product.
