Construction Documentation Lesson 4 Practice Test

Labels in three-dimensional drawings identify parts, features, or assemblies. It’s common to reuse a label to show that several separate items are the same type or belong to the same component family. This keeps the drawings clear and links all those instances to a single note or bill of materials entry. For example, every bolt of a given size in an assembly might carry the same label, with a legend explaining what that label means. Reusing labels reduces clutter and helps procurement, since one entry can cover all identical items. Of course, you can use unique identifiers when you need to distinguish particular instances, but reusing labels across multiple items is a standard practice in 3D documentation.
