A Mechanical Item is an Item specialized for mechanical parts and assemblies. It carries the engineering identity of the part alongside mechanical details such as tolerance, surface finish, geometry, and manufacturing method.
When to use it
- Use it for designed mechanical components such as housings, brackets, shafts, and mechanical assemblies.
- Choose it when mechanical characteristics are relevant to the engineering definition.
Key information
- Item identity: number, name, description, revision, and state.
- Mechanical definition: fit tolerance, surface finish, and geometry type.
- Manufacturing context: manufacturing method and cycle time where used.
Common relationships
- Subitem places the mechanical part in a parent engineering assembly.
- Drawing connects it to the managed drawing used to communicate its design.
- Material connects the item to a managed material record.
Working with this record
Identify the part consistently and keep the drawing and mechanical description aligned with the revision being reviewed. Record quantities on the assembly connection. Review parent usage before replacing an existing design with a newer revision.
Example
Housing H-100 is a Mechanical Item for the pump casing. Its surface finish and fit tolerance describe key mechanical expectations. It is connected to Housing Drawing D-100 and to the material definition used for the housing.
Choosing the right type
Choose Mechanical Item for a mechanical engineering definition. Choose Material for the manufacturing input, Document for an explanatory specification, and Standard Part for a standardized component that is reused.
