A country-specific Mechanical Equipment family template should use the measurement system and unit formatting expected in the target market. This includes the appropriate conventions for dimensions, flow, pressure, power, temperature, electrical values, and other discipline-specific quantities. Establishing units in the template ensures that family authors enter, interpret, test, and document parameter values consistently from the beginning of content development.
Object Styles govern the graphical representation of family categories and subcategories; they do not translate the family into a country’s official language. Parameter classification as Type or Instance must be determined according to the intended behavior of each value. For example, manufacturer and nominal-capacity information may be type-based, while asset identifiers or installation-specific values may be instance-based. Setting every parameter to Instance would therefore produce poorly structured content.
Project Location concerns geographical and environmental project settings and is not the principal country-standard setting for a reusable equipment family. A family template is intended to be loaded into many projects, so its numerical conventions must align with the regional standards under which the content will be authored and used.
