Families and Content
Family fundamentals
Families are the building blocks of content. Candidates must understand the three kinds: system families (walls, floors), loadable families (columns, beams, tags), and in-place families. Know family categories, parameters, and types. Understand reference planes and how they drive geometry and constraints.
Parameter types
Know instance vs type parameters, shared parameters, and project parameters. Understand how parameters drive dimensions and schedules, and how shared parameters enable tagging and scheduling across projects.
Family editor workflow
Know how to create a loadable family: choose a template, set category, add reference planes, add dimensions and parameters, then create geometry and constrain it. Understand flexing the family to test parameters.
Traps to watch
A common trap is confusing instance and type parameters: changing a type parameter changes all instances. Another is assuming a shared parameter is automatically in every project; it must be added. Watch questions on reference planes: geometry constrained to reference planes flexes correctly, while unconstrained geometry does not. Expect questions on nested families and on why a family will not load (wrong category or template).
Worked rule of thumb
Constrain before drawing. Rule: set reference planes, dimension and label them with parameters, then draw geometry locked to those planes. Flex to verify.
Content management
Understand how to load families, manage types, and keep content organized for the project.
