![]() They are created by manufacturers to market their products and for architects to design faster and smarter. Furniture is the most common type of products found among BIM objects. They are intelligent 3D models of products created in BIM software with embed data of detailed product specifications. BIM objects are smaller models essential in the main project BIM model. When we talk about component models in Revit, BIM objects usually come to our mind. There is more control and flexibility managing a nested family. Rather than creating a complex family model, we can create different parts as individual families which can then be inserted into another family. Nested families are the solution to managing complex forms in a single family. This type of family is most effective to model according to the unique conditions and requirements of the project. As they are created by the users and not the system, it gives the architects and engineers a chance to create organic forms that are non-existent in pre-defined families in Revit. ![]() Therefore, we cannot export them to other projects. However, they are created directly in the project and for that project exclusively. However, they are only customizable in the family editor in Revit.Īn in-place family is more or less the same as a Component family. We can create and modify component families directly (not just limited to their Types). The only similarity between these two is that the families can be both model and non-model elements. If you understand System families, Revit Component families are very easy to understand – They are all families and Revit components that are not a System family. All families in Revit, whether they are model elements or project data, share this unique characteristic. The software system defines their properties and behaviours, hence, users cannot manipulate or ‘redefine’ them. Anything that has been built into the software – walls, doors and floor families, or even project data – cannot be deleted or edited by the users. System familyĪs mentioned above in our rectangular columns example, a System family cannot be edited. These are not to be confused with Types all three are still classifications of family in Revit. We can further categorise families based on their behaviours giving us – the System family, the Component (Loadable) family and the In-place family. That is just the definition of a Family in Revit. Revit Family Terminology Branches In A Family While working in Autodesk Revit does not necessarily mean working with BIM, Revit families are often also referred to as BIM components. We choose the type of an element (for example, a 200mm thick wall) which is in fact part of the Wall family.īuilding components are not the only Revit families available even furniture, texts and dimensions can be part of a Family. Even when you do not understand the concept behind Revit families, it is safe to say you have been using them in your modelling process in Revit. A Revit family shares the same functions and behaviours as well as an overall look, though each type in the family may have slight variations. ![]() Autodesk states that all elements in Revit are in defined hierarchies and are parts of a family. ![]() ![]() Now, it’s time to define what a family in Revit is. We cannot edit the Rectangular Column family but we can modify each type in this family. The types in this family include 300mm x 300mm rectangular columns and 600mm x 600mm rectangular columns (they may be many more types in the software). We want rectangular columns which are actually part of an uneditable system family (more about this below). Say, we want to add columns to the structure. A family can consist of more than one type, a set of values that can conveniently switch many variables of a family at once. The difference between a category and a family is that the definition of a family is less broad, i.e. Just like how all elements are part of a Category, they also belong to a defined family. To define elements and their behaviours better, we have the next level in the hierarchy – Families. The Categories are manifested in all shapes, sizes and behaviours. On the other hand, Annotation Categories are dimensions, tags, and texts. The elements in the Model Categories include elements of your model like doors, windows, beams, and walls. The most common categories a Revit user will encounter are the model and annotation categories. The first level of hierarchy is the Categories, pre-defined and uneditable. Before we dive into a definition of the Revit family, we should first understand the hierarchy in a Revit model. ![]()
