Development of families in Revit is becoming popular day by day as it definitely is the best way to save project time and overall expense incurred on the project. It is possible to create various families according to client’s specifications and standards that could be utilized in future projects. Every component being employed belongs to any of in-built family such as door, windows, curtain etc.
Revit also allows us to generate the families of in accordance with our requirements which are termed customized families. You can store these families the external libraries utilized in Revit which can be implemented as per the requirements. Customized families can be built in Revit by importing pre-existing 2D cad files into Revit and applying 3D feature in it using different tools supported with Revit.
Revit uses .RVT files for compiling BIM Models. Different 3D Objects like walls, floors, ceiling, stairs, roofs, windows, doors etc. are crucial for construction of building. The objects mentioned are known as Families which are then saved in files with .RFA extension. These .RFA files are consequently then imported in Revit in the form of .RVT. These families are the pre- built reusable components amalgamated within a Revit model.
Following is the comprehensive process employed to develop component families in Revit:
Choosing Family Template:
Revit Families comprises of components which are intricate objects and they are built and saved in distinct categories. Importantly the key element for them is their characteristic and collaboration with different Revit families. Therefore, it is essential to choose the suitable template for these families.
Reckoning out vital Parameters:
It is possible to manage dimensions, materials besides other specifications such as instance, types, etc. in component families in Revit. It is important to identify if the parameters ought to be utilized in dynamic schedules or tags. The generation of Revit Families becomes hassle-free when the specific parameters are known and structured.
Developing Geometry of the Model:
Every component family encompasses essential reference planes and curbing geometry which are docked to the parameters. This stage is extremely important to generate a completely functional component family.
Revit’s visibility graphic override feature is not compatible with each and every component family. It is imperative to allocate an individual definition of visibility rules for every object in component family in Revit.
Creation of Family Types:
Revit Families are of three types namely System Families, Loadable Families and In-place Families depending on the elements and components and project requirements.
Thus Revit Families forms a crucial aspect in construction which assists in developing effective Revit Structure.
