How Families Are Created Using Revit?

Generation of families in Revit is becoming widely used day by day because it happens to be the best way to save project time and overall expense incurred on the project. It is possible to create numerous families according to client's specifications and standards which can be utilized in future projects. Often families are created in advance of the commencing of project or occasionally at the time when such component are necessary during the project. Every component being utilized belongs to any of in-built family like door, windows, curtain etc. Revit also enables us to generate the families of according to our requirements which are referred to as customized families. You can store these families the external libraries utilized in Revit which can be utilized according to the requirements. Customized families can be built in Revit by importing pre-existing 2Dcad files into Revit and employing 3D feature in it utilizing different tools supported with Revit.

Revit uses.RVT files for compiling BIM Models. Various 3D Objects such as walls, floors, ceiling, stairs, roofs, windows, doors, etc are essential for construction of building. These objects are knows as families and are saved in files with.RFA extension. These.RFA files are then imported to the.RVT. These families are the pre- built reusable components incorporated within a Revit model. Families or Components function in the same way as blocks in AutoCAD. In AutoCAD only the distance between two entities is determined whereas in Revit if the dimensions are altered than the dimensions of the component associated with it are also modified.
Even though all families vary and some of these are extremely intricate, the process for developing the families in Revit remains the same. Following is the step by step process employed to create component families in Revit.

€ Selecting Family Template:
Component Families in Revit are intricate objects and they are built and kept in distinct categories, however the key element for them is their characteristic and interaction with various Revit families. Therefore, it is crucial to choose the appropriate template for the these families.

€ Figuring out vital Parameters:
It is possible to regulate dimensions, materials, etc along with other specifications like instance, types, etc in component families in Revit. It is essential to identify if the parameters ought to be utilized in dynamic schedules or tags. The generation of Revit Families will become hassle-free when the particular parameters are known and structured.

€ Developing Geometry of the Model:
Every component family incorporates essential reference planes and curbing geometry which are docked to the parameters. This phase is extremely important to build a completely functional component family. It becomes really easy to build curb model geometries after developing couple of simple families as practice.

€ Setting up Rules for Visibility:
Revit's visibility graphic override feature is not compatible with every component family. It is crucial to allocate an individual definition of visibility rules for every object in component family in Revit.

€ Creation of Family Types:
Every family ought to include numerous types to make dealing with Revit rapid and convenient. For instance, building various window types makes selection for a new kind with diverse parameters less complicated as compared to acquiring a certain component family for every window.

Thus, above mentioned are some of the basic steps required to create Revit Familes.
