Revit Family creation is a part of Building Information Modelling life cycle. “Components” that are developed during the process of creating a virtual construction model are known as “BIM Components”. Since Revit is one of the most popularly used software in BIM modeling, they are known as “Revit Families”.

Today we will talk more about how the families are created and used based on the project requirements. We can perform BIM family creation using “Revit family editor tool”. This tool is extremely useful and a better way of creating BIM Revit content. The components can be created without a lot of restrictions and utilization of parameters become easier with the help of the family editor utility. Newbies using Revit for the first time can easily use this tool to create a seamless user interface. In order to understand the functionalities of this tool, we will need to understand the overall “Revit Family Creation” process.

Any BIM model that we develop in 3D is actually comprised of a group of “Revit Families”. Each and every element that we develop is actually a part of the BIM family or library. They are small components or bigger components bifurcated into different categories. These categories cannot be modified or changed as they are pre-defined. These categories can be defined discipline wise within the Revit software. The families will be defined as elements within these categories. They can be walls, doors, windows with different variations like a single door, double door etc. There are three types of Families

System Family or default families: System families are the families that are inbuilt in the Revit software. These families cannot be edited or modified at all as they are pre-set within the software. These families are a system built and cannot be used for multiple user interface or models. The system families cannot be deleted from the software. These families are used for developing basic 3d models where we need to only show the placements. System families. Though system families have different properties or features, basic root characteristics remain same

Loadable Families: Loadable families are one of the most preferred and commonly used for [https://www.teslaoutsourcingservices.com/bim-services.php BIM Modeling]. Compared to system or default ones, loadable families are a better option. These families actually can be created independently of any specific user interface or model requirement. These families can be used in different user interfaces, many other models with similar setups and can also be sold as individual families to manufacturers or product design companies. Loadable Revit families are also known as component families. BIM Engineers or [https://www.teslaoutsourcingservices.com/revit-family-creation.php Revit Family Creation Services] provider can create, edit or delete the families. They can also assign parameters so that the family can adjust itself based on the user interface or model requirement. It is easier to customize the loadable families using a family editor.

Loadable families can be nested and parametric in nature. We can add restraints and parameters as much as we require based on the requirements. As mentioned earlier, the Revit families can have variations with each family. These family types can be added later in the project with the help of family editors.

Parameters that control the appearance of a particular family can be added to it. Some of the parameters are dimension, instances, material, visibility etc. When a family is inserted and loaded on to a model the user can modify the family to suit the overall project environment. This is one of the most prominent features available in Revit. You can use the family editor feature and can ease the utilization of BIM content or families.

In place families: In Place families is a family type that is somewhat similar to loadable families however there is one major difference. In place families cannot be created or used as standalone families. However these families can be developed, edited and placed within a model that the in place family is hosted in. There will not be any separate .RFA file that is created while working on in place families. In place families are easier to create and can serve the purpose efficiently if the model is unique and specific in nature. In case you are sure of not utilizing the families in any other project in-place families are a better option than system or default families. You can create Revit families like wall, doors, windows, roofs etc. using in place families.

Since we are talking about families, we can also talk about Nested families. Nested families are actually used when a BIM Modeler wants to build complex geometry using multiple forms. Nested families can be built using family editors too. Sometimes owing to the complexities of the geometries it becomes important to create nested families. Nested families can also be defined as families inserted within families. If the family is complex, we can always create simple families and insert them into another family. By creating Nested Revit families, we can operate and manage families with good flexibility and control.

When we work with BIM family creation or load the families, we should keep in mind that these families are a part of a particular category. Hence every element of the particular BIM content will be a part of the sub category in a family. These elements assist in visibility of the family along with good flexibility of changing the geometry when required. You can have sub categories of windows, doors, floors etc. Visibility parameters can also help in managing the elements easily just like the subcategories. It helps us to place a particular family in a particular project environment to check how the component is visible. The user can always switch on and off the visibility parameters based on the requirements.

Before the advent of Revit, such components were drawn in AutoCAD. There were “AutoCAD” blocks that were used to depict any geometrical component in a drawing. AutoCAD blocks cannot be modified or changed according to any project or used in any other project. It is project specific and can be managed only within a project. They can be created once and placed in multiple locations within the specific project. Revit Family creation, basically work on a different platform and offer us components that can be used in many ways. These can be fully parametric or generic in nature. If we talk about an example, drawing a door as a block and creating it as a BIM component or family will be very different. Revit works with a parametric approach while AutoCAD works with 2D approach. When we have to place multiple doors in model, we can create one family and keep modifying it according to the requirements of different doors across different locations instead of just placing a simple block or 3D geometry. You can have multiple variations of single window. We can create nested families that can provide you with dynamic models. They can also give you an excellent grip over the BIM Models that you create enabling you to change them later depending on the other requirements.

Conclusion: This article has mostly covered majority of topics on BIM Families or Revit family creation. Readers can understand the functionalities of BIM components this article. BIM content creation is one of the many functionalities in virtual construction modeling that ensures cost effective and seamless construction processes.
