To create a Revit Family the file can be submitted in various file formats or softwares. The model is submitted in one of two file formats: IFC or IFX (xml format) and then converted into a Revit model. The format establishes international standards to import and export building objects and their properties.
It provides an interoperability solution between different software applications. IFC (Industry Foundation Classes) is a neutral, open file format specification that is not controlled by a single vendor. RTE & RFT (Revit Family Template) are family templates to make a standardized template for a company. They are used to fully render 3D views in design projects & they contain various building modeling data like images, plans, sections, project settings, etc. RVT is associated with the project files of a Revit Family. A family is created in RFA (Revit Family File) file format in Revit. The different file formats in which a Revit family can be provided are RVT, RTE, RFA, RFT, IFC. Our Revit experts embed BIM objects and metadata including product literature, standard details, technical datasheets, NBS specifications, model number, and warranty information in the product catalogs.Īll the above-mentioned stakeholders can ask for a Revit Family in their choice of file format/extension. For example, if the height of a door in a family is changed once, heights of all the doors of the same type throughout the project get automatically updated.īSI is providing with a BSI kitemark certification that provides assurance to specifiers and customers that BIM Objects and the associated data are accurate in their representation. The concept is known as being parametrically-aligned. Any changes made to a particular type are updated throughout the entire project. Each family can have multiple types such as different sizes, materials, parameter variables, etc.
All Revit elements belong to a family and the best way to think about families as a collection of like items sharing the same overall look and behavior.įamilies are enriched by common attributes, parameters, properties, article number (SKU), and pictorial representations. Therefore, the next level of the hierarchy after Category is the Family. Annotation: Text, Dimensions, Tags, etc.Īll the above-mentioned category items come in all shapes, sizes, and behaviors.Model: Walls, Windows, Stairs, Beams, Doors, etc.At the highest level of this hierarchy, are Categories – model and annotation.
There are three types of families – system families, component families, and in-place families and they all fit into a clearly defined hierarchy. ifc) of their choice.Įverything in a Revit is a part of a family. The family describes the basic geometry of the element, the behavior/relationships of the geometry, and defines the element’s parameters.”Īt United-BIM, our Revit family creation and maintenance services provide our clients, such as architects, engineers, building product and furniture manufacturers, detailers, facility managers/asset managers, and suppliers with customized Revit families or BIM objects and we can provide the product data in the format (.rfa.
Subject Matter Expert, Autodesk in his blog titled “ Your guide to understanding Revit Families” states that Revit families are at the core of Revit, creating Revit Family is same as writing DNA code for an element and quoting further “Simply: the family contains the DNA of how to make an element in Revit, and when you author Revit families, you are writing the DNA code for an element. It is a design and documentation software program widely used by the AEC professionals, building product and furniture designers and detailers, and facility and asset managers. As a result, the biggest benefit is ‘Speed with Accuracy’ (along with the reduced cost of failure) for the project that can be achieved with Custom Revit Family Library.Īs we all know, Revit is a Building Information Modeling (BIM) authoring software built by Autodesk. The biggest advantage of custom Revit BIM family or library is, any change to a family is updated and permeated throughout the project file where this particular family is being used. Structural Precast Modeling and DetailingĬustom Revit Family Library (aka BIM Object or BIM Content) as the name suggests is a process of creating a customized family library of building materials or products or objects to achieve many-fold business objectives such as spatial planning, design analysis, cost estimation, product selection, and facility management.
