Advantages of Revit Family Creation in BIM Technology


Similar to biological families, Revit families follow a certain order. For instance, a door is a ‘category’ of different components. There are different kinds of doors, and these different kinds of doors are different ‘families’. An example of a ‘family’ name would be a ‘flush door’. Within the family of the flush door, there are options for the flush door, based on dimension, material, etc. A flush door of a particular dimension is a ‘type’ of flush door. All the elements in a project’s design are created using families, including walls, roofs, doors, columns, beams, trusses, windows, fixtures, annotation, mechanical components, plumbing fixtures, lighting fixtures and other detailed components, and they can be created using Revit for BIM (Building Information Modelling) requirements in architectural design drafting.



Revit family modelling within the BIM context provides a range of advantages, namely:

  • Improved layout plans
  • Increased communication of plans
  • Impressive Revit 3D modelling for marketing
  • Detailed scheduling
  • Customisation of projects

The creation of BIM models requires the extensive use of families. Walls, doors, windows, stairs, etc. may be of multiple types in the same project. A prime advantage of Revit families is that any change to a type will be updated in every instance of that type throughout the project design. For example, when the height of a window type is changed in one place, all windows of the same type will be modified instantly and automatically throughout the entire design.

The intelligent model-based process of BIM technology helps plan, design, construct and manage buildings and infrastructure and results in delivering specific outcomes with time and cost savings. Revit families and BIM content can be created for architectural, structural, mechanical, electrical and plumbing design. The process to deliver Revit families with high standards includes:
 
  1. Selection of the family template
  2. Planning the parameters
  3. Creation of the model geometry
  4. Assigning of the object subcategories according to requirements
  5. Setting up visibility rules
  6. Creation of family type

Revit allows created families of components to be stored and reused in other projects. They can be used as reference material by architectural designers to show prospective clients.

Builders, manufacturers, designers, engineers and other stakeholders in a project are dependent on model creation services for intelligent and parametric models that can host a complete group of components or equipment for BIM construction. Besides displaying the parameters of actual equipment and geometric components of windows, boilers, columns, etc. through graphics, Revit family modelling has other advantages, such as:

  • Formula and imported data result in effective component design
  • Regardless of size and design, the models created are accurate
  • Resizing of models is both possible and economical
  • Relationships and coordination between various elements of a unit are maintained
  • Enabling building analysis and estimating

Revit modelling can create additional items like curtain wall panels, furniture, plumbing fixtures, electrical fixtures, machine parts, elevators and HVAC pumps. Family creation services include the following types:

  • Structural
  • Architectural
  • MEP
  • Building systems
  • BIM
  • Related custom and supporting content

Revit family creation, like real-life families, provides many benefits due to the inter-relationships they provide in a model. They are the driving force behind the success of BIM projects. With skilled Revit BIM practitioners available globally, accurate, cost-effective and viable project design services can be ensured.
