Revit Family Creation: Why It Matters & How to Do It

The value of custom Revit family creation lies in the level of control, accuracy, and efficiency it brings to your modelling environment.

We all know custom Revit families are parametric components created specifically to represent building elements with greater accuracy and relevance than generic content.

While off-the-shelf components save time upfront, they rarely align with Australia’s specific standards, like BAL ratings or AS 1100 drafting conventions.

Custom families, however, let you:

• Embed compliance data (e.g., fire ratings, energy efficiency) directly into components.
• Reduce rework with precise geometry that mirrors real-world products.
• Speed up documentation through pre-loaded parameters for finishes, schedules, and more.

While creating a custom Revit family takes some initial time and expertise, the efficiencies down the track are huge. For example, a Sydney firm recently avoided weeks of delays by using custom families with built-in clash detection.

Meanwhile, for your reference to keeping tabs on software improvements, checking out the Revit 2026 new feature list can show how new tools might make this even better.

How to Create a Family in Revit

Creating any types of Revit family involves a few key steps. While getting the hang of really complex, smart families takes some skill and experience, the basic workflow is pretty straightforward.

Here’s a quick look at how it generally unfolds:

1. Plan & Choose Template: Start by defining the purpose of the family and selecting the correct Revit family template. This phase sets the foundation for structure and behaviour.
2. Set Up Reference Planes & Constraints: Next, you build the family’s skeleton using reference planes. These guides where your geometry goes. Then, you add constraints (like making dimensions equal or locking them) to make sure the family behaves predictably when you change its size.    
3. Add/Define Parameters: You’ll add things like length, width, height, material, or even on/off switches to control different aspects. These can be ‘Type’ parameters (affecting all of that type) or ‘Instance’ parameters (unique to each one you place).    
4. Model the Geometry: With your framework and parameters set, you model the 3D shape using Revit’s tools (like extrusion or sweep). You then lock this geometry to your reference planes so it updates correctly when parameters change.
5. Assign Materials & Visibility: Apply materials to your geometry, which can also be controlled by parameters. You’ll also set up how the family looks in different views (plan, section, 3D) and at different detail levels (coarse, medium, fine) for clear project documents.
6. Test Flexing & Functionality: Change the parameter values to make sure the geometry adjusts correctly without breaking. This “flexing” checks that all your settings are working as planned before you use it in a project.    
7. Save and Load: Finally, save your family as an .RFA file. It’s a good idea to then load it into a test project to see how it behaves in a real setting. Check how it places, if it schedules correctly, and how it interacts with other bits.

To make sure your software is up to these tasks, it’s always wise to know how to update Revit for the best performance.

How Revit Family Creation Services Increase Efficiency?

Professional Revit family creation services increase efficiency by giving you access to specialists who build smart, parametric families for a living.

These experts understand the nuances of performance optimisation, parametric logic, and Australian compliance. What you get is not just functional models, but highly efficient, scalable assets built for real-world projects.

Simply put, your design teams have better things to do than spend hours modeling HVAC ducts. We believe you can create Revit families in-house. But it can take up a lot of your team’s valuable time, especially if you need complex BIM content or large Revit content libraries.

BIM outsourcing allows your team to focus on design development, client engagement, and innovation, rather than getting bogged down in intricate modeling tasks. Using professionals also offers scalability and helps you take on complex BIM projects without adding permanent specialist staff.

Why Interscale Is the Best Solution for Revit Family Creation?

Interscale is the best solution for Revit family creation because our approach is distinctly Australian-focused. And we don’t just create Revit families. We create BIM foundations that support long-term success across your entire project lifecycle.

What sets us apart is our complete approach. We design for every stage. For example, a LOD 300 for coordination, LOD 500 for as-built data. And our families aren’t just geometry. They’re performance-optimised, data-rich, and built to integrate seamlessly into your workflows.

Here’s why Australian firms trust us:
