If you work with Revit MEP, you know how quickly diffuser tags can clutter a view. A room with several identical air terminals can end up with multiple tags stacked on top of each other, making it harder for engineers, reviewers and contractors to read your drawings.

In this post, you will discover how to solve that problem by creating typical tags for identical elements in your HVAC layout. Even better, you will see both the manual method inside Revit and a fully automated workflow using Tagitize.

Why Typical Tags Matter in MEP Design 🔧

Typical tags help you present information clearly without overwhelming the drawing. Instead of tagging every diffuser separately, one tag can communicate that multiple terminals share the same airflow and specifications. This results in:

• Cleaner HVAC layouts
• Faster reading and review
• Reduced annotation work
• More consistent documentation across the project

This workflow is especially valuable when working on large buildings where identical elements appear hundreds of times.

What You Will Learn in the Video 📹

In the tutorial, you will see:

• How to create a custom tag family for typical tags
• How to add shared parameters for typical counts
• How to ensure only truly identical air terminals are grouped together
• How to manually assign typical numbers
• How to automate the entire process using Tagitize
• How the plugin groups elements by family, type, airflow and space
• How to adjust grouping distance to control how large each typical group becomes
• How to use the same automated process to tag ducts and other MEP categories

The video walks through each step slowly and clearly so you can apply the techniques on your own project.

Automating Typical Tags with Tagitize ⚙️

While the manual method works, it can be time consuming on larger projects. This is where Tagitize becomes incredibly helpful. With a single click you can:

• Group identical air terminals by space
• Assign accurate typical counts
• Place tags automatically in tidy positions
• Regenerate tags instantly when design changes
• Apply the same logic to ducts or other categories

If you want to reduce repetitive annotation work and make your drawings more readable, this tool will become one of your favourites.

Final Thoughts 🌟

Typical tagging is a small improvement that can create a big difference in your Revit documentation. Whether you choose the manual workflow or the automated approach, the end result is a cleaner, clearer and more professional HVAC layout.
