Revit 2027 New Feature: Wall Hosted on Walls

Why It Matters

Hosted walls accelerate BIM workflows by automating joins and movements, yet teams must address family‑alignment issues to maintain detailing accuracy.

Key Takeaways

• Host a wall directly on another wall in Revit 2027.
• Hosted walls inherit movement, eliminating manual constraints in models.
• Offset parameter controls distance, but >150 mm disables automatic cuts.
• Auto-join creates openings automatically when hosted wall is activated.
• Family elements may misalign; trims and frames can conflict.

Summary

Revit 2027 adds a new “hosted wall” capability, allowing users to attach one wall directly to another. The feature builds on recent enhancements that simplify mixing wall types, such as segment‑by‑segment and room‑based wall creation, and is accessed via a dedicated tool in the wall‑creation workflow.

When the hosted‑wall option is enabled, the new wall automatically joins to the host, inheriting its movement and generating openings (e.g., windows) without manual constraints. Users can set an offset value to position the hosted wall precisely; however, offsets exceeding 150 mm suppress the automatic opening cut. The contextual menu also offers an auto‑join toggle, streamlining the process.

In the demo, activating “hosted wall” and “auto‑join” instantly creates a window opening that follows the host when moved. The presenter notes a caveat: wall‑hosted families like doors and windows do not account for the extra wall’s thickness, potentially misaligning trims and frames.

The tool promises faster modeling and reduced file‑size overhead compared with traditional constraints, but firms must audit family behavior to avoid detailing errors. Early adoption can improve coordination in complex wall assemblies, provided the limitation on thickness is managed.

Original Description

It is now possible to host walls on other walls.
