Can you join a floor and a wall to remove the line between them in Revit?

Short Answer

Yes — in Autodesk Revit, you can join a floor and a wall to remove the line between them by using the Join Geometry command. This is the most common professional method for cleaning up intersecting model edges in sections and details. It only works when the elements truly intersect and their geometry is compatible.

What You Need to Know Before

Warning: If the wall and floor do not physically overlap, Revit will not remove the line even if you use Join Geometry. Also, joined geometry can affect material priorities, cleanup behavior, and how junctions display in views.

How to Remove the Line Between a Floor and Wall in Revit

• Command: Join Geometry

• Shortcut: No default keyboard shortcut

• Quick Steps:

  1. Go to the Modify tab on the Ribbon and click Join Geometry in the Geometry panel.
  2. Select the wall, then select the floor.
  3. If the result looks wrong, use Switch Join Order from the same panel to reverse the cleanup priority.

Variables & Settings

• Key Setting: Switch Join Order

• Expert Setting: This option changes which element controls the visible cleanup at the intersection. If the line remains or the cut looks incorrect, switching the join order often fixes the display without remodeling either element.

Why it Fails

• Cause 1 (Geometry): The wall and floor are not actually intersecting, or one element stops short due to offsets, constraints, or edited profiles.

• Cause 2 (layers/Locks): The floor or wall may be in a linked model, within a design option, or constrained in a way that prevents proper joining or visible cleanup.

• Cause 3 (Command/Logic): Revit may join the elements but still show edges because of view detail level, component layering, or the current join order.

Quick Fix & Best Practice

• Quick Fix: Use Join Geometry, then immediately try Switch Join Order if the line does not disappear.
• Manager’s Verdict: Use Join Geometry for standard wall-to-floor cleanup in live building models, but avoid overusing joins in complex assemblies where they can create display confusion or coordination issues later.

FAQ

Can Join Geometry work in plan and section views?
Yes, but the visible result depends on the view and how the elements intersect.

Why is the line still visible after joining?
The elements may not overlap enough, or the join order may be wrong.

Can you join elements in a linked Revit model?
No, you generally cannot use Join Geometry across linked model elements.
