Remove Unplaced — BIMO Documentation

Remove Unplaced cleans the current Revit project by deleting spatial elements that do not have a placement location.

Find the command in BIMO > Analyze > Remove Unplaced.

When To Use It

Clean up unplaced Rooms left after removing room placement from plans.
Remove obsolete unplaced spatial elements before issuing or auditing a model.
Reduce noise in room, space, or area schedules before further coordination.

Requirements

An active Revit project document is required.
The command works on the entire current document, not only the active view.
No preselection is required or used.
Elements in linked Revit documents are not processed.

How To Use It

Review the project for spatial elements that should remain available for later placement.
Run BIMO > Analyze > Remove Unplaced.
BIMO finds spatial elements whose Revit Location is empty.
All matching elements are deleted in one transaction.
BIMO shows a completion notification.

The command does not open a selection dialog or a confirmation dialog before deletion.

What Is Considered Unplaced

The current implementation collects every Revit SpatialElement in the host document and deletes those whose Location is null.

This is narrower than checking for zero area: a placed but unbounded element is not removed merely because its calculated area is zero. At the same time, the implementation is broader than the catalog description “unplaced rooms” because it is not explicitly limited to the Room class.

Before running the command, review unplaced Rooms and any other spatial-element types used in the project, including Spaces or Areas.

Result

All matching element IDs are passed to Revit deletion inside one transaction named Remove Unplaced Spatial Elements.

Deleting a spatial element can also affect dependent tags, references, schedules, or other data managed by Revit. Review the model after the command finishes.

Warnings And Model Impact

The command permanently changes the current model state by deleting elements.
It processes the entire host document regardless of the active view or phase.
It does not ask for confirmation and does not show the number or names of elements before deletion.
It is not limited by code to Rooms only; other unplaced SpatialElement instances may also match.
Linked models are not modified.

Save or synchronize important work before running the command. Use Revit's normal review and recovery workflow if the result is not expected.

Settings, Presets And Variants

Remove Unplaced has no command-specific settings, presets, or generated variants.

Troubleshooting

Problem	What To Check
A placed element was not deleted	The command only removes elements whose Revit `Location` is `null`; zero area alone is not enough.
More than Rooms were affected	The implementation collects the base `SpatialElement` class and is not explicitly restricted to Rooms.
Elements in a linked model remain	Open the linked project and run the command there if appropriate.
The command fails during deletion	Check that the project and matching elements are editable and that worksharing ownership does not block the transaction.
No preview or confirmation appeared	This is the current behavior; review unplaced spatial elements before launching the command.

Known Limitations

There is no preview, count, category filter, phase filter, or per-element selection.
The command does not provide a dry-run mode.
The completion notification does not report how many elements were deleted.
The current catalog text describes Rooms, while the implementation uses the broader SpatialElement type.
