EZ Ceiling Grids

Use a reflected ceiling plan, floor plan or supported isometric 3D view in which the ceiling model pattern can be measured. Ceilings without a model surface pattern are skipped.

Ceiling model

Choose the host or a loaded link instance. The selected instance’s transform is used, including moved or rotated links.

Every ceiling whose type name contains

Uses comma-separated, case-sensitive type-name keywords; initial examples are ACT, APC, Grid. A matching type still needs a usable model surface pattern.

Phase and Levels · All / None

Restrict the filtered ceiling batch by phase and checked levels. All checks the levels; None clears them. Verify the scope count after choosing the source.

Only the ceilings I pick · Pick / Clear

Uses explicit ceiling selection instead of the type-name batch. Pick returns to Revit selection; Clear empties the picked list. A picked ceiling still needs a valid pattern.

Dimensions are entered in project units and must be positive and no greater than 1 ft. These are member sizes, not tile spacing; spacing comes from the ceiling pattern.

Main runner height

Height of members following the wider-spaced direction: 4 ft spacing in a 2×4 pattern. A square pattern uses its first direction. Initial height is 1.6875 in, converted to project units.

Cross tee height

Height for the other pattern direction; initially 1.5 in. Choose the member profile size appropriate to the project’s modeled system.

Edge member height

Height for members following the ceiling outline; initially 0.875 in. Perimeter members follow the boundary rather than a repeating tile spacing.

Grid width

Face width of all members and thickness of the generated basic-wall type; initially 0.9375 in. This affects modeled geometry, not the source ceiling’s hatch spacing.

Wall type name

Defaults to Ceiling Grid. If missing, the tool derives a basic-wall type and sets its thickness to Grid width. Grid walls are not room-bounding. Flat grid lines use walls; sloped and perimeter geometry uses adaptive members.

Replace grids from an earlier run on the same ceilings

Reconciles previously generated members for the same ceiling identities before creating the new grid. Enable for a deliberate refresh after layout changes; check ceiling scope to avoid unintended replacements.

Put grids on workset · Existing / Add a workset / New name

Choose an existing host workset or Add a workset… and enter a new name. A duplicate name must be selected from the existing list. New worksets are created with the grids, never during Preview. Unchecked uses the active workset; the controls are disabled in non-workshared projects.

Preview follows the actual pattern origin, directions and clipped ceiling boundary. Missing measurements must be resolved rather than replaced with an assumed grid.

Preview…

Analyzes the ceilings without creating members. Review each row and the total before approving.

Preview · Ceiling / Id / Level

Identify the source ceiling by name, element ID and level. Use these when checking a skipped or unexpectedly large row in Revit.

Preview · Main runners / Cross tees / Edges / Length

Read-only member counts for each class and the combined modeled length. Compare against a representative ceiling outline and tile pattern; these are analysis outputs, not editable quantities.

Preview · Status

Explains whether a ceiling is usable or skipped, including unavailable pattern measurement. Correct the source/view/settings and preview again when needed.

Back

Returns from preview to configuration without creating grid members.

Create grids

Creates the analyzed grid members. The preview button proceeds with the reviewed configuration; the main button starts from the current settings. Read the final created/skipped counts and inspect a sample.

Cancel

Closes configuration without model edits. In multi-ceiling progress, cancellation stops after the current ceiling and retains completed ceilings; the completed operation can be reverted with Revit Undo.
