When you'd merge or delete across files
A single fitting type can show up in groups across several drawings — C1 on the lighting plan, C1 on a section drawing, C1 on an as-built. If those have ended up as separate groups per drawing, you want them merged so the Totals sheet reports one consolidated row rather than three.
Cross-file actions live in Review Mode — the cross-file summary panel — and let you operate on groups and markers from multiple drawings without leaving the current view.
Where the actions live
Open the project marker summary in Detection view (the default). Every group and every marker across every drawing in the project is listed in one table — see Project marker summary.
Right-click any row to bring up the cross-file context menu.
Cross-file delete
- 1
Find the row(s) you want to delete. Select multiple with CTRL+click (or CMD+click on macOS).
- 2
Right-click on any selected row.
- 3
Choose Delete Detection (single) or Delete Detections (multi-select) . The menu item is red.
- 4
The markers are removed immediately. No confirmation dialog. UI updates optimistically.
Cross-file delete is direct — there's no "Are you sure?" prompt. The action runs immediately when you click. If you delete in error, the per-drawing undo stack on each affected file may help, but cross-file undo isn't supported. Duplicate the project before bulk cross-file work.
Cross-file merge
Cross-file merge consolidates markers from multiple groups into a single target group.
- 1
Select the source markers — single right-click on one row, or multi-select first with CTRL+click and right-click on the selection.
- 2
Hover Merge Into (single selection) or Merge Selected (n) (multi-select) in the context menu.
- 3
The submenu lists every other group of the same type across the project as a possible destination. Pick the target.
- 4
The merge runs immediately. The source markers move to the target group; the source groups are deleted if they end up empty.
What carries across, what doesn't
Cross-file merge follows the same rules as within-file group merging:
- Markers carry across.
- Target group's label, colour, and link are preserved — the source's are discarded.
- The merge isn't directly undoable.
The difference from within-file merge is scope: cross-file lets you reach groups on drawings you don't currently have open.
Type constraints
You can only merge groups of the same type:
- Detection ↔ Detection.
- Linear ↔ Linear.
- Area ↔ Area.
- Unit ↔ Unit.
Mixed-type merges aren't offered in the menu.
Working pattern — cleaning up before export
A common end-of-project cleanup:
- 1
Open the project marker summary in Detection view.
- 2
Sort by Label so identically-named groups across drawings sit together.
- 3
For each cluster of duplicates, right-click the secondary ones and Merge Into the primary.
- 4
Repeat until the table shows one row per unique label.
- 5
Now the Excel Totals sheet will show one row per fitting type with the project-wide quantity.
Alternative: use Group By: Label in the summary's group-by dropdown to visually combine identically-labelled rows without actually merging them. Use this when you want a clean view but the underlying groups should stay separate (for example, when the same label is used on different drawings deliberately).
