Align Floor To Beam — align floor boundaries to beam faces
Open BimSpeed.STR → Common → Align Floor To Beam. This edits a floor boundary against beam faces. It differs from Beam To Slab, which changes beam elevations relative to a slab.
| Control | Meaning |
|---|---|
| Auto | Select Floors after confirmation. Reference beams are collected from the active view, so make the intended beams visible first. |
| Manual | Follow the prompts to pick a floor edge and a target beam/face for a specific alignment. |
| Tolerance | mm, reviewed default 500; search range for a suitable nearby beam face, rather than a forced movement for every edge. |
| Execute | Confirms the mode and starts Revit picking. |
| Cancel | Exits without running; Esc cancels an active pick. |
Test one straight-edged slab near a beam. Measure the edge before/after. The reviewed helper searches parallel beam faces, projects edges and rebuilds vertices. Increasing 100→500 mm broadens the search and can select another nearby beam; reduce it in dense layouts. Curved or unsuitable boundaries may remain unchanged.
Inspect closed boundaries, corners/openings, Level, offset, thickness, area and volume in plan/3D and Properties. The reviewed rebuild retains boundary Z; it does not create a slab slope. Compare the Floor ID and host relationships. No change may mean an already aligned floor or no suitable face. Undo before changing tolerance, save a copy and reopen it to verify the result.
Practice input
Download the shared Revit 2024 column/foundation input. This educational file has four rectangular columns and one footing; it is not output from this article's command. Read the ZIP README/provenance and Save As before editing. It does not contain every roof, pile, link, Legend or dimension case; prepare the categories/grids/views/families required above. Screenshots on a real-project copy do not imply distribution of its private RVT.
Observed build and verification scope
The installed Revit 2024 window was opened; its right-hand action button has no visible label in the reviewed build. A separate automatic-alignment helper check on one existing floor, with 80 project beams and 500 mm tolerance, returned no change. This does not establish successful alignment or exercise manual edge/face picking. Compare actual sketch boundaries/elevations before and after, rather than relying on a bounding box alone.
A supplementary geometry trace on 23 original outer edges found three beam-side-face hits under the reviewed conditions. The step that made the helper return no change remains unresolved; this does not establish either that the floor was already aligned or that no suitable beam face existed.
