Lean Concrete — host scope, type and edge extension
Open BimSpeed.STR → Model → Create Lining Concrete. The tool derives blinding geometry from floors, foundations or beams. It does not convert an ordinary Floor Type into a Foundation Slab Type. Start with one actual host in a project copy.
| Control | Setting and verification |
|---|---|
| Select | Uses eligible preselected floors/foundations/beams, or asks for a Revit selection when empty. Finish ends picking. |
| All elements in project | Collects enabled categories. Use Select for an initial focused run. |
| Floor / Foundation / Beam | Enables each host category; several categories can produce different geometry paths. |
| Active View | In the reviewed implementation, beam/foundation collectors use the view while the floor collector still uses the document. This is not a guarantee that every floor is view-limited. |
| Offset | mm, reviewed default 200. Extends the blinding edge; thickness comes from the type. |
| Type | Select a Structural Foundations FloorType. An empty list requires a suitable foundation slab type in the project. |
| OK | Confirms the dialog and starts processing. A progress indicator does not establish success for every host. Cancelling/closing does not generate blinding. |
Compare 100 and 200 mm offsets on equivalent hosts. Measure the edge extension and inspect bottom elevation, type, thickness, material and volume in Properties. Increasing Offset does not increase thickness. Check openings and re-entrant corners for invalid boundaries.
Select a newly created blinding element, rather than its original host, and compare actual counts and host-reference parameters. Do not assume a repeated run updates existing output; check duplicates. Undo, correct the inputs, save the RVT and reopen it for inspection. Remembered settings are separate from a saved result model.
Observed Revit images
Captured in Revit 2024 on a project copy using tool windows opened independently. UI screenshots do not establish the complete ribbon/picking/generation flow. Click an image to open the unchanged original at full resolution.
- Use selected elements or the project scope; category controls depend on that mode.
- Offset in mm and blinding FloorType. A 100 mm type is selected, but no blinding was generated.
- OK continues the workflow; it does not establish successful output.
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 Vietnamese/English windows, scope, category controls, offset and types were reviewed on a project copy. Blinding was not generated in this review. The selected 100 mm type is an available input, not generated output.
