Create the blinding layer under pad footings, pile caps, mats and strip footings in a single sweep — instead of drawing a 100 mm offset floor under each one by hand.
There's no command in Revit that generates a blinding layer under a footing — engineers draw a brand-new Floor by hand for every footing, offset the boundary by the lean-concrete width, set the elevation and thickness by convention, then repeat the exact same steps for every one of the hundreds of pad footings on a project.
Pad footings, pile caps, mats and strip footings on a typical building easily run into the hundreds — each one needs its own blinding layer, and drawing them by hand one at a time adds up to a large amount of repetitive work.
Trace the boundary to match the footing's shape, offset it outward by the lean-concrete width, drop the elevation below the footing's underside, then pick the floor type and thickness — the entire sequence repeats unchanged for the next footing.
Nothing enforces the blinding offset and thickness to the Vietnamese-standard convention — each engineer types it from memory, so the layer ends up inconsistent across zones modeled by different people, and the mismatch only surfaces at QA.
For a stepped or sloped mat footing, eyeballing the correct boundary and bottom elevation at each zone easily leaves gaps or overlaps between blinding patches — a mistake that only shows up when someone cuts a check section.
No add-in on the App Store auto-generates a blinding layer — the common approach, even with other general-purpose foundation add-ins, is still modeling a new floor by hand under each footing, using an in-place family or a slab edge. Blinding Creator scans the whole model, resolves the floor type and elevation by convention on its own, and processes footings in batch:
