The work that continues after v0.12.0 (published 2026-10-31), moved from the 0.12.0 milestone when 0.12.0 shipped. Geometry a BIM user can rely on, measured per category against Revit's own exports on the reference pack (#407): wall bodies against their type's layers (#358) and walls Revit draws cut (#1067), openings (#227), room boundaries (#90), roofs over T and U footprints and roof cases with no oracle (#884, #885), stair flights (#357) and aggregates (#323), beams (#94), MEP (#96, #869), the sketch-to-solid pipeline (#156), and the elements Revit leaves out by type (#309). Element data: instance and type parameters with units and precedence (#35, #155), the element-record fields that carry them (#223), door and window sizes where no symbol cuts an outline (#810), and ports' system classification (#834). Export time on Revit 2015 to 2023 (#1237). Each slice records baseline, improvement and residual; approximations stay labelled (#409). A slice ships in the next release that contains it.
