Tap a name to make it the active layer (new objects land there); double-click, right-click or long-press it to rename. Checkbox shows/hides the whole layer.

Pick a component, then tap in the model to place it. Esc cancels.

Needs a running ComfyUI with CORS enabled:
python main.py --enable-cors-header "*"

Each storey exports as its own IfcBuildingStorey; elements are contained in theirs.

Types export as IfcWallType/IfcSlabType/… with IfcRelDefinesByType links.

Volumes/areas also export into the IFC as IfcElementQuantity on every element.

Zone export: select exactly one object to act as the spatial boundary; everything whose centre lies inside its bounding box is exported.

Taper draws the far end in, chamfer cuts the arrises, segments round the cut (1 = straight 45°). Recess steps all four sides in once the shoulder is reached — a rebate for glazing or a reveal; a recess with the shoulder left at 0 insets the whole bar instead. A draft angle is a slope, so it wins over the taper distance and follows the length as you drag; type a taper instead and the angle clears. Values apply live: to the extrude in progress, to the selected (or last) bevel solid, else to the next one. During a drag the arrow keys step chamfer (↑↓) and taper (←→), Shift for fine; type length;taper;chamfer;segments for all four at once. A chamfer larger than half the profile’s shortest edge is clamped, and the status line says so.

Tap a box, type one letter (or clear it). Fixed: Space Select · Shift+Z Zoom Extents · G Group · Ctrl Z/Y/S/A/D. Conflicting letters move to the new tool.

Extensions are scripts using the same API as the Scripting Console (model, draw, ui…). Enabled extensions run automatically when the app starts. They are stored in this browser.
