In plan view world-Z collapses to zero on screen, so every wall-edit icon anchored on the floor — the projected 3D cursor, wall endpoints, wall-to-wall corners, IfcRelConnectsPathElements connection points — projects onto the click target it represents. The result on a typical extend / split / unjoin action: the icon sits on top of the cursor crosshair (or the corner the user wants to click), defeating precise positioning. Add shared ``gizmo.top_down_clearance(context, billboard_rot)`` to bim/module/drawing/gizmos.py: returns a screen-up Vector in top-down view (cosine cone around world Z, matching ``is_view_top_down``) and a zero Vector elsewhere, so call sites apply it unconditionally before ``billboarded_at``. Default distance 0.4 m aligns with the inter-icon stack spacing already used by GizmoWallJoinIntersection so single icons and stack bases land at consistent screen-up positions when multiple groups render around the same wall endpoint. Apply at the seven wall-edit anchor sites: * GizmoWallEdition cursor stack (top-down branch only — non-top-down already stacks along world-Z at structural points clear of the cursor). * GizmoWallExtendVertically (single icon at wall origin endpoint, active-object Z elevation). * GizmoWallJoinIntersection corner stack base + merge midpoint. * GizmoWallUnjoinSingle link-toggle pool (one icon per IFC path connection, previously sitting exactly on the connection point). * GizmoWallFilletReedit pen icon at fillet corner. * GizmoWallFilletToggleOpenings. The clearance is a pure visual offset — bound operators still read the world-space anchor (cursor / endpoint / connection point) at execute time, so the action's target is unaffected. Also tighten GizmoWallUnjoinSingle: gate poll on ``props.is_editing`` so the link-toggle icons only surface during the wall edit lifecycle (matching every other edit-row icon), and downsize them via a new ``ICON_SCALE = 0.35`` constant since 16 of them at default scale cluttered the viewport on path-heavy walls. ruff + black clean. Wall gizmos test lane 14/14 pass. Generated with the assistance of an AI coding tool.
IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
