Four concerns that together make the cursor-anchored gizmos
(extend_x_gizmo, extend_z_gizmo, split_gizmo on GizmoWallEdition)
fully functional and visually informative without entering parametric
edit mode first:
* Drop the props.is_editing gate in _update_cursor_gizmos. The three
bound operators (bim.extend_wall_to_cursor,
bim.extend_wall_height_to_cursor, bim.split_wall_at_cursor) already
poll on wall-selected and commit any pending wall edit before
acting, so single-click without entering edit mode is now the
canonical flow. Matches gizmos-8088's always-on behaviour.
* Register GizmoWallEdition instances in a per-region weakref map
(_active_instances) populated at setup_element_specific_gizmos
time. The WallGizmoPreviewDecorator dereferences this map to read
live is_highlight state off the cursor icons. Without the
registration its _cursor_icon_hovered always returned False and
the hover-gated GPU previews silently never drew. Mirrors the
same pattern already in place on GizmoWallJoinIntersection.
* Add post-operator resync to all three cursor operators
(_maybe_resync_wall_props_from_ifc for the single-wall split /
extend-height paths, _resync_walls_after_mutation for the
selection-wide extend-X path). Without this, props.length /
props.height stayed stale after the operator ran, so the
orientation flips _apply_wall_extend_flips computes from
cursor_local vs wall dimensions kept using the pre-extend values
until the next selection change. Matches gizmos-8088's pattern.
* Hover-gated GPU previews per icon:
- extend-X: filled Z=0 floor quads spanning the wall's offset to
offset+thickness Y band, visible from plan view without side-
view clutter. Grow case (cursor beyond either endpoint): one
green decorator_color_selected quad over the extension. Shrink
case (cursor inside extent): green quad for the portion that
REMAINS + red decorator_color_error quad for the portion the
operator REMOVES.
- extend-Z: vertical lines at the cursor's projected X in the
wall's y=0 reference-line plane. Grow case (cursor above wall
top): one green segment from z=height to z=cursor.z. Shrink
case: green from z=0 to z=cursor.z (REMAINS) + red from
z=cursor.z to z=height (REMOVES).
- split: one red vertical line at the cursor's projected X from
base to wall top — the cut plane.
Quads use QUAD_ALPHA=0.25 so the underlying wall body stays
visible.
* New module-level _fill_quads_alpha helper next to
_stroke_lines_alpha, plus a per-decorator _fill convenience method
and a _wall_floor_quad corner builder.
Modal-active gizmo hiding (is_gizmo_hidden_by_modal) is preserved.

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.
