Two bugs introduced in 31b571322:
- SnapObj assumed obj.data is always a Mesh; non-mesh
objects (empties, lights, etc.) have obj.data = None,
causing an AttributeError on obj.data.edges.
- view3d_utils was used but never imported.

Add --format ids to the ifcquery.rst format description and a new
"Scripting with ifcedit" section showing composition examples. Add
the foreach subcommand to ifcedit.rst with usage examples.
Add ifcquery, ifcedit and ifcmcp to the README contents table, the
Sphinx docs toctree and introduction utilities table. Add new .rst
pages for each package documenting subcommands, installation, usage,
and parameter types. Fix plot and render CLI examples in ifcquery
README to use -o/--out-format flags. Update ifcmcp README to use the
installed ifcmcp command rather than python3 -m ifcmcp.

These three packages were added to src/ but lacked the Makefile needed
by common.mk to build distribution wheels, and the GitHub Actions
workflow to publish them to PyPI.
Adds make dist / make test / make qa targets and ci-*-pypi.yaml
workflows matching the pattern used by ifcpatch, ifcclash, etc.
IfcRelConnectsPathElements has an optional ConnectionGeometry attribute for
recording the geometric cut-plane between adjacent elements, but there was
no way to set it via the API.

assign_product creates IfcRelAssignsToProduct linking a structural member to
a physical building element. assign_to_building creates IfcRelServicesBuildings
linking a structural analysis model to a building. add_topology_representation
creates IfcTopologyRepresentation for structural elements, inferring the
representation type from the item class.

Both attributes are required by the IFC schema but were not settable via
the API function. Add physical_or_virtual and internal_or_external parameters
with "NOTDEFINED" defaults for backward compatibility. Update Bonsai boundary
panel to expose both fields in the editor.

Add --format ids to ifcquery to output step IDs suitable for piping into
ifcedit parameters. Add ifcedit foreach to apply an operation to every
element in a query result. Extend clash and relations output so --format ids
extracts all involved element IDs, enabling one-liners like clash detection
piped directly into render.

Enhances the performance of mouse intersection checks for wireframe objects.
Details:
- Calculated the intersection with the mouse in 2D pixels first.
- Converted objects to a BVH Tree to reduce the number of edges checked against the mouse position.
mcp is an optional dependency so that the embedded API (embedded.py) can
be used from Pyodide without pulling in pydantic-core and the rest of the
MCP protocol stack, which may not be available in all WASM environments.
Fix#7034
bpy.ops.bim.extend_to_underside doesn't exist - the correct operator
name is bim.extend_walls_to_underside. The AttributeError killed the
entire panel draw, hiding mirror, align, aggregation, and QTO buttons.

If a file had an IfcProjectedCRS without an IfcCoordinateOperation (or
vice versa), add_georeferencing would return early without creating the
missing entity. This caused edit_georeferencing to crash with IndexError.
Now detects the inconsistent state, cleans up, and recreates both.

ifcmcp is a new Model Context Protocol server that wraps ifcquery and ifcedit, holding an IFC model in memory across tool calls. It is the preferred way to interact with IFC models from AI assistants and MCP-compatible clients.
Setup:
claude mcp add --transport stdio ifc -- python3 -m ifcmcp
Session tools: ifc_load, ifc_save
Query tools: ifc_summary, ifc_tree, ifc_info, ifc_select, ifc_relations, ifc_clash, ifc_validate, ifc_schedule, ifc_cost, ifc_schema, ifc_contexts, ifc_materials, ifc_plot, ifc_render, ifc_shape, ifc_shape_list, ifc_shape_docs
Edit discovery: ifc_list, ifc_docs
Edit execution: ifc_edit, ifc_quantify
The model stays in memory between calls - ifc_edit does not auto-save; call ifc_save explicitly when done.
Depends on both ifcquery and ifcedit

ifcedit is a new command-line tool for executing ifcopenshell.api mutations from the shell. It wraps the entire API surface — any function callable via ifcopenshell.api can be invoked without writing Python.
Subcommands:
list [module] — list all API modules, or functions within a module
docs <module.function> — full documentation (params, types, descriptions)
run <file> <module.function> [--param value ...] — execute a mutation; overwrites input file by default, or use -o <output> to write elsewhere; --dry-run validates without executing
quantify list — list available QTO rules
quantify run <file> <rule> — run quantity take-off, writing IfcElementQuantity psets back to the file
Parameter coercion: entity references can be passed as step IDs (strings); lists, dicts, booleans, and None are handled automatically.
Usage:
python3 -m ifcedit run model.ifc root.remove_product --product 42
python3 -m ifcedit docs geometry.edit_object_placement

ifcquery is a new command-line tool for querying and inspecting IFC models. All output is JSON.
Subcommands:
summary — schema version, entity counts, project metadata
tree — full spatial hierarchy (Project → Site → Building → Storeys → Spaces → Elements)
info <id> — deep inspection of any entity by step ID (attributes, psets, placement matrix, type, material)
select <query> — filter elements using ifcopenshell selector syntax
relations <id> — relationships for an element; --traverse up walks to IfcProject
clash <id> — geometric intersection and clearance detection
validate — schema/constraint validation; --rules adds EXPRESS checks
schedule — work schedules with nested task trees
cost — cost schedules with nested cost item trees
schema <class> — IFC class documentation from the model's schema version
plot — SVG plan drawing
render — 3D geometry rendering
contexts — geometric representation contexts
materials — material assignments
Usage:
python3 -m ifcquery <file.ifc> <subcommand> [args]

Add tests for all four covering generation operators: flooring/ceiling
from walls and flooring/ceiling from cursor. Previously only flooring
from walls was tested.

The covering tool used bmesh as an intermediate and relied on
type.assign_type post-listeners (removed in 44a52863a) to generate
the IfcExtrudedAreaSolid body. With those listeners gone, coverings
had no body representation and assign_swept_area_outer_curve crashed.
Build covering representations from scratch using ShapeBuilder, reading
the extrusion depth from the type's IfcMaterialLayerSet. Also replace
bpy.ops.bim.assign_class with bonsai.core.root.assign_class using
should_add_representation=False, consistent with the space fix.
Refactored shared coordinate-conversion and extrusion-building logic
into get_2d_vertices_from_polygon and set_extrusion_representation_from_polygon,
used by both space and covering code paths. Removed all bmesh-dependent
dead code from the spatial tool.
