fix: Address PR #7589 review items - prefix rename, cleanup, copyright

- Rename all saikei.* operator idnames to civil.* per Bonsai convention - Rename SAIKEI_OT_*, SAIKEI_PT_*, SAIKEI_UL_* classes to CIVIL_* prefix - Rename SaikeiAlignmentProperties -> CivilAlignmentProperties - Rename saikei_* Blender object custom property keys to civil_* - Remove IOS-version-compat try/except fallback in _get_segment_vertices_in_model_units() now that Rick's segment_vertices() API accepts IfcAlignmentSegment directly - Remove try/except wrapper around get_alignment() - call directly - Add Michael Yoder copyright to __init__.py and operator.py - Fix misleading coordinate comment (IFC -> global easting/northing) - Document props.pis coordinate system (global E/N) in AlignmentPI and operator comments Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

-Linked IFC models (`bim.link_ifc`) had several gaps that made them hard to use as a
-"reference in other trades' models" workflow:
-
- One shared `.ifc.cache.blend` per IFC file meant the **same file could not be linked
-  twice with different selector queries** — both links showed whichever query was cached
-  first in-session, and whichever was cached last after reopening (Blender reuses one
-  library datablock per path).
- The selector query was not durably stored anywhere in the host IFC, so save → reopen
-  lost or cross-wired the filter; a scripted `bpy.ops.bim.reload_link()` also wiped it.
- Linked geometry got **flat diffuse-only materials** — external `.blend` styles
-  (`IfcExternallyDefinedSurfaceStyle`) and per-layer materials (layerset slicing) that
-  the normal import applies were ignored.
- Moving a linked model required an explicit enable-edit → move → save dance on the
-  active link only, with save/cancel buttons in the panel header.
- The Explore tool's highlight broke (GPU type errors), drew at the link's *original*
-  location when the link had been moved, and `bim.append_inspected_linked_element`
-  placed appended elements at the original location too.
-
-## Key facts established
-
- **Cache architecture**: `LoadLink.link_ifc` generates a Python script and runs a
-  background Blender subprocess that executes `bim.load_linked_project` and saves a
-  `.ifc.cache.blend`. The host session then *links* (not appends) the `IfcProject/...`
-  collection from that blend and instances it via an empty (the link "handle").
-  Georeferencing metadata lives in a sidecar `.cache.json`; extracted properties in
-  `.cache.sqlite` (whole file, query-independent — deliberately shared across queries).
- **Blender reuses an in-session library per path.** Loading the same blend path twice
-  yields the same library/collection. This is what broke multi-query linking with a
-  shared cache filename, and why per-query *filenames* (not cache invalidation) are the
-  fix.
- **Last-used operator properties** are reused on the next *interactive* invocation
-  (UI button), while scripted `bpy.ops` calls always start from defaults. LoadLink's
-  internal `self.query = link.query` fallback assignment was remembered by Blender and
-  leaked into the next button click (`operator_query='IfcWindow'` for the door link).
-  Any `is_property_set()`-based logic is corrupted the same way. Fix: `SKIP_SAVE` on
-  volatile props. **A GUI-only bug like this is invisible to scripted repro** — both
-  headless and windowed `--python` test runs passed while the manual flow failed.
- **`IfcDocumentReference`** per link: attribute index 1 (`Identification`) already
-  stores the link's 4×4 transformation (existing Bonsai convention). `Description`
-  (IFC4+; **absent in IFC2X3**) now stores the selector query. One
-  `IfcDocumentInformation` (Scope `LINKED_MODEL`) per file, one reference per link.
- **Geometry iterator materials**: `material.instance_id()` is the STEP id of the
-  `IfcSurfaceStyle` — or of an `IfcMaterial` when the item has a material but no style,
-  hence the `is_a("IfcSurfaceStyle")` guard when resolving external styles.
- **External styles**: `IfcExternallyDefinedSurfaceStyle.Location` (`.blend`, relative
-  paths resolve against the *linked* IFC, not the host) + `Identification` in
-  `data_block_type/name` form (e.g. `materials/Brick`), same convention as
-  `bim.activate_external_style`.
- **Chunk pipeline dedups materials by RGBA color** (`np.unique` on a color array), so
-  style identity must ride along as an extra column to survive — added only for styles
-  that actually resolve to an external material, so plain colored styles dedupe exactly
-  as before.
- **`slice_layerset_mesh` needs a local-space, per-element mesh** (bisect planes are in
-  object space), which the chunk path can't provide (world-space, many elements per
-  mesh) — hence routing multi-layer elements through the instanced path. Its
-  `dissolve_limit` produces **ngons**, which broke the Explore highlight's
-  triangles-from-`polygon.vertices` assumption downstream.
- **ID properties round-trip as `IDPropertyArray`**, not plain lists (verified in
-  4.5.7: empty list → flat `IDPropertyArray`; nested lists → list of `IDPropertyArray`
-  items), and `GPUIndexBuf` rejects them — selection geometry must be converted to
-  plain tuples on read.
- **`scene.ray_cast` returns the hit instance's world matrix** (link empty matrix
-  included). For instanced occurrence objects the object's own local matrix is *not*
-  identity, so resolving the instancing empty must compare against
-  `empty.matrix_world @ obj.matrix_world`, not the empty's matrix alone.
- **Link matrix math**: the handle empty's matrix is `inv(L) @ T @ G` (L = host local
-  matrix from georef props, T = stored transformation, G = linked model's global
-  matrix from the cache json). The world-space displacement of a moved link is
-  therefore `inv(L) @ T @ L` — no json read needed (`calculate_link_delta_matrix`).
- **Undo consistency of auto-saved moves**: Blender undo of a handle move fires another
-  depsgraph update, so the handler re-saves the reverted matrix — stored state stays
-  consistent without transactions (a handler can't open one).
-
-## Design
-
-### Per-query caches + query persistence (multi-linking)
-
-`tool.Project.get_link_cache_paths(filepath, query)` appends `.md5(query)[:8]` to the
-cache blend/json names; the empty query keeps the legacy un-suffixed names so existing
-caches stay valid. Every cache-path consumer goes through it — `link_ifc` build and
-invalidation, the subprocess json write, model-origin/georef indicator reads,
-`calculate_link_matrix`, `save_link_transformation`, and the per-link
-selectability/wireframe/visibility toggles (which match collections *by library
-filepath* and would otherwise affect every link of the file at once).
-
-The query persists on each link's `IfcDocumentReference.Description` (written by
-`LinkIfc` and `ReloadLink`); `load_linked_models_from_ifc` restores from it, with a
-legacy-JSON fallback that only applies when the file has a **single** link (with
-several links the shared JSON can't say which link it belonged to). IFC2X3 hosts have
-no `Description` — custom queries are not restorable there (accepted).
-
-`LoadLink`/`ReloadLink` volatile properties are `SKIP_SAVE` (see key facts). Cache
-clearing tolerates a missing blend (a reload with a brand-new query points at a
-not-yet-existing filename).
-
-### Include/Exclude filter pair
-
-The selector grammar's only cross-group combiner is `+` (union) and the `parent`
-facet cannot express "not under X" (its `!=`/regex paths also match by GlobalId, so
-negation removes everything with any parent), which makes set differences like
-"group members minus the slabs under aggregate X" structurally inexpressible in one
-query string. Links therefore carry an **Exclude** query beside the include —
-mirroring `EPset_Drawing`'s Include/Exclude pattern: final set = include (or the
-default set when empty) − exclude, applied in `LoadLinkedProject` and per link in
-`create_drawing`.
-
- **Cache key**: `get_link_cache_paths` hashes `md5(query + "\0" + exclude)` when an
-  exclude exists; include-only filters keep the pre-exclude `md5(query)` so existing
-  caches stay valid; empty filter keeps legacy un-suffixed names. Keying on query
-  alone would let same-include/different-exclude links silently serve each other's
-  geometry.
- **Persistence**: `encode_link_filter`/`decode_link_filter` — a plain include is
-  stored in `Description` as-is (backwards compatible); an exclude, a `loaded`
-  state or a custom display name promotes the value to
-  `{"include": …, "exclude": …, "loaded": …, "name": …}` JSON. Decode treats
-  non-JSON as a legacy include string. The display name (`Link.display_name`,
-  double-click the list row to rename; file path shows as placeholder while
-  unset) exists to tell apart several links of the same file.
- Exclude applies on top of the **default** element set too, so
-  "everything except X" needs no explicit include.
- UI labels are **Include**/**Exclude** (matching the drawing pattern), but the
-  property identifier stays `query` for script (`bpy.ops.bim.link_ifc(query=…)`)
-  and persistence compatibility.
- Verified headless: `query=""`/`exclude="IfcDoor"` loads only the window;
-  same file with a different filter gets its own cache; both filters survive
-  save → reopen → reload.
-
-### Auto-load on open
-
-Links that were **loaded and visible** at IFC save time auto-load when the project
-is reopened. `ExportIFC` calls `tool.Project.update_linked_models_state()`, which
-rewrites each reference's `Description` with a `loaded` flag
-(`is_loaded and not is_hidden`); `load_linked_models_from_ifc` replays flagged
-links via `load_link` after restoring the list (missing files warn and skip so
-they can't break project open). The flag extends the same JSON blob as the
-exclude — plain legacy strings decode as no-autoload. Trade-off: project open
-pays the link-load cost up front (fast on cache hit; a missing cache rebuilds in
-a background Blender, same as clicking Load). Verified headless: loaded+visible
-auto-loads; unloaded and loaded-but-hidden links stay unloaded.
-
-### Long-term serialization target: STEP Part 21 Edition 3
-
-STEP p21e3 defines the standards-track version of this feature's persistence:
-`ANCHOR`/`REFERENCE` sections (clauses 9–10) let one file import entities from
-another via URI + fragment, and **anchor tags** (`{tagname: value}`) are the
-designated slot for out-of-schema metadata — a cleaner home than the
-`Description` JSON blob (see the review-round discussion). ifcopenshell does not
-implement these sections yet ([#668](https://github.com/IfcOpenShell/IfcOpenShell/issues/668),
-open, unassigned); if it ever does, the migration path is: link →
-`REFERENCE` to the linked file's project anchor, filter/transform/loaded
-metadata → anchor tags. Keeping the blob behind
-`encode_link_filter`/`decode_link_filter` makes that a two-function change.
-
-Two p21e3 design points this branch already conforms to:
-
- **Identity**: p21e3 distinguishes volatile file-scoped entity numbers
-  (`#100` fragments) from durable anchors/UUIDs — the same lesson behind our
-  STEP-id collision fixes (GUID-based matching, `element.file` guards). Raw
-  STEP ids must never cross a file boundary; IFC GlobalIds map 1:1 onto
-  p21e3 UUID anchors.
- **Transport** (clause A.4): exchange structures plus referenced resources
-  can ship as one ZIP archive with references resolving inside it. Our posix,
-  optionally relative `Location`s resolved via `resolve_uri` are exactly the
-  invariants a future "package project with links" export would need.
-
-Even full p21e3 support would not cover per-link transforms, filters, or load
-state — a `REFERENCE` imports entities, it does not place a model — so the
-app-level metadata remains; only its container would change.
-
-### External styles + layerset slicing in the linked loader
-
-`LoadLinkedProject.get_external_material(style_id)` resolves a style id → appended
-Blender material from the external `.blend`, cached two ways (per style id; per
-appended data-block, so styles sharing one material don't append duplicates). Appended
-materials get their stale `ifc_definition_id` cleared (the source `.blend` may have
-been authored in a Bonsai session; the id would be misread in the linked file *and*
-in the host once the cache links in). Applied in both loading paths — instanced
-occurrences directly, chunks via the style-id column.
-
-Multi-layer elements (`IfcMaterialLayerSetUsage`, >1 layer) route through the
-instanced path and get `slice_layerset_mesh`, which gained a pluggable
-`style_to_material` resolver (defaults to the old `tool.Ifc.get_object` for the normal
-import) — the linked resolver prefers the external material, falling back to a flat
-diffuse from the style's shading colour. Also fixed there: newly appended layer
-materials are registered in the dedup dict (two layers sharing one style used to
-append it twice).
-
-Trade-off: layered walls become individual instanced objects instead of chunk members;
-meshes shared between elements (same geometry id) bake the slice from the first
-element's layerset usage — same behaviour as the normal importer.
-
-### Reload Link dialog
-
-`bim.reload_link` now exposes File Path (+ browse button), Use Relative Path
-(defaulting to the stored path form), Use Cache (default off = old always-rebuild
-behaviour), the False Origin Mode project props, and Query. A file browser can't open
-from inside a props dialog, so the browse button runs `bim.select_link_filepath`
-(fileselect) which *reopens* the reload dialog with the chosen path, carrying the
-in-progress dialog state through the round trip (op props are baked at draw time).
-Path changes update `link.name`/`filepath` and, with a host IFC, the reference
-`Location` + document name — which is why `ReloadLink` became a `tool.Ifc.Operator`.
-Script calls without arguments preserve all stored link values via `is_property_set`.
-
-`bim.reload_all_links` (refresh button beside Link IFC in the panel header) reloads
-every *loaded* link via argument-less `reload_link` calls — each link's stored
-path/query/exclude replay and its cache rebuilds from disk. Unloaded links are left
-alone. Deliberately expensive: one background cache rebuild per link.
-
-### Per-row lock toggle + auto-saved transforms
-
-Link editing moved from the panel header into each list row as a lock/unlock icon:
-unlock (`bim.enable_editing_link`) frees the handle; **any movement is persisted
-immediately** by a `depsgraph_update_post` handler (lazy — ticks without transform
-updates cost ~nothing); lock (`bim.disable_editing_link`) saves and locks.
-`bim.edit_link` and the explicit save step are **removed**; cancel/restore semantics
-no longer exist (undo or move it back). The save math lives in
-`tool.Project.save_link_transformation`. Enable/disable take a `link_index`
-(default −1 = active link) so several links can be edited at once and script calls
-stay compatible.
-
-### Explore tool + append fixes for moved links
-
- Highlight triangles come from `mesh.calc_loop_triangles()` filtered to the queried
-  element's polygon range (ngon-safe); edges keep `polygon.edge_keys` (no diagonals).
- `get_selected_geometry` converts the ID-prop round trip to plain tuples (GPU
-  rejects `IDPropertyArray`); TRIS drawing gated on its own data.
- `QueryLinkedElement` passes the ray-cast instance matrix through;
-  `find_obj_root` compares it against `empty @ obj_local` and falls back to the
-  collection's only instance when no matrix is available (select-by-GUID flow).
- `bim.append_inspected_linked_element` pre-multiplies the imported object's matrix by
-  `calculate_link_delta_matrix(link)`, matching the link by the queried instance's
-  root empty first (filepath alone is ambiguous with several links per file). The
-  element's IFC placement syncs to the moved location on save — intended.
-
-### Drawings (`create_drawing`) — moved links and per-link queries
-
- The linework serializer opened linked IFCs raw, so a moved link's elements were
-  drawn at their *original* coordinates (usually outside the drawing extents —
-  "linked objects disappear from prints after moving the link").
- The stored link transformation is already the **model-space** delta (that is how
-  `save_link_transformation` derives it), which is exactly the space the serializer
-  works in — so it can be baked straight into the geometry iterator via the existing
-  `model-offset`/`model-rotation` settings. The mapping composes
-  `Trans(model-offset) @ Rot(model-rotation)` (see `mapping.cpp`), matching the
-  `Trans(t) @ Rot(R)` decomposition of the rigid link matrix; `model-rotation` is a
-  quaternion passed as `(x, y, z, w)`. The pre-existing 2mm plan-view Z-offset simply
-  adds onto the translation (translations commute).
- The serialization loop previously collected files in a dict keyed by filepath, which
-  **collapsed same-file links into one pass** (one transform — the last link's — and
-  no query awareness): with two links of one file, only one showed in the drawing.
-  It now iterates one entry per link (`(path, file, transform, query)` tuples), and
-  intersects each link's drawing elements with
-  `ifcopenshell.util.selector.filter_elements(ifc, link.query)` so the drawing shows
-  what that link actually displays in the viewport.
- `tool.Project.get_link_transformation_matrix(link)` is the shared accessor for the
-  stored 4×4 (None when identity/absent).
- Verified headless with the window/door kit: moved window offset in the SVG by
-  exactly 5m × scale; unmoved door at its native position; both links present.
-
-### Drawings — `.cut` styling for linked models (BISECT cut mode)
-
- The default **BISECT** cut mode deletes the OpenCASCADE serializer's cut linework
-  (`remove_cut_linework`) and regenerates cuts by bisecting **Blender mesh objects**
-  (`generate_bisect_linework` over `context.visible_objects`). Linked models are
-  instanced collections with no mesh objects, so their cuts were deleted and never
-  regenerated — linked elements only ever appeared as `projection`, and the `.cut`
-  CSS rule never applied to them. Long-standing gap, unrelated to moved links
-  (A/B-tested against pre-branch code: identical).
- Fix: `remove_cut_linework` only removes cut groups whose guid resolves in the
-  **host** file — linked elements keep the serializer's cut geometry, which the
-  merge step then classes as `cut`.
- **Cross-file STEP-id collision**: `tool.Ifc.get_object(linked_entity)` resolves the
-  entity's STEP id against the *host* session's id map and can return an arbitrary
-  host object (in the test project: the drawing camera, crashing
-  `generate_material_layers` with "expected 'Mesh' found 'Camera'"). Guarded via
-  `element.file is tool.Ifc.get()` in `generate_material_layers` and the merge step.
- **Paint order**: the projection-under-cut convention was enforced only in
-  OPENCASCADE mode (`move_projection_to_bottom`); BISECT appends its own cut paths
-  last so it never needed it — but the retained serializer cuts of linked models are
-  emitted *before* the projections. BISECT now runs the same pass; `BringToFront`
-  (`move_elements_to_top`) still gets the final say.
- Known limitation: linked cut paths are raw serializer output — they skip the
-  shapely path-closing/merging and the material-layer hatching pass (both need host
-  Blender objects). Stroke + fill from `.cut` CSS apply; layered hatching inside
-  linked cuts is a candidate follow-up.
- Debugging note: merged cut groups carry member guids as CSS *classes*, not as the
-  `ifcopenshell:guid` attribute — inspect both when checking cut output.
-
-## Deferred refactors (deliberate)
-
- **Upstream `exclude=` on `filter_elements`** — the include−exclude set difference
-  is hand-rolled twice (links, drawings) because the selector grammar has no
-  difference operator and `parent` negation is broken by design (its `!=`/regex
-  paths also match GlobalIds, so negation strips everything that has a parent).
-  The right home is an `exclude=` parameter on
-  `ifcopenshell.util.selector.filter_elements`, documented in
-  `selector_syntax.rst` together with the `parent`-negation limitation. Deferred
-  to a separate ifcopenshell-python PR (different review audience; would widen
-  this PR mid-review). Once it lands, both Bonsai call sites collapse.
- **Core/tool ceremony skipped** — the new `tool.Project` methods have no
-  `core/tool.py` interface declarations and no `bonsai/core` orchestration
-  functions, matching the pre-existing linked-model code (which bypasses the
-  core layer wholesale; `LoadLinkedProject` is flagged "prototyping" upstream).
-  Interfaces nobody calls through wouldn't add testability — the pure helpers
-  (`encode_link_filter`/`decode_link_filter`, `get_link_cache_paths`) are
-  covered directly in `test/tool/test_project.py` instead. Revisit if the
-  linked-model subsystem is ever promoted out of prototype status.
-
-## Review round 1 (PR #8242, falken10vdl) — decisions
-
- **Path-form mismatch → duplicate documents (confirmed bug, fixed).**
-  `get_linked_models_documents()` keyed documents by the *stored* `Location`, so
-  linking the same file first relative then absolute (or vice versa) created a second
-  `IfcDocumentInformation`. Both sides of the lookup now normalize through
-  `tool.Ifc.resolve_uri()` before matching.
- **`Description` for the query — kept.** It is implementation metadata in an IFC
-  attribute, but consistent with the existing convention on these same references
-  (`Identification` stores the 4×4 transformation, a bigger stretch). References are
-  Bonsai-managed (`Scope="LINKED_MODEL"`), so user-description collisions are unlikely.
-  A cleaner consolidated convention (query + transform + options in one serialized
-  attribute) is a candidate follow-up, deliberately out of scope here.
- **`md5(query)[:8]` — kept.** 32 bits ≈ birthday collision at ~65k distinct queries
-  *per file*; and a collision is not silent: the cache JSON stores the full query and
-  `should_clear_cache()` compares it, so a colliding cache is detected and rebuilt
-  (self-healing).
- **Depsgraph autosave vs save-on-lock — autosave kept.** Save-on-lock alone loses the
-  "what you see is what's saved" guarantee (move + save project without locking =
-  silently dropped move) and loses undo tracking (undo fires a depsgraph update that
-  re-saves the reverted transform). The handler early-outs when no links exist and only
-  works on ticks containing an object-transform update while a link is unlocked.
-
-## Status — implemented (verified in Blender, incl. headless + GUI repro runs)
-
-Six commits on `Linked_File_Features`:
-
- `0096c0f6a2` reload_link without a query preserves the stored one.
- `40db55e52d` external styles + layerset slicing for linked models
-  (`project/operator.py`, `tool/loader.py`).
- `d210d4c814` full Reload Link dialog + `bim.select_link_filepath`.
- `3dc161f0f2` per-row lock toggle, auto-save handler, `edit_link` removed
-  (`project/operator.py`, `project/ui.py`, `project/__init__.py`, `tool/project.py`).
- `0571d22855` Explore highlight (ngons, IDPropertyArray), moved-link highlight,
-  append placement (`tool/project.py`, `project/operator.py`, `project/decorator.py`).
- `c14592ec0a` per-query caches, Description persistence, SKIP_SAVE.
-
-Plus:
-
- `ee43ed5526` review-round path normalization in `get_linked_models_documents` /
-  `LinkIfc` (see Review round 1).
- `1669cbcd43` drawing support for moved links and per-link queries in
-  `create_drawing` (`drawing/operator.py`, `tool/project.py`).
- `.cut` styling for linked models in BISECT cut mode + STEP-id collision guards +
-  paint order (`drawing/operator.py`) — committed together with this note update.
-
-End-to-end verified with a two-links-one-file kit (window/door, distinct queries):
-correct visuals on load, after save → reopen → reload, in both headless and windowed
-Blender.
-
-## Things to test / verify
-
- **IFC2X3 host**: `Description` doesn't exist — link queries silently not restored on
-  reopen (legacy fallback only for single-link files). Acceptable? Warn?
- **Relative-path links** (`use_relative_path`) through the whole cycle: cache paths,
-  reference `Location`, reload path change, query restore. The duplicate-document case
-  (same file linked relative then absolute) is fixed — verify one document with two
-  references via `IfcDocumentInformation.HasDocumentReferences`.
- Same file linked twice, **both moved differently**: Explore highlight and append
-  placement per instance (root-empty matching), per-link visibility toggles.
- External styles with **image textures**: paths relative to the style's source
-  `.blend` may not resolve from the cache blend's location (shared limitation with the
-  normal import path).
- Stale cache orphans: per-query filenames accumulate one blend+json pair per distinct
-  query next to the IFC; nothing auto-deletes them. Cleanup on unlink? Document?
- Mid-drag auto-save writes the IFC reference outside Bonsai's transaction system —
-  confirm no undo-stack weirdness in longer editing sessions.
- Layerset slicing on meshes shared by elements with *different* usages (offset/sense)
-  bakes the first element's slice — same as normal import, but worth a look with types.
- `bim.select_link_filepath` round trip when the reload dialog was opened for a
-  non-active link, and dialog-state carry-over after editing the query *then* browsing.
- **Drawing SVG guid cache vs moved links**: `create_drawing` skips elements whose
-  guids already exist in the drawing's SVG (`cached_linework`, invalidated only for
-  *edited host objects*). Moving a link does not invalidate its elements, so a
-  regenerated drawing keeps their old positions until the SVG is deleted. Candidate
-  fix: subtract a moved link's guids from `cached_linework` (compare stored transform
-  against the one recorded at last generation).
- Same element appearing in two links of one file (overlapping queries) serializes
-  twice with different transforms; the SVG guid cache keeps whichever came first on
-  regeneration. Degenerate case — probably fine to ignore, but note it.

-The goals of the Open Font License (OFL) are to stimulate worldwide
-development of collaborative font projects, to support the font creation
-efforts of academic and linguistic communities, and to provide a free and
-open framework in which fonts may be shared and improved in partnership
-with others.
-
-The OFL allows the licensed fonts to be used, studied, modified and
-redistributed freely as long as they are not sold by themselves. The
-fonts, including any derivative works, can be bundled, embedded, 
-redistributed and/or sold with any software provided that any reserved
-names are not used by derivative works. The fonts and derivatives,
-however, cannot be released under any other type of license. The
-requirement for fonts to remain under this license does not apply
-to any document created using the fonts or their derivatives.

DesertSpringsCivil	a3038528bb	Add PI Edit Mode for moving alignment points with G key Implements the ability to edit alignment PI (Point of Intersection) positions after creation using Blender's standard transform tools: - Back-calculate PI positions from existing IFC alignment segments - Create temporary EMPTY objects at PI locations for editing - Visual feedback via PIEditDecorator (yellow tangent lines, HUD) - Modal operator handles G key movement, Enter to apply, Escape to cancel - Regenerates alignment with new PI positions on apply - Handles edge cases: single-segment, tangent-only, undo during edit Architecture follows Bonsai patterns: - Core layer: Business logic orchestration (enter/exit_pi_edit_mode) - Tool layer: Math, IFC, and Blender implementations - UI layer: Modal operator with PASS_THROUGH for standard transforms Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-02 20:26:41 -07:00

DesertSpringsCivil	46da629c8b	Create selectable curve geometry for alignment segments Replace segment empty objects with actual curve geometry so that selecting a segment in the Outliner highlights the corresponding line/curve in the viewport. Changes: - Add get_segment_vertices() using IfcOpenShell's evaluate_segment() to sample points along individual segments via the geometry engine - Replace _create_segment_empty with _create_segment_curve that creates Blender CURVE objects with actual geometry - Remove single HorizontalCurve in favor of per-segment curves - Supports all segment types (LINE, CIRCULARARC, CLOTHOID, spirals, etc.) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-02 16:41:04 -07:00
DesertSpringsCivil	fd85b29777	Hide zero-length terminator segments from UI and suppress empty alignment warnings Zero-length segments are required by IFC to mark alignment ends but should be invisible to users. This change: - Adds helper methods to detect zero-length and empty layouts - Silently skips geometry generation for empty alignments (no error messages) - Excludes zero-length segments from Outliner display - Uses separate visible segment counter for consistent naming Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-02 15:34:07 -07:00
DesertSpringsCivil	95952d03f8	Fix PI picker viewport coordinate calculation and add georeference support - Fix modal operator to use absolute mouse coordinates converted to 3D viewport region space, instead of event.mouse_region_x/y which are relative to whichever region received the event - Store 3D viewport area, region, and region_data references in invoke() for consistent raycasting throughout modal operation - Add coordinate transformation methods (blender_to_ifc_coordinates and ifc_to_blender_coordinates) for projects with geospatial Blender offsets - Transform alignment curve vertices from IFC global to Blender local coordinates when has_blender_offset is enabled - Add try/except for piecewise-step-size geometry setting in util.py Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-02 10:19:02 -07:00
DesertSpringsCivil	5ad40612fb	Remove Import CSV button and PI Details panel from alignment UI Simplifies the Horizontal Alignment panel by removing the Import Alignment CSV button and the PI Details submenu that displayed when selecting rows in the PI Editor list.

DesertSpringsCivil	6294c35a11	Handle RuntimeError in alignment geometry generation Add RuntimeError handling for IfcOpenShell versions that don't support the piecewise-step-type setting in geometry generation. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-01 18:40:49 -07:00
DesertSpringsCivil	de2a7c9527	Add CIVIL tab to Bonsai Properties sidebar for alignment tools - Add new CIVIL tab (4th position) with CURVE_DATA icon - Create BIM_PT_tab_horizontal_alignment panel container - Move alignment UI from N-panel to Properties sidebar - Remove old "Saikei Civil" N-panel tab Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-01 18:39:38 -07:00
DesertSpringsCivil	a37de44a24	Fix dev_environment.py Windows compatibility for symlink handling Git checkout with glob patterns (*.ifc) doesn't work on Windows. This change: - Expands glob via git ls-files and checks out files individually - Skips symlink recreation if they already exist and are valid - Refreshes git index before checkout to recognize deleted files Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-31 14:43:13 -07:00
DesertSpringsCivil	c0b7256832	Use IfcOpenShell geometry engine for alignment visualization Replace manual per-segment geometry creation with IfcOpenShell's built-in generate_vertices() utility. This provides automatic support for all curve types (CLOTHOID, spirals, etc.) and removes ~75 lines of manual geometry code. Changes: - Add create_curve_from_representation() using IfcOpenShell geometry engine - Add _create_segment_empty() for segment selection without geometry - Update create_objects_for_layout_segments() to use new methods - Delete manual geometry methods: create_object_for_segment(), _create_line_segment(), _create_arc_segment() Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-31 13:35:20 -07:00
DesertSpringsCivil	42db172827	Clean up unused imports in alignment operator module Removed leftover imports from sequence module template: - isodate, dateutil, calendar, datetime - bonsai.bim.module.sequence.helper - ifcopenshell.util.sequence, ifcopenshell.geom, ifcopenshell.util.selector - Duplicate imports (os, json, ImportHelper, ifcopenshell.api.alignment) These unused imports were causing silent module registration failures.
