-Docker build environment
-========================
-
-This is a small utility to make it easy to compile a perfect `_ifcopenshell_wrapper.cpython-*-x86_64-linux-gnu.so`
-files.
-
-The reason for this tool is that I was trying to follow the web page directions, and my build was behaving differently
-to the release builds. Eventually I concluded that the differences between toolchains on the RHEL based rocky9 image
-and Ubuntu were just too great. Getting the build setup was already a lot of trial and error, so I thought I'd spend
-more time trying to reuse the github actions that perform the build, using a utility called `act`. I learnt a lot, in
-particular how much time, energy, and bandwidth Github waste. I also realised I was most of the way to a regular docker
-setup anyway, so I might as well just do that. So I've deconstructed all the github action steps, and turned it into
-a local docker build environment that uses the exact same base, tools, libraries, and build command/flags etc.
-
-Right now a Github action will:
- launch the rocky9 base
- upgrade all the packages
- install a bunch of extra tools
- do a recursive checkout of your repo
- checkout the build repository
- unpack dependencies
- run the build script, making all python versions (5? right now I think)
- create the .zip release files
-
-And it does _all_ of that _every_ time. This is not a fault of the action writers - it's just how Github seems to work.
-
-These dockers tools do the following differently, and it's actually a bit more powerful too:
- build the base image once.
- update the packages once.
- install the extra tools once.
- the repository is the one on your host, that gets bind mounted in the container as the working directory.
- by adding an environment variable to .env, restricts to compiling for just a single python version.
- when the build is finished the created files are right there under your local repositry (but not added to git) for
-  ease of access
- each repository can have it's own build environment container.
- the image is shared between those environments.
- the containers share the ccache, so additional envs should get a helping hand.
- it has a simple set of user friendly commands to drive it all.
-
-For example:
-``` bash
-# To see the commands (a superset of docker compose commands)
-./ifcos_env
-
-# Enable autocomplete of commands
-source .ifcos_env
-
-# First time commands
-./ifcos_env create
-./ifcos_env up
-./ifcos_env build
-
-# install and test library
-# find an issue
-# edit code
-./ifcos_env build
-
-# and so on. When done stop and optionally delete the container
-./ifcos_env stop
-./ifcos_env remove
-```
-
-To limit the build to one python version just add
-``` bash
-PY_TGT=py-311
-```
-or whichever version your Blender requires.
-
-You might see UNIQUE_ID in the .env file too. This keeps containers for separate folders, separate.
-
-System requirements
-1. Linux-x64 only at this time.
-2. Docker and docker-compose need to be installed.
-3. Have a good amount of disk space. (image is in /var (typically the root partition) and will be about 1.7 GB)
-4. The build action will create about 10GB in your repository folder. Make sure this partition is spacious
-   particularly if you intent on having multiple clones building.
-5. ... I think that covers most of it.

-name: ifcopenshell-docker-build
-description: >-
-  Build a real ifcopenshell_wrapper (.so + .py) and IfcConvert locally via
-  the docker/ifcos_env toolchain, then wire them into a checkout for
-  running C++-dependent parts of the test suite (geometry, the SWIG
-  wrapper stub, the C++ parser). Use whenever a task needs to compile
-  IfcOpenShell's C++ core rather than just read/patch source - e.g.
-  reproducing or fixing a bug in src/ifcgeom, src/ifcparse, src/ifcwrap,
-  or validating util/scripts/validate_stub.py against the actual
-  generated wrapper.
---
-
-# Building IfcOpenShell locally with docker/ifcos_env
-
-`docker/` mirrors the project's GitHub Actions build environment locally,
-in a persistent, non-root container with ccache so repeat builds are fast.
-See `docker/README.md` for the design rationale. Pure-Python changes don't
-need any of this - only reach for it when you need a real compiled
-`_ifcopenshell_wrapper*.so` or `IfcConvert` binary.
-
-## Placement
-
-This `docker/` folder must live as a direct child of the repo root you want
-to build (sibling of `src/`, `cmake/`, etc.) - `compose.yaml` and
-`ifcos_env` resolve the repo via `../` relative to wherever `docker/`
-itself sits, and bind-mount it into the container. If you're setting this
-up in a fresh clone, copy the whole `docker/` directory there first.
-
-## Setup
-
-```bash
-cd docker
-./ifcos_env create   # build the image (shared by name across all your clones/checkouts, so usually instant after the first time anywhere)
-./ifcos_env up        # create + start the container, clone/unpack the third-party dependency cache (~10GB, one-time per container)
-./ifcos_env build     # full build: all deps + IfcParse + IfcGeom + IfcConvert + the Python wrapper, for one Python version
-```
-
-`PY_TGT` and `UNIQUE_ID` live in `docker/.env` - `PY_TGT` (e.g. `py-311`)
-restricts the build to one Python version instead of building five;
-`UNIQUE_ID` is a hash of the folder path, recalculated on every `up`, so
-each checkout gets its own container/volumes automatically.
-
-A full first build takes ~1.5 hours (mostly compiling IfcOpenShell's own
-C++, not the cached third-party deps). After that, ccache makes incremental
-rebuilds of a couple of touched `.cpp` files **under a minute**.
-
-## Container lifecycle
-
-The container is long-lived (`sleep infinity`) so exec'd commands and
-ccache state persist between builds. Commands map directly onto Docker
-Compose's own container-vs-image distinction:
-
-```bash
-./ifcos_env up         # create the container if it doesn't exist, then start it (runs ready_repo too)
-./ifcos_env stop       # stop the container, keep it around
-./ifcos_env start      # start it back up (same container, same filesystem layer)
-./ifcos_env restart    # stop, then start
-./ifcos_env down       # remove the container (and its network) entirely
-./ifcos_env recreate   # down, then up - a fresh container
-```
-
-Named volumes (`ccache`) and the bind-mounted repo/`build/` are unaffected
-by `down`/`recreate` - only the container itself goes away, and `up`
-recreates it from the image.
-
-## Fast iteration
-
-Pass a target to `build` to skip the parts you don't need:
-
-```bash
-./ifcos_env build IfcConvert           # only the executables (IfcConvert, IfcGeomServer) - skips the Python wrapper entirely
-./ifcos_env build IfcOpenShell-Python  # only the SWIG Python wrapper - skips executables entirely
-./ifcos_env build                      # no target = everything (needed the first time, or after touching shared headers)
-```
-
-Use this to keep the edit -> rebuild -> test loop fast when debugging: if
-you're only touching `src/ifcgeom/`, build `IfcConvert`; if you're only
-exercising the Python API, build `IfcOpenShell-Python`.
-
-## Where the artifacts land
-
-Build output goes to `<repo_root>/build/Linux/x86_64/install/` on the host
-(bind-mounted, not just inside the container), owned by you (see
-"Container user" below):
-
- `ifcopenshell/bin/IfcConvert` - the CLI binary
- `python-<version>/lib/python<X.Y>/site-packages/ifcopenshell/_ifcopenshell_wrapper*.so`
-  and `ifcopenshell_wrapper.py` - the compiled wrapper + its generated
-  Python glue
-
-## Testing against a checkout (automated / AI-driven)
-
-`_ifcopenshell_wrapper*.so` and `ifcopenshell_wrapper.py` are already
-gitignored under `src/ifcopenshell-python/ifcopenshell/`, which is exactly
-where a normal in-tree build would put them - copy the two files there:
-
-```bash
-SRC=build/Linux/x86_64/install/python-3.11.8/lib/python3.11/site-packages/ifcopenshell
-cp "$SRC/_ifcopenshell_wrapper.cpython-311-x86_64-linux-gnu.so" src/ifcopenshell-python/ifcopenshell/
-cp "$SRC/ifcopenshell_wrapper.py" src/ifcopenshell-python/ifcopenshell/
-```
-
-Then, to run the test suite against it:
-
-```bash
-export PATH="$PWD/build/Linux/x86_64/install/ifcopenshell/bin:$PATH"   # for IfcConvert-dependent tests
-cd src/ifcopenshell-python/test
-PYTHONPATH="$PWD/.." python3.11 -m pytest -p no:pytest-blender .
-```
-
-(`-p no:pytest-blender` avoids the pytest-blender plugin trying to find a
-`blender` executable and failing collection entirely, even for non-Blender
-tests.) You'll need the matching Python version's `pip install`s too
-(numpy, shapely, isodate, lark, tabulate, pytest, ... - whatever the
-modules under test import) since this is a bare interpreter, not the
-project's pixi env.
-
-**This is the pattern to use for automated or AI-driven verification.**
-Don't use `try` (below) for that - it overwrites files in a real, live
-Blender installation, which isn't something an automated/AI workflow
-should ever do without the human explicitly asking for it in the moment.
-
-## Testing in Blender itself (human only)
-
-`try` copies the built wrapper straight into your actual Blender/Bonsai
-extension install, for manual in-Blender testing:
-
-```bash
-./ifcos_env try
-```
-
-It reads `BLENDER_USER_RESOURCE` from `.env` - set this to wherever
-Blender's user resource folder for the Bonsai extension actually lives on
-your system, which depends on your own Blender setup:
-
-```bash
-# in docker/.env
-BLENDER_USER_RESOURCE=~/.config/blender/bonsai/
-```
-
-`try` figures out the built Python version from `build/.../install/`
-(disambiguating with `PY_TGT` if more than one version was built) and
-copies the wrapper to
-`$BLENDER_USER_RESOURCE/extensions/.local/lib/python<X.Y>/site-packages/ifcopenshell/`.
-
-## Container user
-
-The image runs as a non-root `builder` user, UID/GID matching your host
-account (passed as `--build-arg` by `create` from `id -u`/`id -g`, so it
-adjusts automatically - no manual flag needed even if you're not 1000:1000).
-Files the build creates under the bind mount come out owned by you, not
-root. Passwordless `sudo` is available inside the container (e.g. via
-`attach`) for the rare case you need root for something ad hoc.
-
-If you're picking up an existing checkout that was previously built with
-an older, root-based image, you may hit `Permission denied` the first time
-you run `up`/`build` under the new image - `build/`, `.git/modules/`, the
-`ccache` volume, `output/`, and `build.log` can all be left root-owned from
-before. Fix it once via the container's own root (no host `sudo` needed):
-
-```bash
-docker exec -u root -w /__w/IfcOpenShell/IfcOpenShell <container-name> \
-    chown -R "$(id -u)":"$(id -g)" .git/modules build output build.log /ccache
-```
-
-(`<container-name>` is `ifcopenshell-<UNIQUE_ID>` - see `docker ps -a`.)
-
-## Other things worth knowing
-
- **Linux x64 only.** `compose.yaml` pins `platform: linux/amd64`; on an
-  ARM host (e.g. Apple Silicon) this build isn't available.
- **The final "Package .zip archives" step of `build()` has a pre-existing
-  bash syntax error**, unrelated to compilation - the actual build already
-  succeeded by that point (look for `Built IfcOpenShell...` in the output),
-  so this is safe to ignore if you only need the raw artifacts under
-  `build/.../install/`, not packaged release zips.
- **`test_mmaped_stream` and similar `USE_MMAP`-dependent tests will fail**
-  against this build - `nix/build-all.py` is invoked with `USE_MMAP=OFF`
-  here. Not a bug in your code if you see it fail.
- Only the bind-mounted `<repo>/build` lives on the host filesystem your
-  repo is checked out on. Anything the container writes *outside* that
-  mount lives in the container's own writable layer under Docker's data
-  root (commonly `/var/lib/docker`, i.e. usually your root partition) -
-  keep an eye on `df -h /` if you're running several of these containers
-  at once.

DesertSpringsCivil	4043037484	style: Apply Black formatting to root/operator.py Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-13 10:00:35 -06:00
DesertSpringsCivil	eb1e79ea5c	fix: Route IfcAlignment creation through align_api.create() Addresses Rick Brice's PR review feedback on #7785. Root cause: the AddElement dialog was manually stitching together IfcAlignment layout containers and calling create_representation(), bypassing the validated construction sequence in align_api.create(). This left IfcGradientCurve.BaseCurve potentially None and skipped zero-length segment and stationing referent setup. Changes: - root/operator.py: alignment templates now call align_api.create() directly (HORIZONTAL, GRADIENT, CANT) or _create_polyline_representation (POLYLINE_2D/3D), then manually link the result to the Blender object via tool.Ifc.link + tool.Collector.assign. The old generic core.assign_class path is retained for all non-alignment templates unchanged. - tool/alignment.py: remove create_representation_structure() — superseded by the operator changes above. - create_representation.py: revert the if layout_nest: guard; with align_api.create() as the entry point the zero-length segment always exists before create_representation is called. - add_zero_length_segment.py: revert the BaseCurve None guard; the root cause (gradient curve created without a base curve) no longer occurs. - alignment/operator.py: guard _create_geometric_representation call so it only runs when no curve representation exists yet; auto-invoke create_alignment_by_pi after PI picker finishes if >=2 PIs are defined. - util/file.py: fix StopIteration on short IFC template files (next(ifc_file) → next(ifc_file, None) with break).

DesertSpringsCivil	d2ee4f2f97	fix: Correct vertical/cant segment handling in alignment API Two bugs prevented IfcAlignmentVertical segments from being added when a geometric representation exists. Bug 1 — _add_segment_to_curve.py: Removed an unconditional `if not curve.is_a("IfcCompositeCurve")` guard that was left over from when the function only supported horizontal segments. The preceding if/elif/elif chain already validates the correct curve type for each segment type; the redundant check always raised TypeError for vertical (IfcGradientCurve) and cant (IfcSegmentedReferenceCurve) segments. Bug 2 — add_zero_length_segment.py: Added a None guard before the recursive `add_zero_length_segment(file, layout.BaseCurve)` call for IfcGradientCurve. When an IfcGradientCurve is created without a BaseCurve (e.g. before a horizontal representation exists), the recursive call previously crashed with AttributeError.

DesertSpringsCivil	33a4639de5	Add Space key as alternative to Enter for PI Edit Mode apply When using G key to move PIs, Blender's transform modal consumes the Enter key. Adding Space as an alternative lets users apply changes more easily. Also adds Numpad Enter support. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-02 20:46:19 -07:00
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.
