* BIM: Implement smart base removal for Walls Previously, removing the Base object from an Arch Wall would cause the wall to reset its position to the document origin and could lead to unintended geometric changes for complex walls. This commit introduces a "smart debasing" mechanism integrated into the Component Task Panel's "Remove" button: - For walls based on a single straight line, the operation now preserves the wall's global position and parametric `Length`, making it an independent object. - For walls with complex bases (multi-segment, curved), a warning dialog is now presented to the user, explaining the consequences (shape alteration and position reset) before allowing the operation to proceed. This is supported by new API functions `Arch.is_debasable()` and `Arch.debaseWall()`, which contain the core logic for the feature. Fixes: https://github.com/FreeCAD/FreeCAD/issues/24453 * BIM: Move wall debasing logic into ArchWall proxy The logic for handling the removal of a wall's base object was previously implemented directly within the generic `ComponentTaskPanel` in `ArchComponent.py`. This created a tight coupling, forcing the generic component UI to have specific knowledge about the `ArchWall` type. This commit refactors the implementation to follow a more object-oriented and polymorphic design: 1. A new overridable method, `handleComponentRemoval(subobject)`, has been added to the base `ArchComponent` proxy class. Its default implementation maintains the standard removal behavior. 2. The `_Wall` proxy class in `ArchWall.py` now overrides this method. All wall-specific debasing logic, including the eligibility check and the user-facing warning dialog, now resides entirely within this override. 3. The `ComponentTaskPanel.removeElement` method has been simplified. It is now a generic dispatcher that calls `handleComponentRemoval` on the proxy of the object being edited, with no specific knowledge of object types. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * BIM: Add interactive creation of baseless walls Introduce a new workflow for creating Arch Walls without a dependency on a baseline object (e.g., a Draft Line). - The `Arch_Wall` command is enhanced with a "No baseline" mode, controlled by a new "Walls baseline" preference, allowing users to create placement-driven walls directly in the 3D view. - The existing `debaseWall` function has been refactored for correctness and consistency with the new baseless wall geometry. Co-authored-by: Yorik van Havre <yorik@uncreated.net> * BIM: Refactor structure of the Arch Wall command Refactor the `Arch_Wall` GUI command (`BimWall.py`) for improved readability, maintainability, and architectural clarity. - A `WallBaselineMode` Enum is introduced to replace the original integer values, making the code self-documenting. - The monolithic `create_wall` method is broken down into smaller, single-responsibility helper functions for each creation mode. - The `addDefault` method has been removed, with its logic integrated into the new structure. * BIM: Add Draft Stretch support for baseless walls This commit makes the new baseless Arch Walls graphically editable using the `Draft_Stretch` tool. - An API for stretching (`calc_endpoints` and `set_from_endpoints`) has been added to the `ArchWall` proxy. - The `Draft_Stretch` tool is now aware of baseless walls and calls this new proxy API to perform the stretch operation, enabling users to stretch them.

The calculated local placement of the wall is now correctly transformed into the global coordinate system by multiplying it with the working plane's placement. * BIM: Ensure unique baselines for subsequent wall creation Fixes a bug where creating multiple walls with baselines would incorrectly reuse the same underlying Sketch or Draft Line object. The object retrieval logic after the `doCommand` call now correctly uses `ActiveObject` to get a reliable reference to the new object instead of relying on a hardcoded name. * BIM: Make the wall's base object label translatable * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * BIM: use singular for consistency with other labels Co-authored-by: Roy-043 <70520633+Roy-043@users.noreply.github.com> * Fix typo * BIM: address reviewer's comments about improving object reference passing between Python and FreeCAD contexts, and functions * BIM: remove defensive programming: the callback is only executed as a result of a user's GUI action * BIM: use the params API to define WallBaseline parameter * BIM: add Arch Wall tests for joining wall logic * BIM: add joining logic * BIM: re-add ArchSketch support * BIM: re-add multimaterial support on wall creation * BIM: address CodeQL warning, remove module duplication * BIM: fix check for SketchArch module when creating sketch-based walls --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Yorik van Havre <yorik@uncreated.net> Co-authored-by: Roy-043 <70520633+Roy-043@users.noreply.github.com>

Overview
-
Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters.
-
Create 3D from 2D and back FreeCAD lets you sketch geometry-constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings.
