* 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: Correct user warning The operation can indeed be undone.

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.
-
Designed for your needs FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture, whether you are a hobbyist, programmer, experienced CAD user, student or teacher.
-
Cross platform FreeCAD runs on Windows, macOS and Linux operating systems.
-
Underlying technology
- OpenCASCADE A powerful geometry kernel, the most important component of FreeCAD
- Coin3D library Open Inventor-compliant 3D scene representation model
- Python FreeCAD offers a broad Python API
- Qt Graphical user interface built with Qt
Installing
Precompiled packages for stable releases are available for Windows, macOS and Linux on the latest releases page.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For weekly development releases visit the releases page.
Other options are described on the wiki Download page.
Compiling
FreeCAD requires several dependencies to correctly compile for development and production builds. The following pages contain updated build instructions for their respective platforms:
