* Draft: make move, rotate and scale commands link-aware Fixes #12836. Fixes #15681. These changes are presented as a single ('big') PR because the mentioned commands have several similarities. Working on them seperately would have made less sense. The commands have been made 'link-aware' meaning they can now handle Links and objects in linked containers. This required several changes in the following main files. For each command all options are handled by a single function now (the `move`, `rotate` and `scale` functions). This was the only reasonable solution to correctly handle nested placements. As a result there is no longer a need to build very complex 'cmd' strings in the gui_*.py files (which is a good thing IMO). Main files: * move.py * rotate.py * scale.py * gui_move.py * gui_rotate.py * gui_scale.py * gui_trackers.py The following files have also been updated: * Draft.py: Imports updated. * DraftGui.py: If `CopyMode` is changed the ghosts have to be updated. The move and rotate commands now also show previews of movable children. But since those are not copied they should be removed from the ghosts if `CopyMode` is changed to `True`. * utils.py: Some helper functions have been added. An existing helper function (only used internally) has been renamed. * gui_utils.py: The `select` function has been updated to accept a list of tuples to allow the reselection of nested objects. * clone.py: A new property `ForceCompound`, necessary for non-uniform scaling, has been added. * join.py: The `join_wires` function now returns the resultant wire objects. * task_scale.py: Updated to allow negative scale factors. Support for `SubelementMode` preference added. * dimension.py: `transform` methods added. * layer.py: `get_layer` function added. * svg.py: Updated to use `get_layer`. * view_text.py: Instead of two added `coin.SoTransform()` nodes the main transform node is used instead. This was done so that ghosts of Draft Texts can be handled properly without requiring dedicated code in gui_trackers.py. Notes: * Support for "App::Annotation" is limited. Only their `Position` is handled (by the move and rotate commands). * Support for "Image::ImagePlane" has been removed from the scale command. The object has its own calibrate feature (see https://wiki.freecad.org/Std_Import). * Copies and clones are always created in the global space. * Fix several unit test issues. * Reset value that was changed while testing * Rebase and update test_modification.py * Reintroduce scaling of image planes

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 to 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 Releases page.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For development releases visit the weekly-builds 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:
Reporting Issues
To report an issue please:
- Consider posting to the Forum, Discord channel, or Reddit to verify the issue;
- Search the existing issues for potential duplicates;
- Use the most updated stable or development versions of FreeCAD;
- Post version info from
Help > About FreeCAD > Copy to clipboard; - Restart FreeCAD in safe mode
Help > Restart in safe modeand try to reproduce the issue again. If the issue is resolved it can be fixed by deleting the FreeCAD config files. - Start recording a macro
