Fixes: #7387.
See comment: https://github.com/FreeCAD/FreeCAD/issues/7387#issuecomment-2915599566
PR to change the base object of BezCurve, BSpline and Wire to `Part::FeaturePython`. This will only affect new objects. So code will have to also keep handling the old object type (`Part::Part2DObjectPython`).
The modification of BimPreflight.py needs to be verified. The steps in the old code lacked logic IMO. But I may have misunderstood.
Fixes#16333.
Follow-up of #19487.
* The functions have been made nesting-aware. New objects are put in the same container (Group, Part) as the original objects. As a consequence for some operations the original objects must be in the same container as well.
* New objects receive the visual properties of the original objects. This is not always perfect. For example when upgrading to multiple wires there is currently no check to see which edge came from which orginal object. The fact that the `format_object` function is called from the Draft `make*` functions is problematic here. If construction mode is active `make_wire` puts new objects in the construction group and we don't always want that. This has been solved with a workaround (see 'cludge' in the code).
* The 'de-parametrize' downgrade option has also been enabled for features of PartDesign Bodies that have the `Profile` property.
* Before deleting objects there is a check to see if they are in use elsewhere (`InList` check). Base objects of arrays are not deleted if they are visible. If a PartDesign Body, or an object inside a Body is selected, the whole Body is deleted.
* The force options did not work for functions that take a single object.
* The `getShapeFromMesh` function in ArchCommands.py could return a solid that was not closed. A check for that has been added.
* 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
Fixes#16210.
Note that `Draft.format_object` is called from gui_split.py (in the commit). This is not consistent with other tools where this is handled in the `make_*` functions. In this case the new object is formatted twice. The 1st time by the `make_wire` code which (wrongly) applies the current default props.
Forum topic:
https://forum.freecad.org/viewtopic.php?t=92476
For LinkGroups and Links to Std_Groups that do not have a default placement, a temporary hidden document is used to handle the placement of their children. This is a bit of a hack of course.
The fix in #16212 only checks the LayerContainer for layers. Since we do not stop users from moving layers out of that container, we should search the whole document instead.
Fixes: #16201.
Uses new material system for appearance
Each feature object now has a property called ShapeMaterial that
describes its physical properties. If it has a shape, it has a
material.
The ShapeColor attribute is replaced by a ShapeAppearance attribute.
This is a material list that describes all appearance properties, not
just diffuse color. As a list in can be used for all elements of a
shape, such as edges and faces.
A new widget is provided to allow the user to select materials in a
consistent fashion. It can also launch the material editor with its
more advanced capabilities.
These messages were perhaps originally intended as a debuggin aid but now add clutter to the output panes. Remaining messges are mostly the result of methods to display attributes of an object (which one could call from the Python console) or actually provide some information which would not be obvious from the circumstances
