New attachment modes:
"Align O-Z-X"
"Align O-Z-Y"
"Align O-X-Y"
"Align O-X-Z"
"Align O-Y-Z"
"Align O-Y-X"
They allow to attach a sketch by picking origin point and sketch axes
directions.
... by verifying if the pointers equal to objects contained in all open
documents. Not terribly good, but I can't think of a situation where
doing this search might cause trouble.
When another bit of information was needed to be extracted from mode
suggestion routine, it felt like listMapModes had too many arguments.
So, the arguments have been collapsed into a struct. This triggered a
few namespace-related changes, which lead to massive search-and-replace
changes all over FreeCAD.
So the only functional change carried out is the addition of reference
types readout to info returned by suggestor.
Modes added:
3D and plane attachment: Inertia CS
Line attachment: Inertia axes
This commit may serve a good example of how to add new attachment modes.
Attachment mode list used to display only the modes that fit current
references. Now, modes that can be reached by adding more references are
listed too, but grayed out.
* propose attachment modes
* refactor setUp and Copy
* split off postprocessing from 3D to reuse in 1D and 0D calculations
* AttachableObject: fix error printout in onChange
* AttachableObject: no more defaults to Attacher3D
* implementation of lines and points attachment (some of the proposed modes).
* refactor getShapeType, add getShapeType(obj, sub); add a flag to eRefType enum, indicating that referenced thing is a whole object that has placement.
* change readLinks to be static, and obtain shape types in the process.
* test mode enums lengths equality
* extend ObjectXY to work on conics.
* Fix upside-down sketches attached as TangentPlane on most shapes.
* Fix crash when a shape of unlisted type is in the links.
* fix attaching to datum lines go crazy because of infinities.
* abs->fabs
* support for App::Line
* Add namespace qualifiers to TYPESYSTEM_SOURCE-like stuff
