Until this commit, B-Spline knots were stored, and checked at solver level as sketch points GeomPoints having the
construction status set to true.
This behaviour is removed to eventually enable normal non-construction points to define the shape out of edit mode.
This commit leverages the new mechanism for the solver interface.
===========================================================
The introduction of the ability of the geometry extensions to store information leads opens new
possibilities to the sketcher, which may require migration of previous versions of the sketcher.
A striking example is the migration of the GeomPoint+Construction to mark a B-Spline knot to a proper
geometry state based on the sketch geometr extension.
It also enables to make aware the geometry of the Blocked status, by restoring the geometr blocked
status.
This commit defines an scheleton for this mechanism.
=============================================================================
Minor refactoring to centralise string to enum conversion in a single place
============================================================
This commit extends SketchGeometryExtension to store within a Geometry if it is an internal aligment geometry
and which type.
====================================================================
If the Part::Geometry * is nullptr, then it is convenient to have a
std::unique<GeometryFacade> that contains a nullptr too, because many
functions check for a Part::Geometry being a nullptr.
======================================================================
GeometryFacade is added the ability to get the construction status via static function, for
convenience in situations where only the construction status is necessary and a geometry facade
would not be otherwise necessary.
A new type GeometryTypedFacade is added, for situations in which the specific Part::Geometry derived
type is known (or is to be created). This Typed version enables to directly access the Geometry derived
class without the need for casting, as well as the SketchGeometryExtension information.
For example, this is possible:
auto HLineF = GeometryTypedFacade<Part::GeomLineSegment>::getTypedFacade(HLine);
HLine->getTypedGeometry()->setPoints(Base::Vector3d(0,0,0),Base::Vector3d(1,0,0));
If a facade is requested without passing an Part::Geometry derived object, the constructor
of the indicated geometry type is called with any parameter passed as argument (emplace style):
auto HLine = GeometryTypedFacade<Part::GeomLineSegment>::getTypedFacade();
HLine->getTypedGeometry()->setPoints(Base::Vector3d(0,0,0),Base::Vector3d(1,0,0));
HLine->setConstruction(true);
ExternalGeo.push_back(HLine->getGeometry());
Using either GeometryFacade or GeometryTypedFacade is probably a matter of style and of the specific situation.
========================================
This is a light-weight c++ only geometry extension to enable migration of information that was stored within
the Part WB and should be migrated to another WB (for example Sketcher WB)
It is designed so that a single extension can migrate different types of data (current and future).
When new data needs to be migrated, first a new enum bit is to be added to the class enum and new data members are to
be added to store the information within GeometryMigrationExtension class.
In the Restore() function restoring the data to be migrated, a GeometryMigrationExtension extension is added to the
geometry to be migrated with the data information and the corresponding enum bit set.
In the object to receive the migration data, onDocumentRestored() it is checked whether an extension of type
GeometryMigrationExtension is present, if yes, it is checked whether a bit used for migration is set and, if yes,
the data is retrieved and the GeometryMigrationExtension extension (preferably) removed from the Geometry object.
===================================
Encapsulate Part::Geometry data member copy process in a single function (copyNonTag).
Part::Geometry derived classes need not know the specifics of the data member of Part::Geometry.
Change the delegation of the copy of extensions from clone() to copyNonTag. Because clone() relies on
copy() and now copy() of Part::Geometry data member relies on copyNonTag(), there is no actual change
to the clone() functionality, but the copy() funcionality gains the copy of the extensions via copyNonTag().
When exporting a hidden TechDraw::Page with exportPageAs[Pdf|SVG] a
Segmentation Fault occured.
The return value of getMDIViewPage() was only checked for the first call, but
not for the second call. showMDIViewPage() silently returns, when the
TechDraw::Page is hidden and does not load the page.
The regular expression that Draft's airfoil data importer uses did not allow for lowercase "e" when using scientific notation. This corrects that, and silences Python Developer Mode warnings about deprecated escape sequences by converting most of the regex to use raw strings.
This commit adds SVG files with icons for these commands. Also, it makes the necessary changes on CommandDoc.cpp, CommandWindow.cpp, CommandStd.cpp and resource.qrc files.
