When the ellipse to be projected and the sketch plane are parallel, the original code
by shermelin provided for a translation of the original ellipse, which would be the best solution
if it weren't because the Sketcher, internally, works under the assumption of a normal vector to the
sketcher plane being (0,0,1). If the original ellipse is parallel to the sketch plane, but the sketch
plane is not the XY plane, the copy and translation would result in a ellipse not in the XY plane of the
Sketcher. Then the sketcher internals will not properly consider its dimensions.
The solution applied here is to default to the general method for non-parallel planes.

Users chennes and hyarion made me aware of this covereity issue:
Fixes Coverity: geoit can be end() when dereferenced
https://github.com/FreeCAD/FreeCAD/pull/4429/files#
When analysing the block where the dereferrencing appears, it
appears that it is a left-over that no longer makes sense:
- The algorithm classifies block constraints into those that are
not affected by any other driving constraint and those that are
affected by other driving constraints.
- The offending block deals with internal aligned geometry, thus
per definition has a driving internal alignment constraint, for which
the previous block already set the need of post-analysis.
- No matter what, the geometries, the complex one and the internal one
will have at least the driving internal alignment constraint, so they
cannot become "not affected by any other driving constraint".
- If the geometry had a block constraint on it, it was already added for
post-analysis in the previous block. If it did not have one block constraint,
the fact that it is internal aligned geometry is an irrelevant consideration.
Probably there was a point during development when this made sense, but with
the current post-analysis, it does not appear to make sense anymore. So the
block was removed.
This commit adds a unit test for blocked geometry (new block constraint).
Before the throughall distance was 10 m, which is not enough for
many applications. The fix is to use the bounding box of the base shape
together with the sketch profile to calculate dynamically a large enough
length.
* reimplement ViewProviderDimension::setupContextMenu() to show menu item to start editing it
* fix TaskDimension::accept() and TaskDimension::reject()
For the What#s this feature we need to have a uniform naming of the features and its icons. For some PD icons this is not the case and since we are in feature freeze, this is the right time to address this.
(I see the same is already done for Mesh.)
Fixes Coverity issue:
CID 316539 (#1 of 1): Uninitialized scalar field (UNINIT_CTOR)
uninit_member: Non-static class member lastHasPartialRedundancies is not initialized in this constructor nor in any functions that it calls.
=================================================
Knot position is not calculated by the solver, but by OCCT when updating the
b-spline to conform to given pole positions, as mandated by the solver. Before
this commit, all constraints driving and non-driving operating on the knots required
and extra solve (from advanced solver dialog, or from the Python console), or a recompute
to be recomputed.
This commit introduces transparently re-solving at Sketch.cpp level if B-Splines are present,
so that when the Sketcher mandated solve returns, the geometry is fully solved.
The "angle" variable was not being initialized in any of the
constructors for the CutDimensionSet, and nothing was being initialized
by the default constructor. This commit adds angle as an optional final
argument to the parameterized constructors, defaulting to 0.0, and adds
default values to the default constructor using the first of each enum
and 0.0 for the angle. The default constructor is required elsewhere in
the code so cannot be trivially removed. Issue identified by Coverity.
LGTM complains if this calculation is done from inside the sqrt() call
because it sees the explicit cast to float and assumes that sqrt() is
intended to take a double. By adding an intermediate step it should be
clear to LGTM that the float version of sqrt is intended.
========================================
The geometry state stored in the geometryFacade is modified following a mutable model
(without setting the Geometry property on Constraint change), in order to avoid coupling
the addition/removal of a constraint with a change of the Geometry Property.
This design decision however interferes with the ability of the Geometry property to restore
the correct geometry state upon redo/undo.
While such a situation is rare in the case of Internal Alignment geometry, because constraint
addition/removal is performed with the corresponding geometry addition/removal (within the same
transaction. That is not the case with the Block constraint (or another future general case where
the geometry state may be applied).
This commit leverages the synchronisation mechanism already in use for non-properties (e.g. external geometry or
vertex indices) to check and synchronise geometry state upon undo/redo and restore.
Bonus:
- addGeometryState is refactored to separate the checking logic from the setting logic.
In some PartDesign task dialogs, the destructors call functions that may
throw exceptions. If that occurs and the exception is uncaught, this
will ususally end up terminating the program. This commit adds try-catch
blocks around each instance of that (identified by Coverity) and handles
the Python exception in the normal reporting workflow.
