========================================
Fonts:
- SoDatumLabel internally uses QFont and thus points. It was being fed pixels, for which the configured size in preferences did not match the actual on screen size. This is corrected.
- Font sizes fed directly from parameters to the coin nodes skeleton were not being updated, as the parameter observer is initialised after the nodes are created, and the parameter
observer was not configured to update this nodes. This is corrected.
Colors:
- Some color parameters were not being being updated by the parameter observer. This is corrected.
- To speed up analyses one calculates on several CPU cores. The result is a partial VTU file.
Unfortunately when applying a transparency the boundaries of the volumes computed by each CPU core are always visible. This makes it often unusable for visualizations.
The solution is to filter the results the same way a clip filter does.
- the ViewProvider sorting of the field can be different from the sorting in the dialog
- also hide a Contours property (I forgot this when the contours filter was added)
* [Arch] fix Arch_Stairs recompute issue
* Fixed the tooltips for the updated properties.
* Added warnings to the functions that updated the properties.
* Fixed a typo makeCurvedStairsWithLandings -> makeCurvedStairsWithLanding
- sort the functions alphabetically to know where to scroll to - eases the reading at least a bit
- some automatic reformatting according to our current clang file
- split too long lines
- no longer output an error on mesh from a BooleanFragments. There are cases when this fails, but other cases where one must use a BoopleanFragments compound and this works well, see https://forum.freecad.org/viewtopic.php?t=71070. Therefore a warning is sufficient.
- disable log messages not important for the average users.
- avoid code duplication
Previously, the fillet started at a fixed value, tailored at 20° pressure
angle, a fillet radius of 0.375 and a dedendum of 1.25. With PR #8184
those values became user-adjustable and thus the assumptions of the
original code are not fullfilled any more. This resulted in significant
artefacts, especially for higher pressure angles or smaller dedendums as
commonly found in splines.
This commit actually calculates the junction between fillet and involute
so that the tangents of the both curves match.
The mathematical approach is described in source code comments.
The change in the fillet calculation also affects compatibility with
files generated by earlier versions of FreeCAD. Those changes are way
below 0.1% per tooth, however the earlier test required absolute equality
down to the micron. This was relaxed and also changed to a relative, per
tooth, tolerance.
There is one particular case where the new algorithm performs slightly
worse, though. That is when the fillet radius is too large to the
dedendum, i.e. resulting in a single arc instead of two fillets, and
effectively cannibalizes some of the clearance. This happens with internal
gears having less than 25 teeth. At about 15 teeth it becomes visible
that the fillet is not 100% tanget any more. However, as such a low
number of teeth is highly unusual for internal gears and the effect,
although noticeable, is minor, the overall benefits of the new algorithm
outweighs the drawbacks. And now with the fillet radius being adjustable
it is easy to fix, too.
The technical reason is that the tangency is calculated correctly, but
the fillet circle is displaced aferwards to avoid an overlap of the two
fillets. For the new fillet position, the tangents do not align any more.
This little script has proven to be a vauable debugging aid, so it got
some love. All the new properties from #8184 can now be set, together
with the option to generate internal gears.
- it is a well-known and often feed-backed missing feature that SectionCuttings fails for intersecting objects.
To resolve this, the objects must be put int a BooleanFragments object.
- this PR adds this functionality as option.
- since a BooleanFragments objects has a specific color, the different colors of the objects cannot be preserved. Because of this disadvantage, the BooleanFragments option will not be the default.
- this PR also modernize all for loops
