onChanged() triggers for the first time before all of the properties are
loaded, so it can fail to compute properly at that stage, depending on
the load order.
However, it's not necessary to compute geometry in onChanged() at all,
because that's usually supposed to happen in execute() anyway. The
solution here is to just not do onChanged() at all.
Fixes#13558
Since Py3.11 the methods names __setstate__ and __getstate__ conflict with the method names added to the object class.
Thus rename them to 'loads' and 'dumps'
OCCT 7.3 did not work well when using a very large projection plane, so
this commit reduces the plane size to the minimum required for the cut
operation. It also performs some minor refactoring in anticipation of
the implementation of the true projection feature, and it removes the
last attempted fix, which proved unnecessary.
Address a hang when using older versions of OCC to create a rotated
extrusion. This approximates the auxilliary spine as set of line
segments formed from the helix, rather than using the helix directly.
As pointed out in Issue #0004353 the OpenSCAD Workbench does not
correctly implement the angle parameter to rotate_extrude (it's a
relatively recent addition to OpenSCAD), nor does it attempt to do
anything with a specified $fn. This commit adds both features. To add
$fn handling, the code from the cylinder extrusion was mimicked,
allowing FreeCAD to create perfect, smooth representations when $fn
exceeds a user specified value in Preferences, but attempting to create
OpenSCAD's more discrete representation when using a lower $fn. Note
that this determination is made at creation time: if the user later
increases the segments parameter in the new object, it will remain
prismatic regardless of how high the value is made.
Modify the auxiliary spine to be a true helix, resulting in a much
smoother linear extrusion when a twist angle is applied. This also
corrects a bug in the scaling during linear extrusion, where non-uniform
scaling was not handled correctly.
The original implementation of the surface() function used a simple
B-spline representation for the surface, which generated degenerate
surface with several of OpenSCAD's demo input files. This commit
modifies the algorithm to generate a discrete surface identical to the
one generated within OpenSCAD itself. It also adds several units tests
to identify future regressions.
Note that PNG input is not yet supported for the surface() function.
