Support for creation of Rotation from matrices which is a combination of non uniform scale and a rotation
Fixes according to review
Scale -1 is Uniform, Not NoScaling
Fix hasScale() when negative scale
- define materials so that they are recognized by material handling as existing card
- use "electrodynamics" as equation because this is the common name for the physics of these examples
- fix typos
The arcs on the tip (around the addendum) and the root (between the
fillets) used to have their bulge in the wrong direction for the internal
gear profile: their center points has been on the outside.
Since this error existed since the very first introcution of the internal
gear I assume this was done by accident: Instead of only the fillets, all
arcs have been inverted when the external profile was copied.
This commit now inverts the tip and root arcs again, to be concentric
with the pitch circle -- same as for the external profile.
- for some materials, just opening the material dialog and pressing OK to close it without any change resulted in a transient material
- for other materials this happened by clicking in the material dialog on a value to edit it, but not changing anything and press OK
The fix is to compare the items item by item and also handle the case that only digits of numbers are different
This PR fixes the long-standing major bug that for languages using ',' as decimal separator the material editor was useless. (bug no. 10 in https://forum.freecad.org/viewtopic.php?t=56912)
the issue was that the value was handled as text. This PR:
- using a spinbox instead if a text edit to modify numbers (has also the advantage to be able to change values by spinning)
- sets min/max properly for all number data types
- also avoid rounding artifacts when changing Float values
As the property descriptions are translated at a central place in the
GUI, we have to use the generic "App::Property" category.
For details see https://tracker.freecadweb.org/view.php?id=0002524
As the property docs are also used as tool tips in the InvoluteGear's
task panel, this is also needed to achive a fully translatable GUI.
In order to not maintain the same information in two places, the property
docs are reused as tool tips for their input fields. And for user
convenience, the same tool tip is assigned to the respective label as
well.
