Summary0001886: Geometry rotation in Sketcher
DescriptionIt seems that the arc is being doubly rotated. Once around the Base and an additional time around the arc.Center.
Steps To ReproduceTry running the script below. It should result in several lobes around the point, but turns into a mess of inception-rotated arcs. It works with lines.
if(App.activeDocument() == None): App.newDocument()

f = App.activeDocument().addObject("Sketcher::SketchObject","Sketch")
ctr = App.Vector(25, 25, 0)
p = App.Placement(App.Vector(25,25,0), App.Vector(0,0,1), 45)
a = Part.ArcOfCircle(Part.Circle(App.Vector(25.292349,13.653396,0),App.Vector(0,0,1),14.931091),-2.531933,-0.416702)
l = Part.Line(App.Vector(22,17,0), App.Vector(27,17,0))

# Rotate the Geometries
for i in range(7):
   f.addGeometry(a) # rotating the arc causes weird side affects
   f.addGeometry(l) # all is good here

Sketcher: fix reversed geometry and rotated arcs

Fixes a bug where an arc, ellipse, or arc-of-ellipse, being reversed in
XY plane, behaved badly in sketcher (see forum thread "Sketch: how to
handle reversed external arcs?" ).
Also fixes a problem with rotated arcs (see forum thread "Rotating Arc
in Sketcher" ).

This is done by adding an emulation flag to a few methods in
Part::GeomXXX, which makes the shape to pretend being non-reversed
(CCW). This causes endpoints of reversed arcs of circles lineked as
external geometry to swap, causing broken sketches sometimes.

Sketch:Validation: swap endpoints for reversed + constraint orientation locking controls

Added buttons to port sketches to CCW-emulation Sketcher.

Bonus =) : Added constraint orientation lock/unlock buttons (affects
point-wise modes of tangent and perpendicular constraints so far)
