@Buckwheat How do you avoid panning and transform ( Zoom ) for those site scale and compass rose ?

Found the solution: Use painter.resetTransform().

@alex_malyu

Thank you for the ideas. I will keep this in mind.

Hi and thanks for hints. We were thinking also about local coordinates of arc being drawn. But considering that when drawing arc in its local space using global scene coordinates and then adding arc into scene at 0.0 would be the same as drawing arc in its local coords at 0.0 and then placing it at some position.
Considering we don't rotate which we don't at this time...

Will try to draw at 0.0 and translate in scene afterward. lets see if that'll make a difference.

My point is simply that blind adherence a principle or method can actually be worse than fully understanding the needs and goals of what you are trying to do.

Amen.
