Hello,
I would like to know how should I rotate my symbols when i deform the global geometry of the attached figure. I have some symbols which are oriented in the x axis and some which are oriented in the y axis.
in 1: tan alpha = y/x
in 2: tan alpha' = 2y/x
so the rotation is : tan-1(2y/x) - tan-1(y/x)
I think the x axis rotation is control by the cosine of rotation angle and the y axis by the sine of the rotation angle .. but i'm not quite sure.. so i welcome any help.
Thank you
