I don't like this angle of Line :

I want the line to have the angles that I'm inserting .... (0 ، 45 ، 90 ، 135 ، 180 ، 225 ، 270 ، 315 , 360)

in other words:

(I want the angle of line must be : 0 ، 45 ، 90 ، 135 ، 180 ، 225 ، 270 ، 315 , 360 )

Like these :

Sorry I can't speck English Very well !

Try to insert in event 5 as second action (after the set angle toward):

stroke|Set angle to round(stroke.angle/45)*45 degrees
