Is it possible to change the angle of a hatched fill in a fill symbols layers through ArcPy.mp? I can get at the main appearance properties such as color and outline. I want to angle of the hatch on one or two layers of the symbol (hatch and cross hatch.) The reason is I need to un-rotate the map rotation so a horizontal line remains horizontal (since the symbology I have to implement uses horizontal, vertical, diagonal and cross hatch meaning different values.) Rotating the fill symbols with the map changes all the values represented in map. I am looking to automate some of map making tasks for the users. Rotating 5 symbol levels on 30 different layers for 5 different maps in a set must be automated,
I found a workaround of creating custom coordinate systems with the central meridian (for conic and stereographic) that aligns with the desired data frame rotation and then remove the rotation on the data frame. That way I don't have to do this.
