creating polylines from a point with specific azimouth

Kostas

Hello i have a point and i want to create polylines for every 5o from 180o to 360o (north azimuth). How can i do that with azimuth and bearings?

Here's how you can automate this with arcpy geometry objects:

>>> import math
>>> length = 100000
>>> lines = []
>>> degrees = 5
>>> with arcpy.da.SearchCursor("YOUR_POINT_LAYER_NAME_HERE","SHAPE@") as cursor:
...    for row in cursor:
...        for i in range(360/degrees):
...            dx = math.cos(math.radians(i*degrees))*length
...            dy = math.sin(math.radians(i*degrees))*length
...            startPoint = row[0].centroid
...            endPoint = arcpy.Point(row[0].centroid.X+dx,row[0].centroid.Y+dy)
...            line = arcpy.Polyline(arcpy.Array([startPoint,endPoint]))
...            lines.append(line)
...           
>>> arcpy.CopyFeatures_management(lines,'in_memory\lines')

edit: I just read the point about limiting between 180 and 360. This can be incorporated into the above script.
