dear group members

I know how to construct polygons with linear boundary segments.

So here is a short python expample:

array = arcpy.Array()

coordinates=['some data']

for coordinate in coordinates:

array.add(arcpy.Point(coordinate[0], coordinate[1]))

array.add(array.getObject(0)) #close polygon

polygon = arcpy.Polygon(array)

please, is there some advice on how to construct a polygon boundary with circular arc segments alternating with linear segments using python & arcpy?

thank you

no mention of python here Changing a segment into a straight line, a circular arc, or a Bézier curve—Help | ArcGIS for Desktop

nor is there an arc geometry objec Geometry—Help | ArcGIS for Desktop

perhaps if you could elaborate on what you are trying to do, then a solution might be at hand. Circular arcs can be replaced by densified line segments and would suit most situations unless you are trying to replace CAD functionality
