In this tutorial we create class to construct a polygon. Again, this is a pretty simple example but we define a few additional methods for our class to extend it's functionality.

```import rhinoscriptsyntax as rs
import math

class MyPolygon:

self.sides = sides
theta = (2*math.pi)/self.sides
print theta
pts = []
pts.append(pt01)
self.origin = [0,0,0]
degrees = theta*(180/math.pi)
print degrees
for i in range(1,self.sides):
tempPt = pts[-1]
newPt = rs.RotateObject(tempPt,self.origin,degrees,None,True)
pts.append(newPt)
pts.append(pt01)

def fillPolygon(self):

def extrudePolygon(self,height):
startPt = self.origin;
newZ = self.origin[2]+height
endPt = [self.origin[0],self.origin[1],newZ]
return rs.ExtrudeCurveStraight(self.polygon, startPt, endPt)

polygon1 = MyPolygon(5,5)
polygon1.fillPolygon()
polygon1.extrudePolygon(5)
polygon1.createPolygon()

polygon2 = MyPolygon(12,8)
polygon2.createPolygon()

polygon3 = MyPolygon(15,3)
polygon3.createPolygon()```
