Can you create a polygon object from a file(Text file)
if I have the polygon structure of a object and put it in a Text File, can I recreate it with python from that Text File.
Is this even possible ????

Of course, read the file with all the information and create the object based on that input.
E.g. a cube shaped object could be like:
recube = c4d.BaseObject(c4d.Opolygon)
recube.ResizeObject(8,6) #8 vertexes (points) and 6 polygones
recube.SetPoint(0,vertex1)
recube.SetPoint(1,vertex2)
recube.SetPoint(2,vertex3)
recube.SetPoint(3,vertex4)
recube.SetPoint(4,vertex5)
recube.SetPoint(5,vertex6)
recube.SetPoint(6,vertex7)
recube.SetPoint(7,vertex8)
recube.SetPolygon(0,c4d.CPolygon(0,1,2,3))
recube.SetPolygon(1,c4d.CPolygon(4,5,1,0))
recube.SetPolygon(2,c4d.CPolygon(7,6,5,4))
recube.SetPolygon(3,c4d.CPolygon(3,2,6,7))
recube.SetPolygon(4,c4d.CPolygon(1,5,6,2))
recube.SetPolygon(5,c4d.CPolygon(0,4,7,3))
recube.Message (c4d.MSG_UPDATE)

This code above I want python to read it for me from a file and then create a object from it.

I want to do these steps in python:
1] Create a empty polygon
2] Import the points from a ASCII File
3] Import the polygons from a ASCII File
Basically build the object from these steps in python
I see you can almost achieve this with call commands
import c4d
#Welcome to the world of Python
def main() :
c4d.CallCommand(13039) # Empty Polygon Object
c4d.CallCommand(12530) # Points mode in Structure
c4d.CallCommand(13018) # Import ASCII Data (Points)
c4d.CallCommand(12532) # Polygons mode in Structure
c4d.CallCommand(13018) # Import ASCII Data (Polygons)
if __name__=='__main__':
main()

I used the following input files. One for points and one for the polys.
I got these files by exporting a cube data to these files.
Later I edited the files, to add some ",".
But you can choose the format you want.
Point file:
Point X Y Z
0, -100, -100 , -100
1, -100 , 100 , -100
2, 100, -100 , -100
3, 100 , 100 , -100
4, 100 , -100 , 100
5, 100 , 100, 100
6, -100, -100, 100
7, -100 , 100 , 100
Polygon file:
Polygon A B C D
0, 0, 1, 3, 2
1, 2, 3, 5, 4
2, 4, 5, 7, 6
3, 6, 7, 1, 0
4, 1, 7, 5, 3
5, 6, 0, 2, 4
