Python Script: extrude multiple surfaces to volumes

Question

Hi, 
 I am trying to use Python script in Plaxis to automate my work and I am stuck with extruding multiple surfaces to volumes: 
 here is my code: 
 
 for i in range (1000 ): 
 g_i.extrude((g_i.Polygon_i), 0 , 0 , 1 ) 
 
 the error message: 
 
 AttributeError: Requested attribute 'Polygon_i' is not present 
 
 Please note I need to extrude thousands of surfaces and it will vary based on the different problems. 
 
 Thank you very much for your reply!

Hello Kunyu 
 
 Could you try this one? It extrudes all polygons in your model. 
 for polygon in g_i.Surfaces[:]:
 g_i.extrude(polygon, 0, 0, 1)

Hello Kunyu, 
 Indeed Samet's suggestion is how I would do it. The problem is that g_i.Polygon_i is read first by Python and if you check on PLAXIS side the Polygon_i does not exist an an object. I understand of course that you try to say, first Polygon_1, then Polygon_2 with the range function but indeed the other suggestion is better. 
 Remember that the g_i.Surfaces behaves as a list, so you can also slice it to handle part of it. So, g_i.Surfaces[2:10] will consider the third object up to the 10th object in g_i.Surfaces listable.
