Re: [Visualpython-users] bug in vpython path library

[Eric Z. <zar...@gm...>]

Can you share the part of the code in which is made the extrusion?
and if is possible, upload an image and post the link. I had a similar 
problem before, but for don´t talk on the air, is better to see the 
example and try to find the specific solution.
Eric.
