doc.py has a dictionary. When the user describes a wall, it is passed 
to the doc object to be saved in the dictionary.

I guess my description does not come across well.

I thought user.py sounded like it is, a user created file. It will be 
named differently for each user to created different types of 3D 
objects. It does not make sense to expect every user to name their 
design file the same. So there will have to be a differently named 
single argument for buildeswin.

No. appwin opens an opengl (pyglet.window.Window()) graphics window as 
I mentioned.

I have tried importing "user.py" and/or "app.py". However there is no 
single command to call.

My program is designed to assist in the building design process. It is 
a big program and the creation of building components takes quite a 
few steps. I do not want to support these steps in a graphics window 
which is why the user uses any text editor they prefer to create 
"user.py". I want "appwin.py" (which has a graphics window) to be able 
to access objects stored in "doc.py" (which has a dictionary) after a 
command like "python user.py" so that the objects saved in "doc.py" 
after execution can be retrieved and drawn in "appwin.py".

This is a command that the user can enter in user.py. app.py will then 
encounter this command as python parses the file.

I have tried this but there are no objects found in the dictionary in 
doc.py. I am guessing that I have to execute appwin.py so that it 
shares the same namespace with user.py or maybe a way to access that 
namespace. This is the reason for my question.
