function of .stl

I tried to use this function  (part = AsciiSTL(filename="path/to/file.stl")) as (part = AsciiSTL(newbottom="home/wardania/newbottom.stl")
but show me many different errors  
anyone knows how to enter this function in the right way to import file .stl of CAD

You are referring to importing stl files into vismach. I guess.


Try this syntax:
part = AsciiSTL(filename="home/wardania/newbottom.stl")

Note that 'filename' is an argument parameter of 'AsciiSTL()'.

what do you mean that filename is a parameter of 'Ascii'

What I mean is that the function AsciiSTL() expects an argument called 'filename'.
So if your stl file is called ABCD.stl and you want to call it say 'ABCD-part' in vismach
then you need to call the function like this:

ABCD-part = AsciiSTL(filename="ABCD.stl")

I tried to enter simplified_structure= AsciiSTL(filename="./simplified_structure.stl") like here linuxcnc.org/docs/html/gui/vismach.html

but show me this error
[Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/vismach.py", line 899, in _init_
data = open(filename, "r")
IOError: [Errno 2] No such file or directory: './simplified_structure.stl']

Is there a command to import the file or to write the file place

Looks like you have an issue with your file path there.
I presume that it expects to find the file in the same folder as your vismach python script but to be sure you might want to use an absolute path (eg. /home/user/linuxcnc/configs...) instead of the relative ./

[edit]
Just in case:
Also remember that linux is case sensitive. ( ie .stl is not the same as .STL)

Is should I put the configuration of the machine in vismach library
and then make the script
wiki.linuxcnc.org/cgi-bin/wiki.pl?Vismach

I don't think it matters where the configuration is located as long as you have the path right. Have you changed the path to absolute?
