newbie questions on visual mill

Hello
I just started trying to use visual mill and have 4 question. Any help
would be appreciated.

1. In the help index when you click on create it says there is no page to
be found. Is this a bug?
2. Can you resize your cad project bigger or smaller for post processing in
visual mill.
3. How can I switch over to millimeters from inchs or is that again specfic
to the cad model.
4. how does the different operations i.e roughing, finishing work in the
post processor. I have a taig mill which does not have a tool changer, does
each operation stop and wait for an operator command or is it continuious.
and you have to break up the cam operations.

Thanks
Steve Ross
