System Options

Hello,

I have a few general questions about some system options>sketch area.  One of the check box descriptions "Use fully defined Sketches" has brought some attention to me.  I am making a new template and am wondering if I should check this box or not.  I dont really see why I would not.  If there are some reasons that this would become a problem please let me know if you have encountered issues in the past.

While I am asking a question I mine as well ask something else I have been thinking about.  I often use the same parts for many types of documents.  It's set up that if I change a part that is in an assembly it will also change.  I like that feature.  However, it gets kinda nuts.  I save the generic part and do not edit it.  If I want to use it for something I will open it and save as another part which I will use in an assembly usually.  That way the original is not edited.  I often edit the same part in different ways dozens of times so I have dozens of that edited original part saved dozens of times as well.  Is this the way I should be doing this (save as approach).  I have to label the filename very descriptively to find the one I should use. 

Thanks,

Brian
