If you only could see my experimentation...like a mad scientist...
The permutations are many.... 1/4 scale, 1/2 scale... etc.,. I did not ask my question correctly. My question is if there was a global policy for behavior for such as this. For example, I can change the default for 1/4 to "centers", but it looks like I would have to change the 1/2 scale seperately. From what I can tell, the CL tool will not function unless you set the default, which is counter to minimzing default changes just to get a tool to position properly.
As I learn the details it will flush out, and I suppose one does not really change scales often, or framing defaults, so probably not an issue. A table of defaults on which defaults cascade, or don't would be very helpful for a newbie.
