So how do you, One,see the dam little's to align them? I cannot seem to get close enough and have to keep switching back and forth in views to assure lining them up. They look lined up then I switch positions and realize that it is a 2d optic and it is not lined up.
Second, how to you get the smalls lined up because the 0.01 resolution depends on where the part is placed to move it and get it lined up? I typically start with a 'snap' so it aligns then move it.
Double tap "Y" to toggle zoom mode which makes it a bit easier to pick the pivot point you want. Then I go into manual position mode, scale the new piece down and then use manual pivot selection to line them up. The green pivot marker gets in the way when you're working that tiny so often times it ends up being a lot of trial and error to get it right.
Red and I had talked in a thread on the steam forums about the possibility of having that green pivot marker be able to be toggled on/off to make it easier to see when working in tiny.
There's some times that you need pieces to be even smaller than the 0.01 x 0.01 x 0.01 so that's when you blueprint it and then scale the blueprint down to get the size even smaller.
