old problem - line selection in drawings

Hi, I know this thing is dragging from 2008 when I started using SW and was probably asked here 100 times. I got sw 2016, but is in new version some snapping integrated for line selection?

You probably see the problem below... Which is pain in the a...

zooming in for every dimension. Because it's always trying to select inner line first unless zoomed really closely.

Not just that... in prioritizes some invisible line (center line of a radius?) from who know where instead of outer line... this is crazy.
