I have no problem doing this. When you say the lines a "micro size" does that mean they just look smaller upon pasting? Or do they rescale to a different size when you actually measure them. It's possible that this is just an issue with zooming. (Zoom to fit window immediately after pasting.) Or maybe you are inadvertently using 1'=1' vs 1"=1', say.
