How to locate corner of radius for dim reference?

Hi All,
Here's my problem, I need to put dimension on the corner of thebend point as attached file. I made my model first in a sharpcorner and then make a fillet. During ordinate dimension, SW cannot recognize the corner of the radius. I do it manually to addline so that I can put dimension on the corner.

Anybody knows how to solve this?

Another thing, basing from my attached file, my water mark is ontop of some solid line and dimension, how to fix this to bringwater mark on back?

Thanks for the help,

Rgds,
