I know this is in other places.. just needed to get this tip under a heading I could find...

1. select the dimension tool
2. hold the shift key and select the circle
3. while still holding the shift key ... select the second object or center line.. or whatever...
4. you will briefly see the dim still attached to the center of the circle, but as you pull the mouse parallel with the second object (drag mouse downward or sideways parallel to the object... just move the mouse you will understand.. ) the dim will snap to the tangent...


One alternative...if you want to go from the center of one circle to the tangent of another...
1. select the dimension tool
2. select the circle
3. hold the shift key and select the next circle.


In short... to get to the tangent of a circle.. hold the shift key prior to selecting the circle...


Hope someone benefits from this...

Shaun Murphy points out snap points on a circle very well... see post #7 on the following link
