ISSUE #2 -- LINES PERPENDICULAR TO A CIRCLE:

When attempting to draw a line perpendicular to the surface of a circle, there is NO problem -- IF your are OUTSIDE of the circle.  However, If you are INSIDE of the circle, with the SNAP to perpendicular and SNAP to intersection turned ON, the line you are drawing will not find the circumference of the circle -- if you begin the line at the center of the circle

I have tried this numerous times using the center of the circle as the starting point of the line, in which case the radial approaching the circle is ALWAYS perpendicular to the circle! 

Again:  If you're outside the circle, no problem.  If you're inside the circle attempting to draw a radial from the center of the circle to the circle, PROBLEM!  The TANGENT command works perfectly.

So...what's the answer?

Um... ALL straight radial lines drawn from the center of a circle to the perimeter are by definition perpendicular to the perimeter at the point of intersection.
