gosh, so many different ways to do that.
need to make some assumptions here, I am guessing that the tangent to
the arc midpoint is horizontal.
then, do you want a certain number of "segments" or a specific angle
if a certain number of segments is what serves your purpose, play with
the divide command. let it create nodes on the outer arc, and draw line
segments from node to center of the arc.
then trim back to the inner arc.
if it is an angle you want to repeat, start at the outer midpoint, draw
back to the center, trim back to the inner arc, create a polar array
based on your angle, and mirror.
I tried the first method, PERFECT,
if i except the number of segments - 64 on a quarter of circle-
next lesson i will try the second method and make a comparison between
the two drawing.
