I was able to place the dimension shown by adding a point object to the top quadrant point of the arc. But I was curious if there was a way to do this without the point (or any other) object? The dimension tool didn't want to snap to the arc's top quadrant point for some reason. But maybe there's some trick I'm missing. I hope! Thanks. -Pat
While dimension dialog is active, hover the cursor over arc. From quick pick dialog select the tangent point. No need to create additional point on curve.
That worked! I had actually tried the tangent option before, but it seemed ambiguous (the selection point just moved along the curve without locking onto any particular point). What I failed to realize is that I had to select the arc before it would do that. I also was surprised not to see a quadrant point option in the QuickPic. Now that I see how this works, I expect that's because for most cases the tangent point option will get you the dimension you want.
