Radius of a segment of a circle
Posted: Thu Jul 16, 2015 1:54 pm
I draw a horizontal line, 30 inches.
From its center, I draw a vertical line, 8 inches.
I draw an arc connecting these three points, which is, of course, a segment of a circle.
What is the radius of that circle?
If I tap on the arc to select it, I can go to the properties menu, and see that the radius is 18.062 inches. Is there a way to do that with the radius tool, showing that dimension onscreen?
When I tap on the arc (or anything else) to select it, it will often shift out of position. Is there a way to "lock" the screen while selecting an object, so that my clumsy fingers don't push it?
(An observation: I can drag a selection box around the horizontal or vertical lines to select them. But I can only drag the box around ALL of the objects to select the arc, which selects them all. And then, the properties dialogue does, in fact, show the properties of the arc. A bit confusing.)
If the answers are "no", please consider them as feature requests!
Thanks, and sorry about the confusion on the other forum!
