Is it possible to find the value of the corner radius of the rounded corners for a rectangle that was created with the Rounded Rectangle Tool?
This if for CS4.
Select the arc of one corner with the white arrow tool. copy/paste a duplicate arc. Measurement bar or Transform palate will give you the width/height, which assuming there was no rotation, is the value of the corner radius.
Hope that make sense...
Thanks for the tip. I did try it with a new box created with the Rounded Rectangle Tool and your method gave me the correct corner radius (H=W=corner radius I entered at creation). However, with the box I intended to do the measurements with in the first place, I obtain two slightly different readings for H and W.
I suspect, as Jacob does, that the rounded corner box was scaled unevenly so that the width does not equal the height. No way to tell the original radius, I am afraid, so use which ever one is more pleasing. You can also pull a round circular box as a trial. Then use half the diametre.
I had mentioned rotation because if the arc was rotated, the demensions would not give the true radius.
I don't believe there had been any modifications made to the box, except perhaps even scaling (H & W). However, I am not sure. The difference between H and W is around 0.001". In any case, Just_A_Mac_Guy's tip is very useful. It's probably wiser that I use the Rounded Corners FX next time!
The difference between H and W is around 0.001".
That is too much to be just the inherent accuracy (which is no more than about 0.001 pt), so something must have been done/gone awry.
You could also use the Effect>Convert to Shape>Rounded Rectangle (setting the Extra width/Height to 0). That would ensure that no change is made to the corner radius. You may Object>Expand Appearance at any time, to see the radius or to enable rotation and so on.
