Draw a triangle inside the circle, with the edges touching the circle outlining. From the middle of the straight lines from the triangle, draw a straight line to the corner of the triangle, on the exact opposite side of the circle. Do this with all three sides of the triangle and you will have three lines crossing each other on the exact same spot, the center point. (Learned this a few days ago on the Discovery Channel: A racing car is born)

Yeah, that's what I thought to. Since I am into casemodding, I sometimes need te exact center of a circle. Unfortunately I never knew how to get that, but now I do know Very Happy

Indeed. Very smart. But isnt it very dumb of adobe if they dont have a function that calculates that for you? I mean thousands of users have to find out the exact mid-point of figures and shapes. Not all of them did watch that discovery show Wink

This is how I would do it. Make a circle in vector. Press CTRL+T and in top of the screen you can write how big you want it. Make it like 3x3 pixels. When you want it big again, just write 100x100 or something like that.

Sounds fine, but do you have the center point yet by then?

I found out a pretty nice way to do it. Select the circle of what ever shape you want to find out the mid point of and press Ctrl+T. This way you get a marker in the middle of the selection (a round marker). Now draw 2 grid lines the intersect each other precisely at the mid point.

I call it magic Wink
