Circle tool improvement

I know that that this is too late for V14. However, if we could get an enhanced circle tool, that would be huge. Basically a circle tool that would have the center point, as part of the circle. Also a circle that would have grips on it to dynamically change the size. In addition, it would be great to have a place that we could enter the radius.

So far that would be the biggest feature that you all could add. The other stuff is fine, but this would give us way more reasons to use GM.

Thanks,

John

    John,

    Thank you for your suggestions. Have you looked at using the range ring feature? It at least allows you to specify the radius of the circle. Note the circle will be equal radius on the ground by default, so depending on the distortion of your projection it might not actually look like a circle.

    Thanks,

    Mike,

    Thanks for the idea. I do use the range ring tool at times. The problem is it is fairly cumbersome. If it get's streamlined with a few of the suggestions above, that would be the cat's meow.

    Thanks,

    John

    John,

    You can create a bunch of range rings at once if you already have the point centers as features. Just select them all with the Digitizer Tool, then select the create range ring option and you should be prompted to use all of the selected points as centers.

    Thanks,

    Mike,

    I use the range rings but am struggling to create an oval within GM 14?

    Frans,

    The range ring is a circle of fixed distance from the center to each point on the edge, so if your view projection is one with any significant distance distortion (all projections have some, but many are quite stretched, like Geographic and Mercator), your range ring will appear as an oval. If you change your view projection on the Projection tab of the Configuration dialog to one with minimal distortion at the ring location (usually UTM is a good choice) then it will look like a circle.

    Thanks,
