Hello @seiichi_takayama,

Thanks for posting your request. Could you give exemples when this “circle guide” helps you? and why the current cross is not enough? This will help us understand what problem we would solve by adding this.

Thank you.  
Regards,  
Pierangelo

@seiichi_takayama yes, it is clear now. Thank you for providing additional information and an example. My understanding is that the circle helps to center the marks on round targets. Thereby assuring a more accurate marking. I will add this suggestion to our internal feedback board.

Thanks for letting us know and don’t hesitate to post other suggestions if you have some.

I concur, just completed a large project in mapper with round GCP’s. Not having the circle would have made the marking much less precise, and difficult.
