The radiusKilometers attribute was not updated when scaling a circle #221 about terra-draw HOT 1 CLOSED

Hey, thanks for following up. Yes, you are right, this won't update on Select resizing. Unfortunately this is not really possible for a couple of reasons:

1. Select mode has no concept of circles/rectangles etc, as it treats everything as a polygon and has no special behaviours for any given mode, beyond the standardised configuration flags provided
2. Once you edit the circle and distort it in any way it is deformed and not really a circle any more so the concept of a radius is no longer relevant

Select mode could be use with any number of other drawing modes, including custom ones. As such I don't think it is a wise software architectural decision to have hardcoded behaviours for modes within the Select mode.

As such this would need to be implemented in your own code and could be achieved by implementing either a custom Select mode, or if you want something simpler you could calculate the radius after any change by taking any coordinate of the circle and calculating the distance from that coordinate to the center. I hope this helps, sorry that it's probably not the answer you're hoping for.

I'm going to close this issue as it will not be being implemented in at the library level. I hope the two options provided above help you find a solution!
