No, it’s the built in scale tool. In this case I’m using “native” scaling to distinguish between that and Fredoscale which the OP was also asking about.
I am confused however @michal.p , if you select the arc segment component we see there with the scale tool does it’s scale bounding box not appear in line with its original blue bounding box we are seeing? I’m coufused about where the larger yellow bounding box on the global axis is coming from.
